INTRODUCTION
EPDM is a terpolymer of ethylene, propylene and unconjugated diolefin. Diolefin has a special structure, only one of the two bonds can copolymerize, unsaturated double bonds are mainly used as cross-links. The other unsaturated one will not become the main chain of the polymerization, it will only become the side chain. The main polymer chain of EPDM is completely saturated. This property 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.
The most important characteristic of EPDM is its superior oxidation resistance, ozone resistance and erosion resistance. Epdm rubber belongs to the polyolefin family, it has excellent vulcanization characteristics. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a lot of fillers and oil without affecting the characteristics. This makes it possible to make rubber compounds at low cost.
In the production process of EPDM, the properties of EPDM can be adjusted by changing the number of three monomers, the ratio of ethylene to propylene, the molecular weight and its distribution, and the vulcanization method
PECULIARITY
1. Low density and high filling
2. Aging resistance
3. Corrosion resistance
4. Water vapor resistance
5. Resistance to excessive hot water
6. Electrical properties
Step 7 Be flexible
8. Adhesion
APPLICATION
Aging resistance, electrical insulation and ozone resistance are outstanding. Ethylene propylene rubber can be filled with oil and carbon black, the product price is low, ethylene propylene rubber chemical stability is good, wear resistance, elasticity, oil resistance and styrene butadiene rubber close. Ethylene propylene rubber has a wide range of uses, can be used as tire side, rubber strip and inner tube and auto parts, and can also be used as wire, cable sheath and high voltage, ultra-high voltage insulation material. Can also manufacture and shoes, hygiene products and other light-colored products.
