Surface active aluminium hydroxide
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

Description
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.
Product properties
| 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 |
