Description

technical field [0001] The invention relates to a cold-resistant, temperature-resistant, flame-retardant and surface migration-resistant polyvinyl chloride insulating material. Background technique [0002] At present, the comprehensive performance of the commonly used power cable is relatively common, and the grade is low. Generally, it does not have the comprehensive performance of low temperature embrittlement resistance, low temperature impact resistance, high temperature aging resistance, flame retardancy and surface migration resistance. It is not suitable for It is used in electrical, electronic and communication products that require flame retardancy and surface migration resistance in low temperature environment or high temperature environment. Due to the lack of medium and high-end varieties, there is an urgent need for innovative varieties in the field of mid-to-high-end power cables that are non-toxic and environmentally friendly, low temperature resistant, high ...
