Features and Main application:
- YR6A Magnesium hydroxide fire-retardant is high purity Mg(OH)2,the surface is specially treated with vinyl silane
- because surface is after organic reaction,so it greatly reduces surface energy, and improves the dispersion and liquidity in organic matter accordingly,
- as a no halogen flame retardant,it can be used in plastic. such as PE,PP EPDM ,Rubber.Low smoke density and high thermal stability. initial decomposition temperature is about 340 degrees centigrade.No Poisonous and causticity air when degradation.
- Because of vinylsilane surface treatment,it is good for improving the compatibility of polymer and filler when casting mold and modification.
- With pretreatment of powder when chemical reaction,it will deduce clients’ input for facility and processing steps.further Lower the cost of facility and labor
