The ZS-5 series developed by our company is a magnesium hydroxide flame retardant with a special crystalline structure (hexagonal sheet), due to its uniform particle size distribution and finer particle size, small specific surface area, regular morphology and other characteristics, greatly improve the dispersion of powder in the polymer matrix, giving polymer materials better flame retardant and processing properties.
The coated magnesium hydroxide improves the compatibility with the polymer, increases the filling amount of the powder, reduces the viscosity, improves the melting finger and other characteristics, and is the leading product of advanced composite materials such as plastics, rubber and special.
