The difference between zinc oxide powder and zinc carbonate as activators in the rubber industry.

The difference between zinc oxide powder and zinc carbonate as activators in the rubber industry.

Zinc oxide powder is an important rubber chemical in the rubber industry and is generally used as an active agent and vulcanizer.

The difference between zinc oxide and zinc carbonate as activators in the rubber industry.

Same point:

Zinc carbonate and zinc oxide powder have a common function to activate accelerators to speed up vulcanization.

difference:

Compared with zinc oxide powder, zinc carbonate has a lower zinc content.

One feature of zinc carbonate is that it has better transparency than zinc oxide powder and no whitening. It is generally used to manufacture sulfur-vulcanized translucent rubber products.

Another feature of zinc carbonate is that it will significantly increase the hardness of the rubber.

Zinc oxide powder can not only speed up the vulcanization rate, but also has a certain whitening and reinforcing effect. Zinc oxide powder  is often used to enhance the color during color mixing, and can improve the aging resistance of the vulcanizate and the thermal conductivity of the product.

About 50% of zinc oxide powder is used in the rubber indus
