HN-434

Technical DataSheet | Supplied by Huber Engineered Materials

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.
