Analysis of four differences between PC material and PVC material 


1、 Different definitions.


PVC is also called PVC. The density of pure PVC is 1.4g/cm3. The density of PVC plastic parts with plasticizer and filler is generally 1.15-2.00g/cm3. UPVC has good tensile, bending, compression and impact resistance, and can be used as structural material alone. The softness, elongation at break and cold resistance of soft PVC will increase, but the brittleness, hardness and tensile strength will decrease. PVC has good electrical insulation performance, can be used as low frequency insulation material, its chemical stability is also good. Due to the poor thermal stability of PVC, long-time heating will lead to decomposition, release HCl gas and make PVC discolor, so its application range is narrow, and the service temperature is generally between - 15-55 ℃. PC is a kind of polymer containing carbonate group in molecular chain. According to the structure of ester group, PC can be divided into aliphatic group, aromatic group, aliphatic aromatic group and so on. Because of the low mechanical properties of aliphatic and aliphatic aromatic polycarbonates, their applications in engineering plastics are limited. Only aromatic polycarbonate has been industrialized. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastics among the five engineering plastics.


2、 Different materials


PC board generally refers to PC sunlight board and PC endurance board, PC wave tile and PC daylighting tile and PC synthetic resin tile. Sunlight board is hollow multi-layer or double-layer structure, endurance board is solid board. PVC board is a kind of vacuum plastic film, which is made of PVC with honeycomb mesh structure.


3、 The price is different


PVC is the most commonly used, and the price is cheaper than PC material.


4、 Different uses


PC can only do hard products, unlike PVC products, soft hardness can be arbitrarily adjusted.
