Magnesium oxide is widely used in the rubber industry, and the addition of magnesium oxide in the production of rubber products can play many unexpected roles. Magnesium oxide is mainly used with the following rubbers: neoprene, CPE, bromobutyl rubber, halogenated butyl rubber, fluororubber, nitrile rubber, chlorosulfonated ethylene rubber, etc. to produce rubber products. The products produced are different, the content and ratio of magnesium oxide to be added are different, and the effect of magnesium oxide in the product is also different.
Adding magnesium oxide to rubber at the beginning of mixing can prevent early cross-linking and cyclization of neoprene rubber and increase the safety of operation. During vulcanization, it becomes a vulcanizing agent again, which acts as a hydrogen chloride acceptor and prevents the corrosion of the fibrous tissue by hydrogen chloride. Magnesium oxide can improve heat and aging resistance. The quality of magnesium oxide has a great influence on the processing and vulcanization of neoprene. When the amount of magnesium oxide is increased to 10 parts, the colloid can have higher plasticity and better storage stability.
Zinc oxide is mainly used as vulcanized rubber, which can make the vulcanization smooth. Increasing the amount of zinc oxide can improve the heat and aging resistance, but the rubber is easy to burn and the storage stability of the rubber is reduced. Extensive use can also harden the rubber and lose its plasticity. However, it can increase the vulcanization speed, and can also improve the degree of vulcanization and high temperature resistance. Generally, magnesium oxide and zinc oxide are used at the same time, which solves the easy scorching shape of the vulcanized rubber, and also has a high degree of vulcanization and a fast vulcanization speed, and the degree of cross-linking is much higher than that used alone.
Hebei Meishen Technology Co., Ltd. specializes in the production of magnesium oxide for rubber, and cooperates with many large rubber manufacturers across the country. It has rich experience and can accurately recommend suitable products for customers.
