Description
Alumina Trihydrate/Aluminium Hydroxide, simply as ATH, it’s chemical formula is Al(OH)3. Chalco’s ATH possesses low moisture content and less impurities, so it has absolute advantages as fillers for industrial products. In some countries, the product is also called alu hydroxide.
High whiteness, low oil absorption, stable performance at normal atmospheric temperature; Excellent flame retardant and insulating filler benefited from self –extinguish property, and no toxic and corrosive gases generated when thermal decomposition. Widely used as filler in solid surface, BMC/SMC, glass fiber reinforced plastics (FRP), epoxy potting compound and other composite materials, etc.
