Basic characteristics of PVC

The density of pure polyvinyl chloride is 1.4 g/cm3, and the density of polyvinyl chloride plastic parts to which plasticizers and fillers are added is generally 1.15-2.00 g/cm3.

Hard PVC has good tensile, flexural, compressive and impact resistance properties and can be used alone as a structural material.

The softness, elongation at break, and cold resistance of the soft polyvinyl chloride increase, but the brittleness, hardness, and tensile strength are lowered.

Polyvinyl chloride has good electrical insulation properties, can be used as a low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCl gas, and discolor the polyvinyl chloride. Therefore, its application range is narrow, and the use temperature is generally between -15 and 55 degrees.

PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other types of plastic products, PVC is more effective in the application of raw materials, reducing fuel consumption. At the same time, the energy consumption of the PVC manufacturing industry is also very low. And in the later stages of the use of PVC products, it can be recycled and converted into other new products or incinerated to obtain energy.
