EPDM is a general-purpose synthetic rubber used in corrosive gas or liquid pipelines. It is produced from ethylene and propylene as raw materials.The main performance advantages of EPDM rubber are as followsExcellent aging resistance, resistance to ozone, sunlight, heat, water vapor, UV rays, radiation, etc.The main chain of its molecular structure does not contain double bonds, and it has high chemical stability, excellent electrical insulation properties and water resistance.EPDM rubber has heat resistance and its saturation is very low, so it can more effectively reduce its oxidation reaction with oxygen, especially ozone.Anti-aging performance. The main reason for the aging of rubber and other products is oxidation reaction, followed by corrosion from other chemicals such as acids and alkalis, as well as damage caused by friction.It has good corrosion resistance. EPDM is a non-corrosive rubber with a very low saturation. It has strong tolerance to various acids, alkalis, animal and vegetable oils, refrigerants, etc. It can be used to transport weak acids, alkalis, refrigerants and other materials.It has high elasticity. Among general-purpose rubbers, its elasticity is second only to natural rubber and butadiene rubber, and higher than other common rubbers. It has very small compression permanent deformation, and its stress relaxation is particularly slow. Its compression deformation resistance is also better than other common rubbers.
