ONYX ELITE 431

ONYX ELITE 431 is a high-purity, organic-free Alumina Trihydrate specifically designed to provide translucency, depth of pattern and soft white color. ONYX ELITE 431 exhibits a unique particle size distribution that provides the best combination of viscosity and air release for applications. A closely controlled coarse fraction top size with a large fine fraction yields rapid dispersion in resin, excellent mold flow and wet-out characteristics, resulting in minimal porosity, even pigmentation, and excellent filler reinforcement throughout the molded part. ONYX ELITE 431 is a low surface area, medium particle size flame retardant and smoke suppressant Alumina. It can be used to enhance physical properties and aid in processing.
