Aluminum hydroxide is white powder product. Its appearance is white crystal powder, non-toxic and odorless, with the characteristics of good flow ability, high whiteness, low alkali and low iron. It is an amphitricha compound. The main content is AL (OH) 3.

1.     Aluminum hydroxide prevents smoking. It makes no dripping substance and toxic gas. It is labile in the strong alkali and strong acid solution. It becomes alumina after pyrolysis and dehydration, and non-toxic and odorless.

2.     Active aluminum hydroxide is produced by advanced technology, with various kinds of adjuvant and coupling agents to raise the property of surface treatment.

Usage:

Used as the material in various kinds of aluminates, as the retardant agent in plastic, latex industries. It is used in paper making, paints, toothpaste, pigments, drying agent, pharmaceuticals industry and artificial achate.

Active aluminum hydroxide used in plastic, rubber industries. It’s also extensive used in electrician, LDPE cable material, rubber industry, as insulating layer of electric wire and cable, restrictive coating, adiabator and conveyor belt.
