Applications
AL(OH)3 is one inorganic fire retardant. It has not only property as fire retardant, but good performance to reduce smoke and toxic gas, anti drop etc. So AL(OH)3 is widely used in plastic and rubber, such as PP , PE, EVA, ABS, HIPS, and PVC etc.
Normally, AL(OH)3 additive amount is very high, it is easy 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, Phosphor us , PBDEs, synergism is very good that can improve the performance considerably.
AH20 grade is surface treated by non-polar polymer of Stearic Acid, 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.
