Uv radiation crosslinked polyethylene insulating material

Crosslinked polyethylene is widely used in wire and cable, heat shrinkable material, hot water pipe and foam material. Commonly used in industry polyethylene crosslinking methods mainly include high-energy radiation crosslinking (gamma rays, electron beams, neutron beams, etc.) and chemical crosslinking (peroxide method and silane method). The main disadvantages of high energy radiation crosslinking are huge investment, complicated process control, and large dedicated workshop. Uv crosslinking law technology equipment is simple, less investment; Easy to operate and maintain; High energy efficiency, no pollution to the environment; Low operating cost, safety protection requirements are not harsh; Light radiation damage is small, mechanical and electrical properties are excellent.
However, due to two major obstacles, the penetration ability of ultraviolet light and the low speed of photoinduced crosslinking of polyethylene, the crosslinking method has not been widely applied in industry for decades.
