The properties and uses
of PVC resin SG5 in the field of chemical production raw materials
1. Introduction

PVC(Polyvinyl Chloride) resin is a widely used plastic material with excellent physical and chemical properties. Among the many varieties of PVC resin, SG5 is a commonly used model. This article will detail the properties and uses of PVC resin SG5.

2. the properties of PVC resin SG5

1. Physical properties: PVC resin SG5 is a white or light yellow powder with a high density, usually between 1.35-1.45g/cm³. Its melting point is between 130-210°C, and it has high heat resistance and cold resistance.
2. Chemical properties: PVC resin SG5 has good chemical resistance and can resist the corrosion of many acids, alkalis and salts. In addition, it also has excellent flame resistance, weather resistance and electrical insulation.

3. The use of PVC resin SG5

1. Building materials: PVC resin SG5 has a wide range of applications in the field of building materials, such as pipes, door and window frames, wall panels, floors, etc. Due to its excellent weather resistance and chemical resistance, it has a long service life in the construction field.
2. Wire and cable: PVC resin SG5 has good electrical insulation, so it is widely used in wire and cable manufacturing. It can protect the wire from the external environment and extend the service life of the wire.
3. Packaging materials: PVC resin SG5 can be made into films, bottles, boxes and other packaging materials for packaging various commodities. Because of its excellent chemical resistance and flame resistance, it has a high value in the field of packaging.
4. Auto parts: PVC resin SG5 can be used to manufacture interior and exterior parts of automobiles, such as steering wheels, seats, door panels, etc. Because of its excellent heat resistance, cold resistance and chemical resistance, it has a wide range of applications in the field of automobile manufacturing.

4. conclusion

PVC resin SG5, as a common chemical raw material, has excellent physical and chemical properties, so it is widely used in the fields of construction, wire and cable, packaging and automobile manufacturing.
