Due to a series of advantages of high chlorinated polyethylene rubber (CPE), such as heat and oil resistance, ozone resistance and atmospheric aging resistance, it has been widely used in wires and cables abroad, especially sheath materials. In China, as early as the early 1990s, when Weifang Chemical Plant introduced the second largest CPE production line into operation, Shanghai Cable Research Institute, as the national cable industry technology development center, held a second CPE application technology exchange meeting. At that time, it was proposed that because of the similar performance of CPE and CR, CR should be used as an alternative material in the cable industry. Use. However, in recent years, it has encountered problems in market, technology, equipment, standards and so on, which limits the promotion and application of CPE materials in wires and cables. In addition, the unstable quality of domestic CPE products, small scale of production, insufficient supply of goods and other factors also restrict its application in the wire and cable industry.

At present, due to the shortage of common neoprene supply and the rising price, the cost of products increases. In addition, foreign standards clearly stipulate that chloroprene rubber cable products are not allowed to be used in certain specific occasions. So it is a matter of time for CPE to replace CR. At present, there are many domestic wire and cable manufacturers in the research and development and application of high chlorinated polyethylene, and successful application of manufacturers.
