  • HCW-103 Powder level Aluminium hydroxide
  • Product Introduction

    High-purity, superfine, high white aluminum hydroxide as white loose powder, high whiteness, low bulk density, stable at room temperature, thermal decomposition generate alumina dehydration. This product is different from other flame retardant material, it does not produce toxic and corrosive gas pyrolysis, and pyrolytic heat absorption and release water vapor, can make the products flame retardant self-extinguishing, thus in advanced composite materials such as plastic, rubber, this product is added to the not only make products with flame retardant smoke abatement effect, and leakage resistance, arc resistance, abrasion resistance performance enhancements.
