There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.

The dental caries are dominated by imported technology, independent innovation, taking measures in materials, processes and testing, and actively broadening the product spectrum to enable the company's products to be serialized and multi-category, and to meet the requirements of the market at multiple levels and individualization.
During the 11th Five-Year Plan period, cavities continued to develop new products. In five years, more than 10 new products were developed each year and 6 patents were successfully declared. By 2010, the company's transmission products have formed vertical and horizontal levels and become horizontal series, forming series on the spectrum, and a gradient on the price. Form QJ6S series box series and QJ8S series, QJ9S series, QJ10S series, QJ12S series and QJ16S series products, to meet the assembly requirements of large and medium-sized passenger cars, heavy-duty trucks, all kinds of special vehicles and special vehicles.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
