What are the uses of plastics at all levels?

① polyvinyl chloride (PVC)

This is the most used plastic in buildings. Rigid PVC has a density of 1.38 ~ 1.43g/cm3, high mechanical strength and good chemical stability, and its service temperature is generally between-15 ~+55℃, so it is suitable for manufacturing plastic doors and windows, sewer pipes, trunking, etc.

② Polyethylene

Polyethylene plastic is mainly used for water supply and drainage pipes and sanitary ware in buildings.

③ Polypropylene (PP)

The density of polypropylene is the smallest of all plastics, about 0.90. Polypropylene is usually used to produce building products, such as pipes and sanitary wares.

④ Polystyrene

Polystyrene is a colorless and transparent glassy plastic. Polystyrene is mainly used to produce foam insulation materials, light-transmitting materials and other products in buildings.
