k67 pvc resin
k67 pvc resin,
PVC K 67 is one of the grades of polyvinyl chloride that is used in pipes.
PVC K67 is designed to give an easy processing product for extrusion rigid
applications since it has moderate melt viscosity with high melt strength. It is mainly
designed for pipe and profile products.
-Rigid pipes (Pressure and non-pressure)
-Corrugated tubes and conduits
-Rigid profiles
PVC resin is a type of thermoplastic resin that is used in the manufacture of products made of plastic due to its high flexibility.
pvc resin for pipe,
PVC S-1000 polyvinyl chloride resin is produced by suspension polymerization process using vinyl chloride monomer as raw material. It is a kind of polymer compound with a relative density of 1.35 ~ 1.40. Its melting point is about 70 ~ 85℃. Poor thermal stability and light resistance, over 100℃ or long time under the sun hydrogen chloride begins to decompose, plastic manufacturing needs to add stabilizers. The product should be stored in a dry and ventilated warehouse. According to the amount of plasticizer, the plastic softness can be adjusted, and the paste resin can be obtained by emulsion polymerization.
Grade S-1000 can be used to produce soft film, sheet, synthetic leather, piping, shaped bar, bellow, cable protection piping, packing film, sole and other soft sundry goods.
