What Is PVC? What Is PVC Plastics Material Used For?
Oct 17, 2023| 1.What is PVC plastic material ?
PVC plastic material is a polymer polymerized by vinyl chloride (VCM) monomer through initiators such as peroxides and azo compounds or under the action of light and heat according to a free radical polymerization reaction mechanism.Then it is processed into various products. According to the amount of plasticizer added, it is divided into rigid PVC and soft PVC.
1.1 What is soft PVC?
Soft PVC is generally used for floors, ceilings, and the surface of leather. However, because soft PVC contains softeners (this is also the difference between soft PVC and hard PVC), it easily becomes brittle and difficult to preserve, so the scope of application has certain limitations.
1.2 What is rigid PVC?
Rigid PVC is mainly used for construction pipes, doors, windows, and profiles. It does not contain softeners, has good flexibility, is easy to shape, not brittle, non-toxic and non-polluting, and has a long storage time, so it has high application value.

2. The difference between PVC and PE
The transparency of PVC film is higher than that of polyethylene, and the products are brightly colored, smooth to the touch, without a waxy feeling, and a special smell can often be smelled; it becomes obviously hard when exposed to cold, and the use temperature is 60°C; the relative density is greater than 1 and can sink in Under water, this is the distinguishing feature of PVC; hard products are hard and smooth, and the sound is muffled when struck; soft products are soft and elastic. PVC cannot be used to package food.
3. Properties of PVC
- Light weight, easy to transport and load: PVC pipe material is very light, convenient for transportation, loading and unloading, and construction, and saves labor.
- Excellent chemical resistance: PVC pipe has excellent acid resistance, alkali resistance, and corrosion resistance, and is very suitable for use in the chemical industry.
- Small flow resistance: The wall surface of PVC pipe is smooth, the fluid resistance is small, and its roughness coefficient is only 0.009, which is lower than other pipes. Under the same flow rate, the pipe diameter can be reduced.
- High mechanical strength:PVC pipes have very high water pressure resistance, external pressure resistance, impact resistance.
- Good electrical insulation: Suitable for protective casing of wires and cables.
4. The use of PVC
- Pipes: PVC can be made into polyvinyl chloride pipes, such as drainage pipes, water supply pipes, electrical wire pipes, etc.
- PVC film:Films made by mixing PVC with other additives can be cut to process packaging bags, raincoats, tablecloths, toys, etc.
- Packaging Materials: PVC can be made into laminates and transparent products with other polymers. For example, mineral water bottles, beverage bottles, cosmetic bottles.
- Hard materials and plates: PVC is then added with stabilizers and other fillers, and after mixing, various hard pipes, corrugated pipes, etc. can be extruded. It can also be pressed into thin sheets to make hard plates and cut into the required shape.
- Foam products: When PVC is mixed, a foaming agent can be added to make foam plastics, which can be used to make foam slippers, foam insoles, and shock-proof packaging materials.
