Product Manufacturing

Production Condition: choose natural magnesite mine, then calcine in kiln and then mill into customized powder size.


Application in FillerActivator and Accelerator

Activated magnesium oxide is mainly used as activator and accelerator for chloroprene rubber, fluororubber, butyl rubber, styrene-butadiene rubber; the activity of magnesium oxide can increase the crosslinking density of butyl rubber, thereby improving the physical properties of rubber stoppers ; Filler for paints, plastics, paper and adhesives.

Secondly, it can also be used as raw materials for glass, ceramics, magnesium oxide plates, high-grade thermal insulation materials, etc. In addition, activated magnesium oxide has excellent electrical insulation and alkali resistance at high temperatures, high thermal conductivity and coefficient of thermal expansion, and also has good light projection properties.
