Applications and Huber ProductOfferings for Flame Retardance andSmoke Suppression1. Fiberglass Reinforced Polyester Molding and PultrusionGround ATH 3 to 25 microns SB grades Micral grades MoldX Optimized ATH gradesATH is a cost-effective, non-reactive flame retardant used in a wide variety of moldingcompounds. Huber has a complete range of particle sizes to allow the compounderto achieve high loadings of ATH which improve flame retardant performance andreduce the amount of resin in SMC, BMC, pultrusion and other molding applications.2. Wire and Cable CompoundsTreated precipitated and ground ATHUntreated ATH 1-6 micronsTreated and untreated MDHMolybdates Hymod gradesHydral and Micral gradesVertex and Zerogen gradesKemgard gradesWire and cable applications require flame retardance and low-smokegeneration. Huber has a broad line of molybdate, ATH and MDH productsthat impart outstanding smoke suppression in thermoplastic wire and cableproducts. Especially in high-performance applications, chemically-treated ATHand MDH products offer these advantages compared with untreated ATH: Improves dispersion uniformity .Increases color stability Higher throughput rates Improves physical properties and Enhances flame retardant performance electrical performance3. Engineering ThermoplasticsTreated MDHMolybdates Vertex grades Kemgard gradesThe MDH decomposition temperature of 330 C (626 F) makes it ideal foruse in thermoplastic systems which compound at high temperatures such as: Polypropylene Polycarbonate Polyamide Polybutylene Terephthalate (PBT)Huber’s product line includes specialty-treated MDH products which workwell in polyamide systems. Polyamide formulations containing Kemgard 981 and antimony oxide have improved thermal stability properties versususing antimony oxide alone.4. Roofing MembranesUntreated ATHTreated ATHTreated MDH products Micral grades Hymod grades Vertex 60 seriesHuber developed surface-modified ATH and MDH products to provideoutstanding physical properties, water-resistance, fast dispersion and flameretardant performance for membranes used in roofing applications. MDH isan excellent flame retardant, but its high polarity surface makes it somewhatincompatible with low polarity elastomers such as EPDM rubber andthermoplastic polyolefin (TPO). Treating the surface of the MDH allows itsflame retardant performance to be incorporated into roofing membranes.4
5. Silicone RubberTreated precipitated and ground ATH Hymod SP and SG gradesATH is used in silicone rubber to reinforce the compound and impartarc track resistance. In order to achieve outstanding physical and electricalperformance in peroxide-cured silicone rubber compounds, Huber developedits SP surface treatment products. Its low-surface energy facilitates mixingand allows for high filler loadings. The compounds do not stick to moldsand remain very hydrophobic. Hymod M9400 SP is specifically designedfor high voltage silicone rubber insulators.6. RubberUntreated ATHTreated ATHMolybdates SB and Hydral grades Hymod grades Kemgard gradesATH is commonly used in organic rubber compounds such as EPDM, EVA and SBRfor smoke suppression and flame retardance in applications such as belts, hosesand carpet backing. An example is the mining industry, which has established newnon-halogen fire retardant Mine Safety and Health Administration (MSHA)requirements. ATH and Kemgard products can be used in mining applications.7. Adhesives, Caulks and SealantsUntreated ATHTreated ATHMolybdates SB and Micral grades Hymod grades Kemgard gradesSome adhesives, caulks and sealants used for automotive and buildingmaterial applications are required to meet certain criteria for flameretardance and low-smoke generation.8. Carpet Backing and TextilesUntreated ATHMolybdates SB grades Kemgard gradesLatex, urethane and vinyl binders, used in fabric and carpet manufacturing,are flammable. Coarse ATH is a standard flame retardant for commercialand industrial carpet applications, and molybdates help to reduce smokegeneration.9. CoatingsUntreated ATH SB , Micral and SpaceRite gradesSB-432 is the standard ATH grade that has been used for elastomeric roof coatingsfor over 20 years. Gel coats used in thermoset applications often contain ATH.Fine particle size grades of ATH such as SpaceRite S-3 can effectively extendwhite and color pigments in coatings while maintaining high gloss.5
Surface Treatments Increase PerformanceTo aid processing and improve physical, electrical, flame or chemical resistance properties, Huber has developed a broadline of high-performing, surface-modified grades. Surface treatments applied to metal hydroxides can benefit you in thefollowing three areas:1. Powder Handling and Storage3 Increase shelf life (MDH)3 Reduced moisture absorption (during storage)3 Improved powder flow2. Compounding and Processing3 Improved compatibility with polymer3 Better wet-out3 Better, faster dispersion3 Lower viscosity, higher loadings3 Greater throughput rate3 Color stability3 Reduced absorption of expensive additives3 Improved cure properties3.

kemgard.comKemgard flame retardants and smoke suppressantschemically influence the formation of organic char,effectively insulating the polymer from the heat andoxygen source thereby lowering heat and smoke release.Kemgard grades are manufactured by patented processesin which molybdates are precipitated on an inert core. This“coated core” approach makes more efficient use of themolybdate species by maximizing the active surface area,and at a much lower cost than pure molybdate chemicals,such as ammonium octamolybdate (AOM).Char FormationKemgard 911CChar FormationAOMKemgard LowersSmoke by CharFormation Source: NBS Smoke Samples – Compounds contained 60 phr ATH; 3 phr Sb2O3; 7 phr stabilizer; 20 phr Solutia 2148;20 phr FRP-45; and 20 phr smoke suppressant.Huber’s Key Kemgard Product Offerings Kemgard Products Median Particle Specific DescriptionGravity(White Powder Appearance) Size, MicronsApplicationsKemgard 4252.63Calcium molybdate zinc complexFlexible PVC; Calendered film; Caulks, adhesives & sealants;WallpaperKemgard 5013.72.9Calcium molybdate complexFlexible PVC; Rigid PVC; Wire & cable; Calendered film;Caulks, adhesives & sealants; Epoxy; WallpaperKemgard 911A2.73Calcium molybdate zinc complexFlexible PVC; Calendered film; Caulks, adhesives & sealants;WallpaperKemgard 911B2.35.1Basic zinc molybdate compoundFlexible PVC; Wire & cable; Calendered film; Caulks,adhesives & sealants; Epoxy; WallpaperKemgard 911C3.32.8Zinc molybdate / Magnesium silicate complexFlexible PVC; Rigid PVC; Wire & cable; Carpet backing;Polyamide; Calendered film; Caulks, adhesives & sealants;Epoxy; Polyolefins; Electrical connectors; Wallpaper;Neoprene rubber; Vinyl plastisolKemgard 9814.44.2Basic zinc phosphate complexFlexible PVC; Polyamide; Calendered film; Caulks,adhesives & sealants; Polyolefins; Electrical connectors;PolyesterKemgard 110022Zinc molybdate / Magnesium silicate complexFlexible PVC; Rigid PVC; Wire & cable; Polyamide;Calendered film; Epoxy; Electrical connectorsKemgard HPSS23.5Basic zinc molybdate / Magnesium hydroxide complexFlexible PVC; Wire & cable; Carpet backing; Epoxy;Vinyl plastisolKemgard MZM22.6Zinc molybdate / Magnesium hydroxide complexFlexible PVC; Rigid PVC; Wire & cable; Polyamide;Calendered film; Caulks, adhesives & sealants; Epoxy;Polyolefins; PolyesterKemgard 700Z2.53Zinc molybdate / Zinc borate complexPolyolefins; PVC; Polyamide7

This is a draft report on the safety of alumina and aluminum hydroxide as used in cosmetics. Alumina is reported to function in cosmetics as an abrasive, absorbent, anticaking agent, bulking agent, and opacifying agent; aluminum hydroxide is reported to function as a buffering agent, corrosion inhibitor, and pH adjuster (Table 1).
This report addresses the safety of the inorganic hydroxides calcium hydroxide (also known as calcium hydrate or slaked lime), magnesium hydroxide, potassium hydroxide (potassium hydrate or potash), and sodium hydroxide (sodium hydrate, lye, or caustic soda). These ingredients are all alkaline salts and are reported in the
