Brucite is a natural mineral with the highest content of magnesium hydroxide in nature.
And brucite powder can widely used in PVC cable, HFFR cable compound(EVA, PE), flame
retardant panel, aluminum composite panel, roofing membranes for flame retardant.

Remark:Coated Type
Coated grades are coated with coating agent. it’s can be used for most type plastics compounds. such as HFFR cable compounds, EVA, POE, PP,TPU, TPE. It can help the powder better dispersing in the resin and fabricate the compound with high elongation at break.
Advantages
*Suitable for EVA/POE/LDPE based halogen free flame retardant formula.
*Good at HFFR cable compounds
*Similar to American, Russian made synthetic magnesium hydroxide.
*Could achieve high elongation at break.
*Higher limited oxygen index.
