Mg(OH)2 Applications
It is more suitable for high -temperature processing plastic requirements. Magnesium hydroxide can be used as a flame retardant such as polyethylene, polypropylene, polyvinyl chloride, triathoolite, unsaturated polyester and other plastic and rubber. It can also be used as a flame retardant for coatings.
Magnesium hydroxide is used as wastewater treatment, desertation of heavy metals, treatment of seal and dyeing wastewater, treatment of arsenic and wastewater, etc.
Magnesium hydroxide used as smoke desulfurization.
Service and Quality
Our natural fine ground Magnesium hydroxide is intensively used as a flame retardant in thermoplastic and elastomer polymer compounds. It can also be used as a component of paints and resins, TPO roofing and flooring applications and in Aluminum Composite panels.
