What role does magnesium oxide play in the formulation?

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

Magnesium oxide can be used as vulcanizing agent, active agent, and filler; it can improve the tensile stress of vulcanizate and prevent rubber burning. It can increase the alkalinity of the rubber compound, at the same time, it has the effect of acid absorption, increases the heat resistance and thermal conductivity, and is beneficial to the improvement of the vulcanization speed.

1. Magnesium oxide can be used as a reinforcing agent for heat-resistant rubber in nitrile rubber.

2. Used as vulcanizing agent and active agent in neoprene, as well as anti-scorch effect;

3. It can be used as acid absorber in halogen-containing rubber.

Fourth, as a thickener in composite materials.

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

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

7. It can be used as vulcanizing agent in halogenated butyl rubber; sometimes it is used as filler.

8. It also has the function of absorbing free halogens decomposed by heat.

9. Magnesium oxide is often used in alloy glue, such as PVC or CM glue, so that the product will not be deficient in sulfur.
