For PVC, many friends still have a lot of questions. I don’t know what material PVC is made of, and I don’t know whether it is hard or soft? What is the difference between hard pvc and soft pvc? Let us take these questions together to understand the relevant content together!
What is the material of pvc? Is it hard or soft?
It can be divided into hard PVC and soft PVC. The scientific name of pvc is polyvinyl chloride, which is the main component of plastic and is often used to make plastic products. It is cheap and widely used. The biggest difference is that they have different hardness. Hard PVC does not contain softener, which has high hardness and is easy to store, while soft PVC contains softener and has good softness.
What is the difference between hard pvc and soft pvc？
1. Different ingredients
Although their main raw materials are all pvc, they have some differences in composition. In the production of soft pvc, some softeners are added, which makes its finished product have good flexibility, good bendability, foldable in half, curlable, and easy to shape. Hard PVC does not add softeners in production, so it is not easy to shape, fragile, and cannot be curled.
2. Different applications
Due to its good flexibility, soft PVC can be used to make tablecloths, floors, ceilings, etc., while hard PVC is mainly used to make plastic boxes, PVC pipes, profiles, etc.
3. Different characteristics
From the point of view of characteristics, soft pvc has good stretch line, extensibility, high temperature resistance and low temperature resistance, so it can also be used to make transparent tablecloths. The operating temperature of hard PVC generally does not exceed 40 degrees. If the temperature is too high, hard PVC products may be damaged.
All in all, the main difference between soft pvc and hard pvc is their hardness. When we buy, we can distinguish them by their hardness and feel.
