Although magnesium oxide is not the main material in rubber, it plays a very important role.

Magnesium oxide can be used as vulcanizing agent, active agent, and filler; It can increase the fixed elongation stress of vulcanized rubber and prevent glue burning. It can increase the alkalinity of the compound, at the same time has the effect of acid absorption, increase the heat and thermal conductivity, and is conducive to the improvement of the vulcanization rate.

1, magnesium oxide in nitrile rubber can be used as a heat-resistant adhesive reinforcing agent.

2, it is used as vulcanizing agent and active agent in chloroprene rubber, and is used as anti-coke;

3, it is used as an acid absorber in rubber containing halogen.

4, as a thickening agent in the composite material.

5, improve the rubber temperature resistance grade, the effect is obvious.

6. It can increase the bonding performance with the metal skeleton and improve the rolling property of the compound;

7, in the halogenated butyl rubber can be used as curing agent; Sometimes it's a filler.

8,,There is also the role of absorbing free halogens that are decomposed by heat.

9, magnesium oxide is often used in alloy glue, such as using PVC or CM glue, which can make the product not lack of sulfur.
