High Whiteness Fine Power Flame Retardant Filler Aluminum Hydroxide For composite insulator/ Cable Wire/ Rubber Plastic
Aluminum hydroxide, with the chemical formula Al (OH) 3, is the hydroxide of aluminum. Due to its acidity, it can also be called aluminum monohydrate (HAlO2 · H2O), but in actual aqueous solutions, it reacts with alkali to form tetrahydroxyaluminate Al (OH) 4-. It is divided into industrial grade and pharmaceutical grade according to its purpose.

01
There are more hydroxyl with certain activity on the surface of aluminum hydroxide before processing of it’s surface. It is difficult to be dispersed and opened up, which will affect performance of it’s properties. Surface modification is needed to reduce and remove the brittleness and performance degradation of adding aluminum hydroxide and increase it’s compatibility with organic interface. Oil absorption will reduce a little for modified aluminum hydroxide, while dispersity increase comparing with the original one

Application In Rubber plastic industry
1-Low oil absorption, hydrophobicity strengthened
2-Good dispersity, no agglomeration, better anti- precipitation
3-Crosslinking increase after modification
4- Obscure perssad cross section combination point and better dispersibility
Aluminum hydroxide is the inorganic flame retardant additives which is the most widely used. As a flame retardant, it can not only resist flame, but also prevent smoke, drip and poisonous gas. As a result, it obtains the widespread and increasing application.Range of application: thermosetting plastics and thermoplastic plastics, synthetic rubber, painting and building materials industries. At the same time, the aluminum hydroxide is also basic raw material in electrolytic aluminium industry, so it is also very widely used here.
Packing: laminating bags of 25 kg or 40 kg net each with plastic inside.
Shipping: it’s non-dangerous goods but should be prevented from being affected with damp, rain and packing damage.
Storage: store in a dry, ventilated warehouse.
