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.
APPLICATION
PVC general soft products. For the production of hoses, cables, wires, etc. With various molds, we can use them to make plastic sandals, shoe soles, slippers, toys, auto parts, etc.
PVC films. After mixing the polyvinyl chloride resin with some special additives and plasticized, it can be used to make a transparent or colored film with a specified thickness. Factory also use pvc films to process packaging bags, raincoats, tablecloths, curtains, inflated toys, etc. The wide transparent film is suitable to make greenhouses, mulching films. The biaxially stretched film has the characteristics of heat shrinkage and can make shrink packaging.
PVC coated products, such as artificial leather. Artificial leather with a backing is made by coating PVC paste resin on cloth or paper, and then plasticizing it at a temperature above 100ºC. For artificial leather without a substrate, the PVC emulsion resin is directly rolled into a soft sheet with a certain thickness by a calender. And then press the pattern.
PVC Foam products. When mixing flexible PVC, add an appropriate amount of foaming agent to make a sheet, and then foamed into foam plastic. In adition, it can be used to make foam slippers, sandals, insoles, shock-proof cushioning packaging materials, etc. And it is also the raw material to make low-foam hard PVC boards and profiles. With good performance, it can replace wood as a new type of construction material.
PVC transparent sheet. Add impact modifier and organic stabilizer to polyvinyl chloride resin, and then mix, plasticize and calender them to make transparent sheet. The PVC transparent sheet can be made into thin-walled transparent containers or used for vacuum blister packaging. It is an excellent packaging material and decorative material.
