What is EPDM?Ethylene propylene rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene, and is a kind of ethylene propylene rubber.
For EPDM rubber, where E represents ethylene, P represents propylene, D is a diene, and M is a classification of D-1418 in the ASTM standard.
What are the advantages of EPDM rubber?
1) Excellent aging resistanceFirst of all, from the molecular formula of the entire EPDM rubber, its main chain is composed of chemically stable saturated hydrocarbons, only unsaturated double bonds are contained in the side chain, and the proportion of unsaturated double bonds is very low. Its performance is very stable. Its carry excellent technical performance which include ozone resistance, heat resistance, weather resistance and other aging resistance. It can be used outdoors for a long time to ensure its performance. Therefore, many industries use its aging resistance to make products for use. Widely used in the fields of automotive parts, automotive seals, wire and cable jackets, tapes, etc.
EPDM rubber has a density of 0.87, and it can add a large amount of filler oil and filler. Usually the cost of these filler oil and filler is much lower than the price of ethylene-propylene rubber raw rubber, so it can reduce the cost of rubber products. In terms of performance for EPDM rubber with high Mooney value, the physical and mechanical energy will not decrease much after high filling.
The molecule of EPDM rubber is essentially non-polar, the proportion of unsaturated bonds is very low, and it has good resistance to polar solutions and chemicals.
The above briefly introduces the advantages of EPDM rubber. It is precisely because of these advantages that when used outdoors, it is often the preferred raw material for rubber products. The cold-shrinkable tubes produced by our company are also made of EPDM rubber material.
