Problems solved by technology

[0002] At present, rubber cable conductor shielding materials generally use halogen-containing materials, such as neoprene and chlorinated polyethylene. These materials will decompose under high temperature conditions to produce corrosive hydrogen chloride gas, which will cause damage to conductors and insulating materials, especially in the event of a fire. Combustion will produce toxic gas with pungent smell, which directly threatens the safety of human life and causes immeasurable losses to people's lives and property
[0003] In order to improve the safety and environmental protection of cables, there are also some halogen-free elastomers, such as nitrile rubber and ethylene-vinyl acetate copolymer, but these materials have poor processing performance and high temperature resistance, and can only be used under normal temperature conditions. , can not meet the needs of some special purposes
