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 and can be used as a low-frequency insulation material. Its chemical stability is also good. Due to the poor thermal stability of PVC, long-time heating will cause decomposition, release HCL gas, and make PVC. Discoloration, so its application range is narrow, the use temperature is generally between -15 ~ 55 degrees.
PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other kinds of plastic products, PVC is more effective in applying raw materials, reducing fuel consumption, and at the same time, PVC. The energy consumption of the 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.
