General EPDM rubber seals are suitable for sanitary equipment, automotive radiators and automotive brake systems. EPDM rubber is a terpolymer of ethylene, propylene, and non-conjugated diene. Commercial production began in 1963. The main characteristic is its superior resistance to oxidation, ozone and erosion.

三元乙丙橡胶密封圈 有些优点呢? So, what are the advantages of EPDM rubber seals ?

① The best aging resistance. This is one of the most significant characteristics of EPDM rubber. Its aging resistance is not only much better than ordinary rubbers such as styrene-butadiene rubber, natural rubber, neoprene, but also better than butyl rubber generally considered to have good aging resistance. Base rubber.

②Excellent chemical stability. During the long-term contact with various polar chemicals, its performance changes are small.

③ It has excellent resistance to permanent compression and relaxation of compression stress. 压缩永久变形很小、应力松弛特别缓慢。 EPDM rubber seals have very small compression set and very slow stress relaxation. Its compression deformation resistance is also superior to other ordinary rubbers.

④ Has high flexibility. In general rubber, its elasticity is second only to natural rubber and butadiene rubber, and higher than other ordinary rubbers. 三元乙丙橡胶密封圈 使用寿命比普通橡胶圈有根本的提高。 According to relevant information, the service life of EPDM rubber seals has been substantially improved compared to ordinary rubber seals . 30~50年的情况大不相同,在同样的使用环境(即埋深在0.5~3.0m,其环境温度为18~22℃)下,经过计算 三元乙丙橡胶密封圈 正常使用寿命为 110年,注重按规范施工, 三元乙丙橡胶密封圈 能匹配球墨铸铁管 70~100年的运行寿命,使管网的运行安全得到根本保障。 Compared with the normal service life of ordinary rubber rings currently used for 30 to 50 years, it is very different. Under the same operating environment (that is, the buried depth is 0.5 to 3.0 m and the ambient temperature is 18 to 22 ° C), after calculation The normal service life of EPDM rubber seals is 110 years. Emphasis on construction according to specifications. EPDM rubber seals can match the operating life of ductile iron pipes from 70 to 100 years, which guarantees the safety of pipe network operation.

因其优良的性能,它被我们更广泛地运用在生活以及工业中。 EPDM rubber sealing ring is widely used in our life and industry because of its excellent performance. Haisheng Rubber has certificates such as TS16949, REACH, professional custom rubber seals, and a team of professional engineers tailored for you. Welcome to the official website for consultation
