INQUIRY

1. Magnesium hydroxide fire-retardant is high purity Mg(OH)2,

2.because surface is after organic reaction,so it greatly reduces surface energy,
and improves the dispersion and liquidity inorganic matter accordingly,

3.as a no halogen flame retardant,it can be used in plastic. such as PVC-P,PVC-U,PE copolymer
and rubber.Low smoke density and high thermal stability. initial decomposition temperature is about 340 degrees centigrade.No Poisonous and causticity air when degradation.
