EPDM, carbon black, paraffin oil, calcium carbonate, zinc oxide, stearic acid, accelerator, sulfur and others.
1. What is the function of carbon black? Reinforcing effect, which improves the physical properties of the product such as elastic recovery, tensile strength, compression deformation, tearing strength, etc., and protects the product from aging.
2. What is the function of paraffin oil? Used to adjust the hardness, lubricant and activator of products, and improve the low temperature resistance and aging resistance of rubber products.
