EPDM ”这种橡胶材料相信大家都不会陌生,这种广泛应用于汽车橡胶配件 ,的材料已经深入到我们生活当中的方方面面,那么对于这种材料您真的了解了吗? I believe that the rubber material " EPDM " in silicone rubber products will be familiar to everyone. This material, which is widely used in automotive rubber parts , has penetrated into every aspect of our lives. So do you really know this material?

EPDM

中文名:三元乙丙橡胶英文全称 :Ethylene-Propylene-Diene Monomer( 简称 :EPDM) ,三元乙丙橡胶是乙烯、丙烯以及非共轭二烯烃的三元共聚物, 1963 年开始商业化生产。 EPDM Chinese name: EPDM rubber full name in English : Ethylene-Propylene-Diene Monomer ( abbreviation : EPDM) , EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated diolefins, commercialized in 1963 produce. 80 万吨。 Annual consumption worldwide is 800,000 tons. 最主要的特性就是其优越的耐氧化、抗臭氧和抗侵蚀的能力。 The main feature of EPDM is its superior resistance to oxidation, ozone and erosion. (PA66) 烃家族,它具有极好的硫化特性。 Since EPDM rubber belongs to the polyolefin (PA66) hydrocarbon family, it has excellent vulcanization characteristics. EPDM 具有最低的比重。 Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of fillers and oils without affecting the characteristics. Therefore, a low-cost rubber compound can be produced.

  Vulcanization type

EPDM can be vulcanized with organic peroxide or sulfur. However, compared with sulfur vulcanization, peroxide-crosslinked ethylene propylene has higher temperature resistance, lower compression set and improved vulcanization characteristics when used in the wire and cable industry. The disadvantage of peroxide curing is higher costs.

Secondly, EPDM rubber has good air tightness, excellent ozone resistance, aging resistance and heat resistance, and has been widely used in automotive rubber fields, such as: automotive antenna waterproof gaskets , automotive wiring harness bellows , door and window seals. , Shock pads and more. Of course, individual models may differ due to different physical properties of the formula.
