HN-434

HN-434 by Huber Engineered Materials is alumina trihydrate. Acts as a flame retardant. It is halogen–free, with fine particle size that provides low cost flame retardant and smoke suppression in a variety of applications. The particle size distribution is specifically designed for low viscosity, high filler loading levels, and excellent processing characteristics, up to 200°C. Excellent mold flow and wetout characteristics result in superior surface profile with minimal porosity, even pigmentation and excellent filler and reinforcement distribution throughout the molded part. HN-434 is suitable for spray-up or hand-lay up FRP applications, filament winding, panel production, resin injection, foam materials, cast polymer and epoxy parts.
