(Ethylene Propylene Rubber) is made by the co-polymerization of ethylene and propylene, and therefore heat resistance, anti-aging resistance, ozone resistance, stability are very good. But sulfur cannot put into sulfur. In order to solve this problem, EP backbone introducing a small amount of a third component of the double-stranded and can add sulfur serve EPDM, the general temperature of -50 ~ 150 ℃. It has excellent resistance to polar solvents such as alcohols, ketones and so on.

Advantages:

1). good weather and ozone resistance;

2). excellent water resistance and anti-matter of the word;

3). you can use alcohol and ketones;

4). resistance high temperature steam;

5). with good gas impermeability;

Disadvantages:

1). not recommend to use for foods;

2). not recommend being exposed to aromatic hydrogen;

Applications:

1).the environment of high-temperature water vapor seals;

2). sanitary equipment seals or parts;

3). brake system rubber parts;

4). the seals of radiators;
