Low Silicon Magnesium Oxide

The role of magnesium oxide in rubber
1. Magnesium oxide can be used as a reinforcing agent for heat-resistant rubber in nitrile rubber. Adding an appropriate amount of magnesium oxide to the chloroprene rubber can increase the tensile strength, the tensile strength and hardness of the vulcanized rubber, and neutralize a small amount of hydrogen chloride generated during the vulcanization or the product under sunlight, but the heat resistance is slightly poor.
2. Adding magnesia in the mixing of neoprene can prevent scorch during processing and improve the scorch of the rubber during storage. It can prevent early crosslinking and cyclization of neoprene and increase the safety of operation. . And in the mastication, it also has the role of plasticized rubber. In the vulcanization process, it becomes a vulcanizer and acts as a hydrogen chloride acceptor to improve the strength of the rubber compound and prevent the hydrogen chloride from eroding the fibrous structure.
3. It can be used as an acid absorber in halogen-containing rubber. As a thickener in the composite.It can be used as vulcanizing agent and filler in halogenated butyl rubber.In addition, magnesium oxide also improves the temperature resistance grade of the rubber, increases the bonding property with the metal skeleton, improves the wrapping property of the rubber compound, and absorbs the free halogen which is decomposed by heat.
