Sinopec PVC S700 is a high-quality suspension polyvinyl chloride (PVC) resin produced using advanced ethylene-based technology. As a medium-low polymerization grade, it is developed for applications requiring excellent processability, good transparency, stable thermal performance, and high-quality surface finish.

Supplied as a white free-flowing powder, S700 features uniform particle distribution, low impurity content, minimal fish-eye levels, and low volatile matter. Its relatively low K-value enables rapid plasticization and efficient melt flow, supporting reliable performance in extrusion, calendaring, and injection molding applications. The resin is widely used in transparent rigid sheets, packaging materials, PVC fittings, industrial sheets, semi-rigid films, and other processed PVC products.

Product Features of Sinopec PVC S700

  • Excellent Processing Fluidity. Sinopec S700 features a balanced molecular structure and relatively low polymerization degree, providing excellent melt flow properties during extrusion, calendaring, and injection molding processes. This helps reduce processing torque, improve production efficiency, and facilitate the molding of complex product structures.
  • Superior Transparency. With low fish-eye content, minimal impurities, and consistent particle morphology, Sinopec PVC S700 enables the production of PVC products with excellent transparency and visual appearance. It is especially suitable for transparent packaging sheets, folding box materials, and clear rigid applications.
  • Stable Thermal Processing Performance. The resin demonstrates reliable thermal stability during processing, minimizing discoloration and degradation at elevated temperatures. This contributes to improved product consistency and lower production scrap rates.
  • Outstanding Surface Quality. This product offers high whiteness and uniform particle characteristics, resulting in finished products with smooth surfaces and excellent gloss. It is ideal for applications where appearance quality is critical.
  • Reliable Mechanical Properties. Despite its medium-low polymerization degree, S700 delivers good rigidity, dimensional stability, and chemical resistance, meeting the requirements of a wide range of industrial and commercial applications.

Typical Applications

  • Transparent Sheets & Packaging Materials. S700 is widely used in transparent PVC rigid sheets, thermoforming sheets, folding box materials, and various packaging applications. Its excellent clarity and surface finish help enhance product appearance and packaging quality.
  • Calendared Films & Semi-Rigid Sheets. The resin is suitable for PVC calendared films, decorative films, stationery films, and semi-rigid industrial sheet applications, offering stable processing and consistent product quality.
  • Injection Molded Products. With excellent melt flow performance, Sinopec S700 is commonly applied in PVC injection molding products such as pipe fittings, connectors, valves, electrical housings, industrial components, and household products.
  • Rigid Boards & Profiles. PVC S700 can also be used for industrial boards, advertising sheets, rigid panels, and certain profile extrusion applications requiring dimensional stability and mechanical strength.
  • PVC Containers & Industrial Products. The resin is suitable for manufacturing PVC containers, industrial packaging boxes, corrosion-resistant products, and various general-purpose industrial components.
