PVC K value 57,
PVC resin used to manufacture foam board,
The PVC resin with a K value of 55-68 can be used to manufacture hard foam, that is, hard PVC low-foam products, which is different from the K value provided in the past information and books. PVC resins with K values of 69-77 have been shown to be suitable for the manufacture of soft foams. There are many ways to produce PVC resin, suspension method, emulsion method and bulk polymerization of PVC resin are available raw materials for foamed products, usually suspension and bulk polymerization of PVC resin is appropriate. PVC copolymers and grafted polymers (granular polymers) also have good processability and are rarely used because of price factors.

Polyvinyl Chloride, referred to as PVC, is one of the industrialized plastic varieties, the current output is second only to polyethylene. Polyvinyl chloride has been widely used in industry, agriculture and daily life. Polyvinyl chloride is a polymer compound polymerized by vinyl chloride. It’s thermoplastic. White or light yellow powder.It is soluble in ketones, esters, tetrahydrofurans and chlorinated hydrocarbons. Excellent chemical resistance. Poor thermal stability and light resistance, more than 100℃ or long time exposure to sunlight began to decompose hydrogen chloride, plastic manufacturing needs to add stabilizer. Electric insulation is good, will not burn.

Grade S-700 is mainly used to produce transparent sheets, and can be rolled into  rigid and semi-rigid sheets for package, floor material, hard film for lining (for candy wrapping paper or cigarette packing film), etc. It can also be extruded to hard or semi-hard film, sheet, or irregularly shaped bar for package. Or it can be injected to make joints, valves, electric parts, auto accessories and vessels.
