Onyx Elite® 431
Onyx Elite® 431 initiates a new standard for alumina trihydrate fillers. Onyx Elite® 431 is a color controlled high-purity, organic-free Alumina Trihydrate specifically designed to provide the translucency, depth of pattern and soft white color that are so important to the cast polymer industry. Onyx Elite 431 is a high brightness product exhibiting a unique particle size distribution that provides the best combination of viscosity and air release for cast polymer. 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. A complete range of surface modifications is available to aid in processing and enhance physical properties.
