Polyvinyl chloride plastics have different forms, great differences, and a variety of processing methods, which can be pressed, extruded, injected, coated, etc. PVC plastic is often used in the manufacture of film, artificial leather, wire and cable insulation, hard products, flooring, furniture, sports equipment and so on

PVC polyvinyl chloride products can generally be divided into hard and soft two categories. Hard products are processed without plasticizer, while soft products are processed with a large amount of plasticizer. PVC polyvinyl chloride is originally a hard plastic, its glass transition temperature is 80 ~ 85℃. After adding plasticizer, the glass transition temperature can be reduced, which is convenient for processing at a lower temperature, so that the flexibility and plasticity of the molecular chain can be increased, and can be made into flexible soft products at room temperature. The amount of plasticizer added to general soft PVC plastic is 30% ~ 70% of PVC.

PVC polyvinyl chloride in processing added plasticizer, stabilizer, lubricant, colorant, filler, can be processed into a variety of profiles and products. The specific uses of PVC are as follows:

1, PVC profile,

The SECTION, THE SPECIAL SECTION IS THE BIGGEST FIELD ON PVC CONSUMPTION IN OUR COUNTRY, ACCOUNTS FOR ABOUT 25% OF TOTAL CONSUMPTION ON PVC, MAINLY USED TO MAKE DOORS AND Windows AND ENERGY-SAVING MATERIAL, AT PRESENT ITS dosage SHOULD BE USED IN THE WHOLE NATION STILL HAS LARGER GROWTH.

2. PVC pipe

PVC pipe is the second largest consumer area of PVC, accounting for about 20% of its consumption. In our country, PVC pipe has been developed earlier than polyethylene (PE) pipe and polypropylene (PP) pipe, there are many varieties, excellent performance, a wide range of use and important position in the market.

3. PVC film

PVC film is the third largest consumer area of PVC, accounting for about 10% of its consumption. Using the calender can be PVC made into a specified thickness of transparent or colored film, the film produced by this method is called calender film. The granular raw material of PVC can also be blown into film by blow molding machine, and the film produced by this method is called blow plastic film. Thin film is of great use. It can be processed into packaging bags, raincoats, tablecloths, curtains, inflatable toys and so on by cutting and thermal bonding. The wide transparent film can be used to build greenhouses and plastic greenhouses, or as mulch.

4, PVC board and sheet

PVC add stabilizer, lubricant and filler, after mixing, extruder can extrude a variety of caliber of hard pipe, shaped pipe, bellows, used as down pipe, water pipe, wire sleeve or stair handrail. Hard sheets of various thickness can be made by hot pressing the laminated sheets. The sheet can be cut into the desired shape, and then PVC welding rod is used to weld into a variety of chemical corrosion resistant storage tanks, air ducts and containers with hot air.

5, PVC general soft products

The use of extruder can be squeezed into hoses, cables, wires, etc. Using injection molding machine with various molds, plastic sandals, soles, slippers, toys, car accessories, etc.

6. PVC packaging materials

PVC products are mainly used for packaging in various containers, films and hard pieces. PVC containers mainly produce mineral water, drinks, cosmetics bottles, also used for refined oil packaging.

7. PVC siding and flooring

PVC siding is mainly used to replace aluminum siding. In addition to a part of PVC resin, the remaining components of PVC floor tile are recycled materials, adhesives, fillers and other components, mainly used in the airport terminal floor and other places of hard ground.

8, PVC consumer goods

PVC products can be found everywhere in our daily life. PVC is used to make a variety of imitation leather for luggage, sports products such as basketball, football and rugby. Belts can also be used to make uniforms and special protective equipment. PVC fabrics for clothing are generally absorbent fabrics (without coating), such as ponchos, baby pants, imitation leather jackets and various rain boots. PVC is also used in many sports and entertainment products, such as toys, records and sporting goods.
