Polyvinyl chloride (PVC) resin SG5 refers to a specific grade of PVC resin. PVC resin is a synthetic polymer produced from vinyl chloride monomers. It is widely used in various applications due to its versatility, durability, and cost-effectiveness.
The “SG5” designation for PVC resin indicates its K value or degree of polymerization. K value is a measure of the average molecular weight of the polymer. SG5 typically has a K value range of 65-68. The K value determines the physical and mechanical properties of the PVC resin, such as its viscosity, hardness, and processability.
PVC resin SG5 is commonly used in the production of rigid PVC products, including pipes, fittings, profiles, sheets, and films. It possesses good mechanical strength, chemical resistance, and electrical insulation properties. The resin can be modified with additives to achieve desired characteristics, such as impact resistance, weatherability, or flame retardancy.
