Why test the purity of MST® Zinc oxide powder for rubber Free Sample? How does purity affect rubber?

If the Zinc oxide powder for rubber added in the production of rubber contains a certain amount of impurities, it will affect the performance of the rubber:

1) The high content of iron, lead and copper in the Zinc oxide powder for rubber Free Sample added to the rubber compound will cause the rubber product to change color;

2) The Zinc oxide powder for rubber added to the rubber contains cadmium to prevent the activation of zinc oxide on certain accelerators.

3) The Zinc oxide powder for rubber added to the compound contains copper and manganese which will damage the aging performance of rubber products.

4) The purity of Zinc oxide powder for rubber added to the rubber compound is not enough, and it also affects the degree of rubber vulcanization;

Therefore, testing the purity of Zinc oxide powder for rubber Free Sample is a very meaningful analysis item, and it is also very important in rubber production;

The high-purity indirect method MST® Zinc oxide powder for rubber Free Sample produced by MST uses strict materials, selects "No. 0" refined zinc from top domestic metallurgical companies, and adopts the most advanced production technology and the best testing methods.
