FAQ

The main differences between PVC Resin SG3, SG5, and SG8 are in their molecular weight and viscosity, which affect their processing and application:

  • SG3: This grade has the lowest molecular weight and is characterized by high plasticity and low viscosity. It is suitable for soft and flexible applications such as plastic films, artificial leather, and electrical insulation.
  • SG5: This is a medium molecular weight grade with balanced properties, making it the most versatile. It is commonly used in a wide range of applications, including pipes, fittings, and rigid profiles. SG5 offers good processability and mechanical properties.
  • SG8: This grade has the highest molecular weight, resulting in high rigidity and strength. It is ideal for applications requiring robust mechanical properties, such as pipes, fittings, and injection-molded products. SG8 provides excellent durability and chemical resistance.

 PVC Resin – SG5 is a medium molecular weight grade of PVC resin, known for its balanced properties and versatility. Its primary applications include:
