Advantages of zinc oxide for rubber:

1. Zinc oxide for rubber has small particle size and large surface area, so it has very strong activity.

2. Zinc oxide for rubber can improve the degree of crosslinking and the mechanical properties of vulcanized products. In addition, the modulus, tear resistance and friction resistance can be improved.

3. Since the zinc oxide particles for rubber have an active agent as the core, they form a porous form after polymerization, so they have good dispersibility.

4. The vulcanized product containing active zinc oxide is anti-aging, and it is not easy to crack when bent.

5. Zinc oxide for rubber does not affect the color of vulcanized products. In fact, it can make ivory or light-colored rubber products resist strong sunlight.

6. Since the refractive index of zinc oxide for rubber is similar to that of natural rubber, it can make the color of the vulcanized product more clear and transparent.

7. It can reduce mixing costs and improve chemical reaction efficiency.
