Features and Main application:
a) YR6C Magnesium hydroxide fire-retardant is high purity Mg(OH)2, ,the surface is specially treated with stearic acid.
b) because surface is after organic reaction,so it greatly reduces surface energy, and improves the dispersion and liquidity in organic matter accordingly,
c) 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.
Storage and instructions:
Keep it in dry environment with room temperature
