Key Features and Benefits
✅ Low Viscosity for Easy Processing
PVC SG8 exhibits low melt viscosity, making it ideal for injection molding and extrusion processes. It allows for smooth flow, faster production cycles, and consistent quality in finished goods.
✅ High Bulk Density and Thermal Stability
Its high apparent density provides better filler absorption and efficient compound mixing, while its thermal stability ensures minimal degradation during processing.
✅ Superior Mechanical Properties
With a K-value near 68, SG8 offers enhanced rigidity, impact strength, and abrasion resistance, making it suitable for high-stress applications such as pressure pipes and heavy-duty fittings.
Common Applications of PVC SG8
-
PVC Pressure Pipes and Fittings
Widely used in water distribution and sewer systems due to its strength and chemical resistance. -
Window Profiles and Doors
Ideal for producing rigid frames with excellent weatherability and thermal insulation. -
Sheets and Panels
Suitable for signage, construction, and industrial use where durability is key. -
Electrical Conduits and Cable Trays
Offers flame resistance and insulating properties essential for safe cable management. -
Automotive and Packaging Components
Used in producing automotive trims, protective covers, and sturdy packaging films.
Packaging and Storage
PVC SG8 is typically packaged in 25 kg bags or 1-ton jumbo bags and should be stored in a dry, cool, and well-ventilated area, away from direct sunlight and moisture. Proper storage prevents agglomeration and degradation of the resin.
