As a manufacturer of silicone rubber cable and wire, you will face customers with different needs. Sometimes customers ask why the silicone wire cannot meet the requirements of low smoke and halogen-free. Today Xiongxin is going to briefly explain why silicone electrical wire cannot meet the halogen-free standard.
We know that silicone rubber wire has excellent properties, such as high and low temperature resistance, good flexibility, acid and alkali resistance. But as environmental protection becomes more and more important, the standards for halogens are getting stricter. So when customers choose electronic cables, they often ask for low smoke and halogen-free. However, silicone rubber wires are generally unable to meet this standard.
Because silicone rubber wire is made by extruding a conductor (tinned or bare copper) and an insulating material (silicone rubber), the insulating material itself contains traces of halogens. During the manufacturing process, silicone rubber wires are vulcanized, and the vulcanizing agent used in this process is halogenated, resulting in silicone rubber wires that end up with some halogen.
But as technology continues to evolve, silicone rubber wires have moved in the direction of low smoke and low-halogen. In the near future, low smoke and halogen-free will be a criterion for silicone rubber cable and wire manufacturers.
