What role does zinc oxide play in rubber
- Sep 06, 2018 -

It mainly plays the effect of promoting agent on manufacturing tires, activating the function of promoting input, and improving curing power. The application amount in the formula is about 1-5%, and it plays the effect of promoting agent.

Zinc Oxide

Zinc oxide is an essential additive for the rubber and tire industries. It is also used as a sulfurizing active agent and reinforcing agent for natural rubber, synthetic rubber and latex, and as a coloring agent.

For example, in the v-belt, it can not only replace the common zinc oxide by the same amount, but also cut the dosage by 1/2 to 1/3, so that the various functional indicators of rubber are stable and the vulcanization function is not affected, reducing the use of zinc oxide by replacing the central connection method of rubber products with the production cost.Compared with zinc oxide alone, besides the above advantages, the following advantages are obvious:

1. T10 long, T90 short; improve the coke time of mixed rubber; improve the processing safety of mixed rubber; shorten the curing time; improve the production efficiency.

2. Function of NBR anti - aging agent

3. Oil resistant function

4. Physical function of vulcanizate

5. Significantly reduce the cost of rubber materials, high yield and benefit.
