Main Applications of Sinopec PVC S-1300

  • In the wire and cable industry, it is commonly applied in cable insulation and sheathing, providing excellent electrical protection, mechanical strength, and long-term safety.
  • For rigid and semi-rigid products, Sinopec PVC S-1300 is suitable for manufacturing industrial and household molded parts as well as structural plastic components that demand high strength and dimensional stability.
  • In films, sheets, and calendered products, this grade is used to produce high-strength PVC films, transparent and semi-transparent sheets, and various soft or semi-rigid calendered materials with good surface quality and mechanical performance.
  • Additionally, PVC Resin S-1300 is widely applied in synthetic leather and flexible products, including artificial leather, flexible hoses and tubing, coated fabrics, and soft PVC sheets, where a balance of strength, flexibility, and durability is required.

Performance Advantages

  1. High Mechanical Strength. The high molecular weight of PVC S-1300 provides superior tensile strength, hardness, and resistance to deformation, making it suitable for applications requiring structural integrity.
  2. Excellent Electrical Insulation. Sinopec S-1300 offers reliable dielectric properties, making it an ideal material for wire and cable insulation and sheathing applications.
  3. Good Chemical and Weather Resistance. Products made from S-1300 maintain stable performance in various chemical environments and under long-term outdoor exposure when properly formulated.
  4. Broad Processing Adaptability. The resin can be processed by extrusion, calendering, injection molding, and other conventional PVC processing methods with appropriate formulation control.

Processing Recommendations

  • Due to its high degree of polymerization, PVC S-1300 requires proper control of processing temperature and shear to ensure complete plasticization and avoid thermal degradation.
  • Appropriate selection and dosage of plasticizers, stabilizers, and lubricants are recommended to optimize processing performance and end-product properties.
  • Suitable for both rigid and flexible PVC formulations depending on additive systems.
