The electrical properties of sheet polyvinyl chloride produced by blister machine

Polyvinyl chloride is a polar polymer and has a high affinity for conductive substances such as water, so its resistance is lower than that of non-polar polyolefins, but it still has a higher volume cathode and breakdown voltage. The polar group of polyvinyl chloride is directly attached to the main chain. Below the glass transition temperature, the dipole segment is restricted by the main chain atoms of the frozen structure and cannot move, so it does not produce dipolarization. It can be used at room temperature. high-frequency insulating material. When used for wire insulation, the electrical insulation of the suspension resin is 10-100 times higher than that of the suspension resin. The presence of chloride ions from degradation reduces electrical insulation.
