How To Distinguish The Type Of PVC
- Jul 12, 2018 -

PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used for the surface of floors, ceilings and leather, but because soft PVC contains plasticizer (this is also the difference between soft PVC and hard PVC), the physical properties are poor (such as the water pipe needs to withstand a certain water pressure, soft PVC It is not suitable for use), so its scope of use has been limited. Hard PVC does not contain plasticizers, so it is easy to form and has good physical properties, so it has great development and application value. In the production process of PVC materials, it is bound to add several additives, such as stabilizers, plasticizers, etc. If all environmentally friendly additives are used, PVC pipes are also non-toxic, tasteless and environmentally friendly.
