Product Name: Aluminum Hydroxide
CAS No. :21645-51-2
EINECS No.:244-492-7
is neutral substance that can react with acid and alkali both. ATH-1 grade is widely used as fire retardant in
plastic and rubber industry.
Fire Retardancy
ATH-1 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-1 additive amount is very high that is up to 30-60phr;it is easy to influence the mechanical properties of
thematerial, 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 isvery good that can improve the performance
considerably.ATH-1 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.
