PVC resin, with the full name of polyvinyl chloride resin, is a kind of synthetic plastic polymer with large production volume each year. As a result, it is widely used in various plastic industrial fields. Polyvinyl chloride resin is a thermoplastic polymer compound formed by polymerization of vinyl chloride monomer(VCM) or dichloroethane(EDC) under the action of an initiator. Its main component is polyvinyl chloride. Meanwhile, adding some additives to enhance its heat resistance, toughness and ductility. Because of the characteristics of good chemical stability, corrosion resistance and water resistance, polyvinyl chloride is the most widely used raw material in plastic production.
Before using PVC Resin to make finished products, we should convert it into compounds first by adding additives. As we all know, commonly used additives are heat stabilizers, UV stabilizers, plasticizers, heat modifiers, flame retardants, bactericides, foaming agents, etc.

What is PVC K-value
In brief, the K value is an index indicating the polymerization degree and molecular weight of polyvinyl chloride. In addition, the viscosity number is also an indicator of the molecular weight of the polymer. Since this product is an amorphous linear polymer compound, it is with various different characteristics. The larger the relatively molecular weight, the higher the viscosity, the better the strength, stiffness, toughness, heat and low temperature resistance of the material, but the worse the molding processability. On the whole, the difference in K value of polyvinyl chloride resin will have a certain impact on the processing technology and product performance. Therefore, when purchasing polyvinyl chloride resin, customers need to choose the suitable grade depends on the K value and applications.
By comparison, K70-75 PVC resin with high K value and higher molecular weight has the best mechanical properties. But it is more difficult to process.
In general, PVC resin k65/k66, PVC resin k67/k68 with suitable K value have a good balance between mechanical properties and processability. So they are the most popular and can meet the needs of the most PVC applications.
Compared to other types of PVC resin, K58-60 polyvinyl chloride with low value has the lowest mechanical properties and the processing is easiest. However, it has many difficulties in the application process.
SG3 is for hoses, leathers, wire cables, shoes and other general purpose soft products.
SG5 is for pipes, profile, fittings, panels, injection, moulding, sandals, etc.
SG7/SG8 is for bottles, sheets, calendaring, rigid injection and moulding pipes.
