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.
