This highlyfilled tooling board has a higher thermal conductivitythan most plastics and a low, reliable CTE making itan excellent soft-tooling candidate for replacing yourcostly, heavy metallic tooling. This material supportshigh-temperature applications up to 480ºF (248ºC).General Questions Regarding Thermal PropertiesSince most tooling board applications are sensitive todimensional stability, process temperature, prepreg resin curecycles, autoclave pressures, thermal expansion changes,and material property mismatch problems, constructingtools that always perform as expected can be challenging.How much heat will the tooling material take?Refer to the LAST-A-FOAM Thermal Properties charton page 2. When designing your tool, also take intoconsideration its size and shape.What is the Glass Transition Temperature (Tg)?Above this temperature, the material will become “rubbery”and can exhibit plastic deformation under low mechanical orautoclave pressure loads.What is the Heat Distortion Temperature?At this temperature, when exposure times exceedapproximately four hours, the material will begin todeform under load. Under low pressure or mechanicalloads, exposure of one to three hours (as in a cure cycleor secondary heating operation) is allowable up to theheat-distortion temperature. If using vacuum-bag orautoclave-cure processes, test the tooling material underprocess conditions to ensure it is suitable and stable.What is the Continuous Service Temperature?This is the temperature at which the product can be usedcontinuously without distortion.TIP: UNDERSTANDING DIMENSIONAL STABILITYTesting Example: If you use an unconstrained beam ofLAST-A-FOAM FR-4520 (CTE of 35x10-6 in/in F) thatis 100 inches long, and heat it from 65 F to 150 F, it willgrow to 100.31 inches long. The material will shrink backto 100 inches as it cools. It is important to know the actualtemperature range throughout the process, so that thetool is designed to ensure the final part has the desireddimensions. Strength and Creep: Applying solid bonds to toolingplates will help restrain the material under heatingconditions. Such heating enables lower densityLAST-A-FOAM to creep or relax into its newconfiguration with appropriate tolerance. Avoid unsupported thin cross-sections of toolingmaterial, because heat soaking at high temperaturemay cause unpredictable movement.3
What is the Coefficient of Thermal Expansion (CTE) andwhy is this important?The CTE measures the fractional change in size per degreechange in temperature at a constant pressure. Whenselecting tooling material, it is important to match the CTEvalues of the tooling and production materials, so thatthe materials will expand and contract at the same rateswhen exposed to various curing temperatures. As withsimilar tooling materials, LAST-A-FOAM products changein dimension with changes in temperature. Because mostLAST-A-FOAM product lines are made with polyurethaneresins, their thermal expansion characteristics are typical ofmost urethane resin products. See Appendix A on page 10for individual product CTE values.BONDING RECOMMENDATIONSChoosing the Right AdhesivesYour specific design and application will drive your particularadhesive need for bonding and sealing. In selecting youradhesive, keep in mind the environment the bondedassembly will have to withstand. Make sure your sealantmaterial is compatible with the mold release and surfacecoating materials you plan to use when completing the tool.Consider these important factors: Use temperature Bond line gap-filling capacity Chemical exposure Mechanical loads Thermal expansion characteristics Ease of application Pot life of adhesiveAll rigid LAST-A-FOAM products are produced withclosed-cell resins. For bonding and sealing, a wide varietyof adhesives and coatings can be used. High-density LASTA-FOAM is comparatively easy to fill and seal. Be sureto follow the manufacturer’s safety instructions when usingany bonding, filling or finishing product.Bonding and Sealing AdhesivesThe preferred adhesives are two-part systems that can cure atroom temperature or one-part moisture curing formulations.Most polyurethane, epoxy, cyanoacrylates, or methacrylatesystems will work. See page 15 for recommended adhesives.NOTE: Neither solvent-based adhesives nor heat-curedadhesives are recommended for bonding tooling board.The solvent in the solvent-based adhesive does notevaporate from the bond line to form a solid bond. Heatcured adhesives require that the entire tool be heated tothe appropriate curing temperature in order for the heat topenetrate the bond line. This is not always practical.4MACHINING RECOMMENDATIONSNOTE: Models, tools, molds, prototypes and CNC-proofingapplications depend upon proper machine tooling for qualityproduction. It is recommended you become familiar with theproduct prior to engaging in a large project.CNC RoutingLAST-A-FOAM tooling board machines exceptionally wellon a CNC router compared with traditional aluminum tools.It is recommended you do a rough cut first, leaving 1-3 mmof material for finishing. Use caution at edges and tightcorners to avoid chipping at the start of a new pathway andwhen exiting the foam.Follow these proven guidelines: Use four-flute cutters or woodworking router bits Use high RPM and slow feed rates Use forced air on the drill bit to reduce dust andparticle build-up Keep a load on the cutter to avoid chatterUsing a Vacuum Hold-Down MethodThis approach is ideal for trimming thermoformedand compression-molded parts on a CNC routerwhere it is difficult or inconvenient to use clamps.Because LAST-A-FOAM products are closed-cell, vacuummethods can be used as a practical hold-down force inmany applications, eliminating the need for clamps. Simplydrill small holes in the tool and pull vacuum through them.Use silicone or latex seals or masking tape around the partperiphery to hold the vacuum.TIP: DEALING WITH DUSTRigid LAST-A-FOAM products are essentiallychemically inert; however, the processes ofcutting, planing, shaping, routing and sandingLAST-A-FOAM products produce dust. Whenworking with these materials, use appropriatesafety equipment to prevent inhaling foam dust.Here are some tips: Lower spindle speeds and higher feedrates tend to reduce dusting. Finish cuts typically produce the mostdust. To minimize airborne dust, use a dustcollection shop vacuum or system at thecutting head.
TIPS: HOLDING SCREW AND BOLT THREADSProduct densities greater than 20 pcf hold screws well ifthey are installed in pilot holes predrilled close to the rootdiameter of the threaded fastener.threads are easily stripped by an over-torquedfastener. Tapped thread strength is not sufficient forrepeated insertion and withdrawal of fasteners. For one-time insertion and static loads, choose High-density tooling products (such as FR-4540,coarse-thread, self-tapping sheet metal screws,drywall screws or particle board screws. To maximize thread retention, use a bonded, threadedinsert (ideally with a knurled outside surface) or anepoxy-bonded Heli-Coil insert. Although it is possible to “tap” threads into urethanefoams to establish threaded holes, these coarseEnter edges slowly. Climbinto part to reduce chippingFR-4550) hold threads better than other materials,but are not optimal alone. For greater reliability, useinserts with adhesives. To direct the location of threaded fasteners moreprecisely, pot the insert into an oversized hole andfix the insert in its proper location before the pottingcompound sets.Roll around inside radiusto avoid chatterConstant scallop with1” ball clutterClimb cut contours toavoid chippingLeave 1-3 mmafter rough cutRepair with traditional epoxy materialwith a density of 300 kg/m3Fig. 15
SEALING AND FINISHINGRECOMMENDATIONSMOLD RELEASERECOMMENDATIONSFinished Surface Preparation TipsA good final finish depends on proper surface preparation.Virtually no carrier solvents irreversibly damage LASTA-FOAM , so you have great freedom to select finishingmaterials.Using Mold Release AgentsA release agent is any chemical that is used to help releasea molded part from a mold cavity. Mold release agents areoften coated onto polymeric composite surfaces used inadhesive bonding.Using Sanding Sealers and Finishing a Bond LineMost sanding sealers will plug surface cells and fill smallvoids. You will likely need more than one coat of sealer. Forbest results, apply at least four coats of sealer and do a lightsanding between coats.A large variety of release agents can be used with LASTA-FOAM products. They can be waxes, water-borne,solvent-borne, or aerosols. Please follow manufacturerrecommendations and test ahead of time. See Appendix Bon page 15 for recommended sealing products.To finish LAST-A-FOAM across a bond line, choosean adhesive with a cured hardness similar to that of thesurrounding foam of the material surrounding the bond line,and sand.NOTE: Our Technical Data Sheets have hardnessinformation to help you match the material to the curedhardness of various adhesives.Getting the Best Results for FinishingPrepare the surface for the finish coatings of your choicewith light sanding as needed. You may only need a paintprimer on high-density LAST-A-FOAM material. If youprefer a glossy finish, use a high-gloss top coat. Followmanufacturer instructions to achieve the results you desire.See Appendix B on page 15 for recommended sealingproducts.Creative Tips for Finish Coat ApplicationsFinish coatings can duplicate virtually any surface devisedby man or found in nature, including wood, metal, rock, fishskin, feathers, and even mirror.A primer will improve surface quality, but it’s usually notneeded to improve adhesion or surface sealing. Automotiveand woodworking-grade finishes typically generate goodresults when applied to our rigid LAST-A-FOAM products.NOTE: We recommend you test your desired finishes toachieve best results. If you have questions during yourprocess, please contact our product experts in customerservice, who are happy to assist.TIP: Before using any new resin, cure profile,sealant, or tooling board, we recommendyou test under the conditions you expect tohave in production.6CURING PROCESSESSpecific cure cycles (temperature, pressure, dwell times,etc.) depend on the design and type of the tooling materialused, as well as the resin used in the composite lay-up.Achieving Dimensional Stability with Vacuum-Bag andAutoclave PressuresDimensional stability is a key consideration in advancedcomposite tooling applications where heat cures andlaminate-consolidation pressures are applied to the part.Although all tooling-grade LAST-A-FOAM is resistant towarping, subsequent machining operations can inducestress on a piece of foam. This may be evident at roomtemperature, or become apparent only after heating.Using Low-Temperature Prepregs with UrethaneTooling MaterialsAll LAST-A-FOAM products with the proper sealer, releaseand cure profile can produce high-quality parts. SeeAppendix B on page 15 for compatible sealers.Since LAST-A-FOAM tooling board products are cellularsolids, the thermal conductivity is lower than metal or evenother plastics. Longer dwell times may be needed for theresin system to reach full cure.Large-Mass Tools & High-Temperature Curing CyclesFabricating tools from large monolithic blocks is frequentlydesirable, cost effective and problem-free. However,subjecting large-mass tooling to high temperatures and ina long-duration autoclave cure cycle (e.g., 350 F for 6-plushours at peak temperature) is an exception.In this case, there is high potential for heat soaking theentire mass of the tool, which can cause a large temperaturedifference (ΔT) between the outside and inside of the tool
during cool down. This is a large difference in thermalexpansion effect and could potentially induce severestresses within the tool. Sometimes, these stresses canexceed the strength of the tool material, causing the tool tocrack or shear.Rapid heating of a tool may create similar stresses, as whena quick ramp-up in autoclave or oven temperature causesthe outside of the tool to heat much more rapidly than itscore.NOTE: Test the predicted cure cycle before production use,including ramp-up and cool-down cycles. We have observedthat most cracking occurs during the cooling process.TIP: The temperature gradient between the coreof the tool and the surface should not exceed 30ºF.Care should be taken in the cool-down cycle below220ºF; there should always be a sufficient step toensure the tool can equilibrate before cooling toambient temperature.MATERIAL HANDLING,STORAGE & SAFETYGUIDELINESFoams used in this density range have relatively lowmass and are poor conductors of heat energy. Theyabsorb heat slowly, but once heat-energy isabsorbed, they also release it slowly. Forming many partsin a short time frame using thick plastic sheets typicallytransfers substantial heat to the forming tool, potentiallysoftening the tool.High-Temperature Forming MoldsParts requiring higher forming temperatures are successfullyformed with molds made from FR-3720, FR-3730, FR4718, FR-4730, FR-4740, and FR-4800 using adequatecooling methods of parts and tools between cycles. Flexibleand rigid polystyrene, ABS, PVC and polyolefin plastics areeasily formed using LAST-A-FOAM tools.Foundry and Mold Pattern ApplicationsLAST-A-FOAM is far superior to wood for pattern making.BENEFITS INCLUDE: Dimensionally stable Durable Free of grain effects Available in large blocks up to 24’’ x 80” or custombonded to larger sizes Produced without bond joints that can fail or cause“mark off” on production Unaffected by humidity changes that can cause bondjoints to fail in wood patterns Cost-effective as a pattern substrate, (vs. the laborexpense of “blocking up” a large foundry or moldpattern out of small wood pieces)When storing and handling rigid LAST-A-FOAM , treat itlike any other potentially combustible organic solid. Theproducts are essentially chemically inert. Processes used inmanufacture will create dust. See tips for dealing with duston page 4.TOOLING & MOLDSAPPLICATIONSUsing HDU MaterialsEasily machined and far less costly than aluminumand other substrates, they are a practical option forvacuum-forming low-rate and prototype parts. Here aresome recommendations to keep in mind with each processmethod.Key Factors to Consider When Thermoforming Plastic sheet thickness Forming temperature How often the tooling is “cycled” to form the part7
LAST-A-FOAM Tool in Bagging Layup ProcessFig. 2Resin Infusion, Prepreg Layup & Autoclave ProcessesLAST-A-FOAM FR-7130, FR-7140 and FR-4800These boards provide ample strength to withstand vacuuminfusion, autoclave and vacuum-bag pressures in toolingused for VARTM, SCRIMP, RIFT and other resin-infusionprocesses. All major American airframe manufactureshave relied on LAST-A-FOAM products from this line, tobuild process tooling for airworthy composite structures.Manufacturers value the: Ease of machining Large block sizes Predictable high-temperature performance Cost per volumeFiberglass Molds and PlugsLAST-A-FOAM is flame-retardant, making it safer tostore than styrene-based foam products. The moderateTg allows it to withstand the short-term exothermiccuring of unsaturated polyester, epoxy and vinyl esterresins. Thanks to its relatively low cost and high strength,FR-7100 is usually the best choice. It is available in blocksup to 35” tall. This foam is highly resistant to tooling gelcoats, styrene monomer, solvents, paints, and the coatingsused in the FRP composite industry.Using Soft Tools up to 400ºFLAST-A-FOAM FR-4700The FR-4700 tooling board is a rigid, high-temperature,hybrid tooling board that is designed for prototypemachining, prepreg composite layup tooling, vacuum formtooling, tool proofing, pattern making, and master modelmaking.Using Soft Tools up to 480ºFLAST-A-FOAM FR-4800The FR-4800 Tooling Board is a rigid, highly-filled,high-temperature tooling board that is ideal for toolingapplications in place of heavy metallic tooling. Similarto the FR-4700, the FR-4800 is an option for prototype8Bagging Schematic for HT Autoclave CureCourtesy of Hexcel Corporation and the HexTool MGI User Guide.Fig. 3machining, vacuum form tooling, tool proofing, resininfusion, and other various tooling board uses. Its low CTEand improved thermal conductivity makes it a formidableoption for a non-metallic, high temperature tooling board.ApplicationAll of our LAST-A-FOAM Tooling Boards are non-abrasiveand can easily be machined to meet product applicationrequirements. It can be bonded to itself or other substratesusing urethane and epoxy adhesives that are rated forappropriate end-use temperatures.Key Performance Benefits Applications up to 480ºF (248ºC) peak temperature Continuous use up to 400ºF (204ºC) Compatible with commercial prepregs No outgassing or cure inhibition Dimensionally stable Large block size reduces bond lines Compatible with most surface finishing materials Easily machinableSee next page for special FR-4800 user guidelines.
FR-4800 HIGH-TEMP. TOOLING & MOLD RECOMMENDATIONSBonding AdhesiveThe FR-4800 tooling board will not inhibit adhesive curingor curing of commercial prepregs. Select an adhesiveappropriate for the processing temperature. See AppendixC on page 16 for recommended adhesives.Bonding ProcessSurfaces to be bonded must be clean, dust-free, flat,and square. Apply adhesive to both surfaces so they arecompletely coated. Apply more adhesive in the middle assqueeze-out will occur. For best results, apply even pressuresuch as a vacuum bag. Good results have been obtainedusing a 1/4” or 1/8” notched trowel to apply the adhesive.NOTE: It is best to use a room-temperature cure adhesive.Trying to achieve an elevated temperature cure on a largemass of foam can take a very long time and can result incracking of the foam if not cooled slowly.Follow the manufacturer’s recommendation for curing theadhesive.Sealant CompoundsThe FR-4800 is designed with a hard, smooth finish anddoes not require the use of sealant compounds. However,if planning to apply a liquid mold release agent, sealing thetool surface is recommended. NOTE: Best results havebeen obtained using Airtech ToolTec CS5 adhesiverelease film. This all-in-one product is a sealant, surfacefinish and release agent. For curing temperatures lowerthan 275 F (135ºC), a lower cost solvent-borne acrylic resinor a cross-linking vinyl ester resin will suffice. See AppendixC on page 16 for product recommendations.Mold Release AgentsA number of mold releases can be used. The end userneeds to test compatibility with the resins and temperaturesneeded in the production process. A mold release agentshould not be used if the FR-4800 has an unsealed surface.Cold down rate is recommended at 1ºF/min. Testing was doneup to 6ºF/min on 4” block with no cracking.CNC Routing recommendationsThe FR-4800 tooling board will machine well comparedwith traditional aluminum tools. The FR-4800 toolingboard does wear cutting tools much faster than otherLAST-A-FOAM products. As a result, carbide tooling isrecommended. It is also recommended you do a roughcut first, leaving an extra 1-3 mm for finishing. Use cautionwith edges and tight corners to avoid chipping at the startof a new pathway. See Fig. 1 (page 5) for basic CNCrecommendations.9
