Product Details
Introduction
Magnesium hydroxide is an inorganic flame retardant filler for polymer-based composite materials with good application prospects. Like aluminum hydroxide, magnesium hydroxide flame retardant relies on the chemical decomposition of chemicalbook to absorb heat and release water when heated to play a flame retardant role. Therefore, it has the advantages of non-toxicity, low smoke, and the magnesium oxide generated after decomposition has stable chemical properties and does not produce secondary pollution.
This series of products uses a variety of high-purity raw materials and hydrothermal synthesis technology to prepare high-quality magnesium hydroxide flame retardants. The unique surface shaping and modification technology has the characteristics of high purity, high whiteness, ultra-fine, low specific surface area, etc. It is suitable for flame retardant applications and other uses for materials such as plastics, rubbers, and elastomers.

Application
Magnesium hydroxide is an excellent flame retardant for plastics and rubber products.
Magnesium hydroxide can be used as a flame retardant for plastics and rubbers such as polyethylene, polypropylene, polyvinyl chloride, EPDM rubber, and unsaturated polyester. It can also be used as a flame retardant for coatings.
In terms of environmental protection, it can be used as a flue gas desulfurizer, replacing caustic soda and lime as a neutralizer for acidic wastewater and an adsorbent for heavy metals.
