1. the property of NR
It has good wear resistance, high elasticity, breaking strength and elongation, But in the air, it is easy to get age, and it is get sticky when it get in touch with heat, which is easy to expand and dissolve in mineral oil or gasoline, but it is resistant to strong acid, but not to Alkali . working temperature is -50~70ºC.
2. the property of EPDM
Weather ability, aging resistance, ozone resistance, chemical stability are excellent, and CFCS and a variety of refrigerants. Working temperature is -50~150
3. the property of silicone
It has excellent heat resistance, cold resistance, ozone resistance and atmospheric aging resistant.Good electrical insulation performance,The tensile strength and wear resistance are generally poor and has non- oil resistant. The working temperature is -55~250ºC
4. The property of NBR
Good oil resistance, heat resistance, abrasion resistance, solvent resistance and high - pressure oil,But it is not suitable for polar solvents, such as ketones, ozone, nitro-hydrocarbons, and chloroform. The working temperature is -40~120 ºC
5. the property of CR
It has good elasticity, wear resistance and atmospheric aging resistance. It is not afraid of violent distortion and flammability.Chemical stability. The working temperature is -40~100 ºC
6. The property of FKM
Excellent high temperature resistance,And have excellent chemical resistance, most oil and solvent (other than ketones and esters).cold resistance is not good.
