PVC resin SG5 has a medium molecular weight and a degree of polymerization of approximately 1000-1200. This molecular structure endows SG5 with excellent physical and chemical properties, including outstanding mechanical strength, chemical corrosion resistance, and good thermal stability. SG5 has good electrical insulation, non flammable, low water absorption and good anti-aging ability. These features make SG5 perform well in various applications.

 

2.Main uses of PVC resin SG5

 

Building material

 

PVC resin SG5 is widely used in the manufacturing of building materials such as pipes, profiles, and sheets. Its excellent mechanical strength and corrosion resistance make PVC pipes occupy an important position in fields such as water supply, drainage, and cable protection. PVC profiles are widely used in door and window frames because of their good insulation performance, which can effectively reduce heat loss.

 

Packaging

 

PVC resin SG5 is also commonly used in the production of packaging materials, including films and hard packaging. The PVC film produced by SG5 has high transparency and good barrier properties, and is commonly used in food and pharmaceutical packaging. Hard packaging is commonly used for protecting the outer shells of electronic products and toys.

 

Wire and cable

 

Due to its excellent electrical insulation performance, SG5 is widely used as an insulation layer and sheath material for wires and cables. PVC cables have the characteristics of strong fire resistance, corrosion resistance, and stable mechanical properties, and are important materials in power transmission and communication lines.

 

Other applications

 

PVC resin SG5 is also used in the manufacturing of daily consumer goods such as toys, shoe soles, and medical devices. Its versatility and ease of processing enable it to meet the manufacturing needs of various products.
