The two have different purposes

　　1、PVC

It is used to make door and window materials, and its application still has a large growth in the range. Profile and profile are the category of PVC consumption in China, accounting for about 25% of the total PVC consumption. PVC is mixed with stabilizers, lubricants and fillers. After mixing, hard pipes, special-shaped pipes and corrugated pipes of various diameters can be extruded by extruder, which can be used as downcomers, drinking pipes, wire sleeves or stair handrails.

Into various corrosive storage tanks, air ducts and containers. The calendered sheets can be stacked and hot pressed to make hard plates of various thicknesses. The plate can be cut into the required shape, and then PVC welding rod is used to form various storage tanks, air ducts and containers with hot air.

It can be applied to the solid ground of airport terminal building and other places. Polyethylene wall panels are primarily used to replace aluminum wall panels. Except for a part of polyethylene resin, other components of polyethylene floor tiles are recycled materials, adhesives, fillers and other components.

2. Plastic

Plastics that can be used as engineering structures. It can bear certain external force and has good mechanical function, such as polyamide, polysulfone, etc. In engineering plastics, it is divided into general engineering plastics and special engineering plastics.

Plastic refers to the plastic that has a function and can be used in other special application areas. For example, plastics and silicon have functions, while plastics and foamed plastics have special functions such as cushioning.
