PVC SG-3 is mainly used to produce general-purpose soft products such as films, hoses, leather, wires and cables.
PVC SG-5 is suitable for manufacturing pipes, pipe fittings, plates, calendared products, injection-molded products, profiles and sandals.
PVC SG-7/SG-8 is often used to produce bottles, sheets, calendared products, hard injection and molded pipes, etc.
SG3: Leather, hoses, wire cables, shoes and other general-purpose soft products.
SG5: Pipes, profiles, fittings, panels, injection molding, sandals, hard tubes and decorative materials.
SG7 and SG8: Sheets, bottles, calendaring, rigid injection molding and molded pipes.
Good chemical stability: The resin has high chemical resistance, water resistance and wear resistance, and is not easily corroded by general chemicals. It can be used in a variety of chemical environments.
Good insulation: It is non-conductive and can be used as an insulating material for wires and cables, which can effectively ensure the safety of electricity use.
Thermoplasticity: Xinfa PVC can be softened by heat and hardened after cooling. It can be made into plastic products of various shapes through processing methods such as molding, calendaring, injection molding, extrusion, calendaring and blow molding.
Good mechanical properties: Rigid PVC has good mechanical strength and can be used to manufacture products such as pipes, doors and window profiles that require strength.
Flame retardancy: The resin has a certain flame-retardancy and is easy to extinguish after leaving the flame, which improves the safety during use.
