In 1898, a German chemist accidentally discovered a synthetic polyethylene polymer material in an experimental accident, which opened the prelude to the research on polyethylene polymer materials, and also gave birth to polyethylene polymer-based materials. Research on insulation and sheathing of wire and cable. Polyethylene material is the polymer with the simplest structure and the most widely used polymer material. Polyethylene is formed by addition polymerization of ethylene (CH2=CH2). The performance of polyethylene depends on its polymerization method. It is high-density polyethylene (HDPE) that is polymerized under medium pressure (15-30 atmospheres) and organic compound catalyzed conditions. The polyethylene molecules polymerized under this condition are Linear, and the molecular chain is very long, the molecular weight is as high as hundreds of thousands. If it is free radical polymerization under high pressure (100-300MPa), high temperature (190~210°C) and peroxide catalysis, low density polyethylene (LDPE) is produced.
Later, it was found that the high temperature resistance and aging resistance of crosslinked polyethylene materials were several times higher than those of uncrosslinked polyolefin materials, so this developed the subsequent physical crosslinking, chemical crosslinking, and warm water crosslinking. A study of perceptual polyethylene materials. In 2002, 3F introduced electron accelerators from Russia for physical irradiation crosslinking and research on polymer materials.3F polyethylene insulated high-temperature wires use physical irradiation crosslinking to change the structure of polymer molecular chains, promote crosslinking of polyolefin materials, and then form new molecular chain network structures. Insulated wires with cross-linked polyolefin insulated high-temperature wires have a wide range of applications.
