he role of magnesium oxide in rubber formulations

Although magnesium oxide is the main material in rubber, it plays a very important role.

Magnesium oxide can be used as vulcanizing agent, active agent, filler; it can increase the fixed tensile stress of vulcanized rubber prevent the rubber burning. It can increase the alkalinity of the compound, at the same time it has acid absorption effect, increases heat resistance thermal conductivity, 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 active agent in neoprene rubber, also has anti-scorching effect;

3. It is used as an acid absorbing agent in halogen-containing rubber.

Fourth, as a thickener in the composite material.

5. Improve the rubber temperature resistance level, the effect is obvious.

Sixth, it can increase the bonding performance with the metal skeleton improve the roll wrapping property of the compound rubber;

7. Can be used as vulcanizing agent in halogenated butyl rubber; sometimes as filler.

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

9. Magnesium oxide is often used in alloy adhesives, such as PVC CM compounds, so that the products will be under-sulfur.
