Polarity of the PVC, hardness and rigidity of the larger than normal polyethylene, high dielectric constant and dielectric loss ... all the way to the glass transition temperature (80 degrees), the performance remained unchanged, proof PVC dipole is very stable, resistant to acids and alkali erosion.

About 9.7 solubility parameters of PVC, non-polar solvent solubility parameters of resistance is low,Soluble in certain ketones, esters and chlorinated hydrocarbons whose molecules contain a lot of chloride, give it a good flame retardant, but due to the introduction of plasticizer, reducing flame.
