The activity is an important factor to measure the quality of magnesium oxide. As one of the main inorganic activator, adding little magnesium oxide can improve sulfidity of rubber greatly. In rubber industry, magnesium oxide and zinc oxide are playing the roles of liquidity and antioxidant ability, and optimizing the tensile strength and impact resistance of the rubber. Therefore, magnesium oxide is one of the important compound of halogenated rubber.
In chloroprene rubber production, magnesium oxide and zinc oxide are mixture and used as vulcanizing agent, in this way, magnesium oxide can reduce the activity of zinc oxide, then have the effect on slowing down the vulcanization rate, to avoid appear the problem of early crosslinking. Meanwhile, magnesium oxide can also have the effect of acid acceptor, and prevent the charred and cyclization, usually added at the beginning of the mixing. Secondly, the activity of magnesium oxide, that is to say iodine absorption value, has an big influence on scorch resistance performance of CR, even more, has a certain influence on modulus, tensile strength and hardness.

Important Uses of Magnesium Oxide in Rubber Industry

Activity is the important indicators to measuring the quality of magnesium oxide for rubber industry. In the rubber production, active magnesium oxide as one of the important inorganic activator, only add a small amount can greatly improve the degree of vulcanization.
You have to know, magnesium oxide, the same with zinc oxide are playing the role of liquidity and antioxidant ability, optimizing the tensile strength and impact resistance of the rubber. So they are the important compounds of halogenated rubber. In CR, magnesium oxide and zinc oxide mix as a curing agent, then magnesium oxide can reduce the activity of zinc oxide, to have the effect on slow down the vulcanization rate, in order to avoid crosslinking problems in the early time. Meanwhile, magnesium oxide can also have the effect of acid acceptor, to prevent the charred and cyclization. Secondly, the activity of magnesium oxide, that is iodine adsorption value, have a big influence on scorch resistance performance, tensility, tensile strength and hardness.
In addition, light magnesium oxide is also the frequently-used kind in rubber production. Most of the time, it plays the same role with active magnesium oxide. In conclusion, magnesium oxide plays an important role in rubber industry.
