Kunshan PVC pipe (full name Polyvinylchlorid), for the polyvinyl chloride, and other ingredients to enhance its heat resistance, toughness, ductility and so on. The surface of the film is the uppermost layer, the middle of the main component is polyvinyl chloride, the bottom layer is the back coating adhesive. It is the world's favorite, quite popular and has also been widely used as a synthetic material

Pvc pipe to the water pipe temperature, PVC pipe that is mainly the density of pvc and the size of the melt activity rate, and also with the type and performance of injection molding machine, a plastic part of the shape. Since pvc is a crystalline polymer, in the melting of the grain to absorb a certain amount of heat, so the barrel temperature should be higher than its melting point 10 ℃. For pvc, the barrel temperature control in the 140-200 ℃, HDPE barrel temperature control at 220 ℃, take the minimum barrel, the front end to take the maximum.
