Introduction
1、Product Introduction
The DF-5 series of magnesium hydroxide developed by Wanfeng is a magnesiumhydroxide flame retardant with a special crystal structure (hexagonal sheet). It hascharacteristics such as small particle size and smaller surface area, because it has thecharacteristics of uniform particle size distribution and finer particle size, smaller surfacearea,and physical conformity, which greatly enhances the dispersal performance of the powder inthe polymer matrix and gives the polymer material better flame retardant and machining.
performance.After coating modification, magnesium hydroxide exhibits characteristics such asimproved compatibility with polymers, increased powder fill volume, reduced viscosity, andenhanced flowability, making it the leading product for advanced composite materials suchas plastics, rubber, and special cables.
