[ Product Introduction ]

Surface active aluminum hydroxide is a product that uses silane, stearic acid, titanate and other coupling agents to organically modify aluminum hydroxide powder through a special process, so that the product has good flame retardant effect, low bulk density, and is more stable at room temperature. Active aluminum hydroxide can improve the combination and processability of aluminum hydroxide and resin, so that it has dual functions of flame retardant and filling, giving the product excellent comprehensive performance The addition of this product to rubber and other composite materials not only makes the product flame retardant, smoke suppression and self extinguishing, but also enhances its resistance to electric leakage, electric arc and abrasion. It can be widely used in electrical LDPE cable material, rubber, wire, cable insulation layer, sheath layer, thermal insulation material, conveyor belt, adhesive, etc.

Aluminium hydroxide micro power VS. Surface active Aluminium hydroxide
Product	Aluminium hydroxide micro powder	Surface active Aluminium hydroxide
Surface polarity	Hydrophiliity and oleophobic	Hydrophility and oleophobic/hydrophilicity and olephilicity（chosed by your requirements）
liquidity	Average	Perfect
Amount added	Average	Increased
Flame resistance	Improved	Highly improved
Mechanical property	Hard，easy to be teared and cracked	To keep the flexibility of material，to increase tensile strength and elongation at break
insulation	Normal	Perfect
Processability	High vicosity，low melt index ，not convenient for processing	Low vicosity，increase melt index, convinient for processiong
Summary	The small the particle size is, the easier it is to agglomerate. It is not easy to disperse uniformly in the organic medium, and the binding force with the base material is poor. It is very easy to cause interface defects, leading to material performance degradation	The particles are not easy to agglomerate and have good dispersibility. They can form strong chemical bonds with organic materials and firmly combine with each other to improve flame retardancy
