The properties and uses of ethylene-propylene rubber play an important role in the field of raw materials for chemical production. Ethylene-propylene rubber is a copolymer of ethylene, propylene and non-conjugated diene. It has excellent oxidation resistance, ozone resistance, corrosion resistance and aging resistance. In this paper, the properties and uses of ethylene propylene rubber are discussed in detail.

1, the nature of ethylene propylene rubber

1. oxidation resistance: ethylene propylene rubber molecular structure of the non conjugated diene units, so that it has a high resistance to oxidation, can be in high temperature, high pressure oxidation environment to maintain stability.
2. Anti-ozone performance: Ethylene propylene rubber has good anti-ozone performance, can maintain good elasticity in the environment with high ozone concentration, and is not easy to crack.
3. anti erosion performance: ethylene propylene rubber has good anti erosion performance, can resist the erosion of acid, alkali, salt and other chemical substances, not easy to occur chemical corrosion.
4. anti-aging properties: ethylene propylene rubber has good anti-aging properties, can be used in the natural environment for a long time without significant performance degradation.

II.
of the use of ethylene-propylene rubber
ethylene-propylene rubber has been widely used in the field of chemical production raw materials due to its excellent performance. The following are some of the main uses:

1. Automotive industry: ethylene propylene rubber is widely used in the automotive industry, used in the manufacture of automobile sealing strips, tire inner tubes, airbags and other parts. Its oxidation resistance, ozone resistance, corrosion resistance and anti-aging properties make auto parts have a long service life and good performance.
2. construction industry: ethylene propylene rubber in the construction industry for the manufacture of waterproofing membrane, sealing materials. Its excellent weather resistance and aging resistance make the building material have a long service life and good waterproof performance.
3. Wire and cable industry: Ethylene propylene rubber is used in the wire and cable industry to manufacture cable sheaths, insulation materials, etc. Its oxidation resistance, corrosion resistance and aging resistance make the wire and cable have a long service life and good insulation performance.
4. Petrochemical industry: Ethylene propylene rubber is used in the petrochemical industry to manufacture corrosion-resistant pipes, valves, etc. Its excellent erosion resistance makes the equipment have a long service life and good operating performance.

In short, ethylene-propylene rubber has a wide range of applications in the field of chemical production raw materials due to its excellent performance, and provides important material support for products in various fields.
