The density of pure polyvinyl chloride is 1.4g/cm³, and the density of PVC plastic parts such as plasticizer and filler is generally 1.15-2.00g/cm³.
PVC has good tensile, flexural, compressive and impact resistance, and can be used as structural material alone.
The softness of soft PVC, elongation at break and cold resistance will increase, but brittleness, hardness and tensile strength will decrease.
PVC has better electrical insulating properties, can be used as low frequency insulating material, its chemical stability is good. Because of the poor thermal stability of PVC, long time heating will lead to decomposition, release HCL gas, so that PVC discoloration, so its application is narrow, the use of temperature in general-15~55度 between.
