[0002] The main component of PVC is polyvinyl chloride, which is slightly yellow and translucent, shiny, better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene. Whitening will occur at the inflection point. Since the thickness of the PVC film is very small, wrinkles will often appear during the manufacturing process, which will affect the later use effect, so a PVC film flattening device is needed for processing.
