General Information

Frequently Asked Questions

Polyvinyl chloride, referred to as PVC in English, is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in peroxides, azo compounds and other initiators or under the action of light and heat according to the mechanism of free radical polymerization.

Uses of PVC resin:

Soft products: PVC resin can produce many types of soft products. Extruders can be used to make PVC resin into hoses, wires and cables, etc.; PVC resin can also be made into various exquisite mould toys through small syringes.

Film: Add additives to the PVC resin, and after plasticizing, it can be made into films of different thicknesses after being pressed by a pressing machine. The packed film can be made into plastic bags, raincoats, air toy holders, etc., after careful cutting. Because of its thermal expansion and cold contraction characteristics, the film made of PVC resin is very convenient for shrink packaging, and the plastic packaging bags on the surface are basically made of PVC resin.

Coated products: Many artificial leathers on the market are made of PVC resin, which is formed by plasticizing PVC resin at a temperature above 100 degrees. Synthetic leather can be used to make suitcases, leather blisters, book covers, etc. Because the quality of artificial leather is good and the price is reasonable, many building paving materials are made of synthetic leather.

Foam products: A foaming agent is added to the PVC resin to make a sheet. After foaming, PVC is shaped into plastic foam. The PVC resin treated in this way can also be used to make slippers, insoles and many shockproof and cushioning packaging materials. The rigid PVC board, after this treatment, can even replace wood and be used as a building material.

Transparent sheet: Add organic stabilizer to PVC resin; after a series of mixing and plasticizing, it can support the material of the head surface. It can be made into a thin-walled transparent container after thermoforming. Many vacuum packaging adopts this method. Because of its excellent packaging quality, it has always been trendy.
