PVC film can be seen in many common molded products or products containing films. This form of plastic is actually similar to polyethylene, but its ductility and plasticity are relatively strong. Hard PVC can be used in pipes, buildings, and some plastic hard products. The main form of soft PVC is a film. PVC films can be added to the plastic wrap we use and the reflective film on automotive glass. It is a plastic material with wide application range and strong effect. Whether it is a rigid form of PVC or other forms of PVC, they are all examples of PVC plasticity, which also shows that this material has good ductility. If Sun Wukong's gold hoop can be long or short, then PVC is a material that can be hard or soft and has a wide range of uses. ????Such a material, why there are two completely different forms of hardness and appearance, this is mainly determined by the amount of plasticizer added, the general hard PVC is added with less than 5 parts of plasticizer The measurement is formed, and the soft form of the pvc film or pvc transparent film is added with more than 25 parts of the measurement, so such two extreme forms of pvc appeared, this is also a major discovery of plastics, and it is also possible for plastics to become The main factor of mainstream packaging materials in the city.
