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-50SP grade has high whiteness and big particle size,it is mainly use in artificial marble etc field.
