What Are The Main Uses Of Polyvinyl Chloride Resin

PVC resin

Due to its high chemical stability, it can be used to make anti-corrosion pipelines, pipe fittings, oil pipelines, centrifugal pumps and blowers. The rigid board of PVC is widely used in the chemical industry to make the lining of various storage tanks, corrugated boards of buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used in the manufacture of plugs, sockets, switches and cables in the electrical and electronic industries. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather, etc.!

Specific classification:

(1) PVC general soft products

Extruders can be used to extrude hoses, cables, wires, etc.; injection molding machines can be used with various molds to make plastic sandals, soles, slippers, toys, auto parts, etc.

(2) PVC film

After PVC and additives are mixed and plasticized, a three-roll or four-roll calender is used to form a transparent or colored film with a specified thickness, and the film is processed by this method to become a calendered film. It can also be cut and heat-sealed to process packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. The wide transparent film can be used for greenhouses, plastic greenhouses and plastic films. The biaxially stretched film has the characteristics of thermal shrinkage and can be used for shrink packaging.

(3) PVC coated products

The artificial leather with backing is made by coating PVC paste on cloth or paper, and then plasticizing it at above 100 degrees Celsius. It can also be made by calendering PVC and additives into a film first, and then pressing it with the substrate. The artificial leather without substrate is directly calendered into a soft sheet of a certain thickness by a calender, and then embossed with patterns. Artificial leather can be used to make luggage, leather bags, book covers, sofas and car seat cushions, etc., as well as floor leather, used as floor coverings for buildings.

(4) PVC foam products

When soft PVC is mixed, an appropriate amount of foaming agent is added to make a sheet, which is foamed and molded into foam plastic, which can be used as foam slippers, sandals, insoles, and shock-proof cushioning packaging materials. It can also be used to form low-foaming rigid PVC sheets and profiles based on extruders, which can replace wood for trial use and are a new type of building material.

(5) PVC transparent sheet

Add impact modifier and organic tin stabilizer to PVC, and it becomes a transparent sheet after mixing, plasticizing and calendering. It can be made into thin-walled transparent containers or used for vacuum blister packaging by thermoforming. It is an excellent packaging material and decorative material - such as moon cake packaging boxes.

(6) PVC paste resin

Disperse PVC in a liquid plasticizer to swell and plasticize to form a plastisol, usually using emulsion or micro-suspended resin, plus stabilizers, fillers, colorants, etc. It is made into PVC paste, and then processed into various products by feeding, dipping, casting or slush molding. Such as hangers, tool handles, Christmas trees, etc.

(7) PVC rigid board and board

Stabilizers, lubricants and fillers are added to PVC. After mixing, hard pipes, special-shaped pipes and corrugated pipes of various diameters can be extruded with an extruder, which can be used as sewer pipes, drinking water pipes, wire casings or stair handrails. . The rolled sheets are overlapped and hot pressed to make hard plates of various thicknesses. The plate can be cut into the desired shape, and then welded into various chemical-resistant storage tanks, air ducts and containers using PVC welding rods with hot air.

(8) PVC other

Doors and windows are assembled with hard special-shaped materials. In some countries, it has occupied the market of doors and windows together with wooden doors, windows and aluminum windows; imitation wood materials, substitute steel building materials (north, seaside); hollow containers.
