Features:
- Magnesium hydroxideis a new type of inorganic fire-retardant, as a green and environmentally friendly flame retardant .it is halogen free, low smoke, non-toxic, resistance drops, and also can neutralize acid and corrosive gases produced during fuel combustion.
- 2.)We has succeeded in production hexagonal platelet magnesium hydroxide, which relys on special technics: advanced production techniques and adopts chemo synthesis ,diameter control and temperature control by stages etc, High purity, good dispersion, narrow distribution of particle size and particle is like hexagonal platelet.
Main application and advantage:
- As a non-halogen flame retardant, It can be adopted in plastics and elastomers. low smoke density and high thermal stability, initial decomposition temperature is about 340 degrees centigrade . Suitable for high-temperature mixing processing, good dispersion and fluidity in the resin, and also can improve the compatibility of polyester.
- As a high loading and additive flame retardant, It can be widely used as fire retardant and smoke suppressant in range of plastics and rubber, such as PE, PP, PVC, EVA, ABS, TPE etc.
- it can replace organic flame retardants, inorganic flame retardant ATH, which can greatly improve the thermal stability. Reduce the abrasion of machine and mold made by inorganic flame retardant. Prolong working life of facility,
- Magnesium hydroxide after surface treatment can be filled to organic material in high density, improving the material’s performance.
