General introduce
ATH is one white powder without smell; it is neutral substance that can react with acid and alkali both. ATH-10 grade is widely used as fire retardant in plastic and rubber industry, and paper making is one important application for ATH-10 grade.

FIRE RETARDANT
ATH is one inorganic fire retardant whit low cost. It has not only property as fire retardant, but good performance to reduce smoke and toxic gas, anti drop etc, so ATH become the most widely used fire retardant in plastic and rubber, such as polyesters, acrylics, ethylene vinyl acetate, epoxies, PVC and rubber.

Normally, ATH additive amount is very high that is up to 30-60phr;
it is easy to influence the mechanical properties of the material, so its quantity should be controlled. When AL(OH)3 is composited with other types of fire retardants, such as Zinc Borate, Phosphorus, PBDEs, synergism is very good that can improve the performance considerably.
ATH-10 grade is also used in paper industry as surface coating, filler or flame retardant.
ATH-10 can improve the whiteness, opaqueness and ink absorption of the paper.
ATH-10 is widely used in SMC,BMC field as filler and flame retardant. Normal dose is around 150PHR.
ATH-10 grade can be surface treated by non-polar polymer of Stearic acid or Silicon Oil, the compatibility and combination with plastic material will be improved so that it is easy to evenly distribute into material, then the performance of fire retardant and mechanical properties is better than normal grade AL(OH)3.
