The density of pure polyvinyl chloride is 1.4g / cm & sup3, and the density of polyvinyl chloride plastic parts added with plasticizers and fillers is generally 1.15-2.00g / cm & sup3.
Rigid PVC has good tensile, bending, compression and impact resistance, and can be used alone as a structural material.
Soft PVC will increase in flexibility, elongation at break, and cold resistance, but brittleness, hardness, and tensile strength will decrease.
Polyvinyl chloride has good electrical insulation properties, can be used as low-frequency insulation materials, 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 change the color of polyvinyl chloride, so 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 uses raw materials more effectively and reduces fuel consumption. At the same time, the energy consumption of PVC manufacturing is also very low. And in the later stage of use of PVC products, it can be recovered and converted into other new products or incinerated to obtain energy.
