The main characteristics of EPDM for children are its excellent resistance to oxidation, ozone and corrosion. Since EPDM belongs to the polyolefin family, it has good vulcanization characteristics. Among all rubbers, EPDM has a low specific gravity. It can absorb a large amount of fillers and oils without affecting the characteristics. Therefore, low-cost rubber compounds can be made.

Characteristics

EPDM is a terpolymer of ethylene, propylene and non-conjugated dienes. Diene has a special structure, only one of the two bonds can be copolymerized, and the unsaturated double bond is mainly used as a crosslink. The other unsaturated will not become the main chain of the polymer, but only the side chain. The main polymer chain of EPDM is saturated. This feature makes EPDM resistant to heat, light, oxygen, and especially ozone. EPDM is essentially non-polar, resistant to polar solutions and chemicals, has low water absorption, and has good insulation properties.

In the production process of EPDM, its characteristics can be adjusted by changing the number of three monomers, the ethylene-propylene ratio, the molecular weight and its distribution, and the method of vulcanization.

It has outstanding aging resistance, electrical insulation and ozone resistance. EPDM can be filled with a large amount of oil and carbon black, and the product price is relatively low. EPDM has good chemical stability, and its wear resistance, elasticity and oil resistance are similar to those of styrene-butadiene rubber. EPDM has a wide range of uses. It can be used as tire side, rubber strips and inner tubes, as well as automobile parts. It can also be used as wire and cable sheaths and high-voltage and high-voltage insulation materials. It can also be used to make light-colored products such as shoes and sanitary products.
