Description: 

Polyvinyl chloride (PVC for short) is an important synthetic plastic material. According to different physical properties and chemical structures, it can be divided into the following categories: rigid PVC, flexible PVC, emulsion PVC and double-wall corrugated PVC.

Usage：

1. Rigid PVC: Rigid PVC is a hard plastic with high mechanical strength and chemical corrosion resistance. It is usually used to make building materials such as water pipes, drain pipes, window frames, door frames, floor tiles, and wire and cable protective covers.

2. Flexible PVC is a plastic with good flexibility and plasticity. Common applications include making wire and cable insulation layers, filling tubes, plastic bags, inflatable toys, medical devices, etc.

3. Emulsion PVC: Emulsion PVC is a PVC that uses water as a medium for polymerization. It has high adhesion and coatability and is widely used in coatings, adhesives, wallpaper and other fields.

4. Double-wall corrugated polyvinyl chloride (Double-wall corrugated PVC): Double-wall corrugated PVC is a pipe with a corrugated structure. It has high compressive resistance and corrosion resistance and is usually used in drainage systems, underground cable protection and other fields.
