PVC is widely used as a plastic raw material. In the process of use, PVC is divided into soft PVC and hard PVC. Soft PVC contains an additive, a softener, so the product is soft, easily brittle, cracked, and difficult to store.
The hard PVC does not contain softeners, so it has good flexibility, is not easy to become brittle and crack, and has a long service life.
According to your situation, when you buy, you should emphasize that you need products made of rigid PVC, so that you can meet the requirements for use.
The quality is good or bad, and it is easy to break. It is related to the filler it adds. The more fillers are added, the less PVC raw materials are used, the worse the quality is, and the easier it is to break.
