High Purity Magnesium Hydroxide for Magnesium Stearate
Magnesium stearate is a multifunctional additive widely used in pharmaceutical, food and polymer material industries. Magnesium hydroxide, as its synthetic raw material, plays a key role in process optimisation and product quality control.
In silicon steel insulating coatings, magnesium hydroxide is mainly used as a functional filler to improve the insulation, corrosion resistance and high temperature stability of the coatings, and is particularly suitable for environmentally friendly coating systems for non-oriented silicon steel.
In nylon (PA)-based thermally conductive plastics, magnesium hydroxide assumes the dual roles of flame retardant and thermally conductive enhancement at the same time, but it needs to overcome the bottlenecks of poor dispersion and reduced mechanical properties.
