In daily life, we often see
PVC raincoats and some products made of PVC as pipes, packaging boxes, etc., which are used in all walks of life and are widely used. So what are the characteristics of this material?
Basic Features:
1. PVC is 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 period of use of PVC products, it can be recycled and converted into other new products or incinerated to obtain energy.
2. Rigid PVC has good tensile, bending, compression and impact resistance, and can be used alone as a structural material.
3. Soft PVC has better flexibility, elongation at break, and cold resistance will increase, but brittleness, hardness, and tensile strength will decrease.
4. PVC has good electrical insulation properties, can be used as low frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of PVC, long-term heating will cause decomposition, release HCL gas, and discolor PVC, so its application range is narrow, and the operating temperature is generally between -15 and 55 degrees.
