Aluminium hydroxide is additive type of inorganic
fire retardant, its features include halogen-free,
low fume, low toxicity, drop-resisting, good
resistance to flame, low cost. It can improve
arc resistance, impact resistance and bending
strength . It is mainly used in fire retarding
conveying belt, air duct cloth, rubber pipe,
wire cable, coating, adhesive, and so on.
