Main USES of PVC materials

1. Polyvinyl chloride profiles

Profiles, profiles is one of the largest area, PVC consumption in China accounted for about 25% of the total PVC consumption, mainly used in the production of doors and Windows and energy-saving materials, its are across the country still has a substantial increase. In developed countries, the market share of plastic doors and Windows is also the highest, such as 50% in Germany, 56% in France and 45% in the United States.

2. PVC pipe material

Among many PVC products, PVC pipe is its second largest consumer area, accounting for about 20% of its consumption. In China, PVC pipe was developed earlier than PE pipe and PP pipe, with many varieties, excellent performance, wide application range and important position in the market.

3. Polyvinyl chloride film

The consumption of PVC in the field of PVC film ranks the third, accounting for about 10%. After PVC is mixed with additives and plasticized, transparent or colored films of specified thickness can be formed by three or four rollers of calender mechanism. You can also cut, heat up and process packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. Wide transparent film can be used for greenhouses, plastic greenhouses and geomembranes. The properties of a bidirectional stretched thin film subjected to heat contraction may be used in shrink packing.

4.PVC hard materials and plates

Added to PVC stabilizer, lubricant, and packing, after mixing with extruder can squeeze out a variety of caliber pipe, special pipe, corrugated pipe, used for the pipe, drinking water pipe, wire casing or stair armrest. The rolled sheet can be made into hard sheet of various thickness by overlapping hot pressing. The plate can be cut into the desired shape, and then welded with hot air by PVC electrode into tanks, air ducts and containers that are resistant to chemical corrosion.

5. General soft PVC products

Extruder can be extruded into hoses, cables, wires, etc. Plastic sandals, soles, slippers, toys and car accessories can be made by injection molding machine.

6. PVC packaging materials

PVC products are mainly used for packaging containers, films and hard films. PVC container mainly produces mineral water, beverages, cosmetics bottles, and also used for refined oil packaging. PVC film can be used to extrude low cost laminated products together with other polymers, as well as transparent products with good barrier properties. PVC film can also be used for stretching or heat-shrinkable packaging for mattresses, cloth pieces, toys and industrial goods.

7. PVC wallboard and floor

PVC cladding is mainly used to replace aluminum cladding. In PVC floor tile in addition to the part of the PVC resin, the rest of the components is recycled material, adhesive, filler and other components, mainly used in airport terminal area and other places of hard ground.

8. PVC consumer goods for daily use

Luggage bags are traditional products made from PVC, which is used to make all kinds of imitation leather, used for luggage bags, sports products, such as basketball, football and football. It can also be used to make belts for uniforms and special protective equipment. Polyvinyl chloride fabrics for clothing are generally absorbent (no need to be coated) such as raincoats, baby pants, leather jackets and boots. Polyvinyl chloride (PVC) is used in many sports entertainment, such as toys, music and sports supplies, PVC toys and sporting goods increase, because of its low production cost, easy to shape and the advantage.

9.PVC coated products

A substrate of artificial leather is to apply PVC confused on the cloth or paper, and then in plasticizing and above 100 ℃. PVC and auxiliary can also be first compressed into a film, and then combined with the substrate. The unlined artificial leather is directly rolled by the calender into a certain thickness of soft thin sheet, and then embossed with pattern. Artificial leather can be used to make leather cases, bags, book covers, sofas and car cushions, as well as floor leather for building paving materials.

10.PVC foam products

When mixed with soft PVC, add the right amount of foaming agent to make sheet material. After foaming, it is formed into foam plastic, which can be used as foam slippers, sandals, insole and shock-proof buffer packaging material. It can also be used as a new type of building material, which can replace wood.

11.PVC transparent sheet material

PVC added impact modifier and organotin stabilizer, through mixing, plasticizing, compression and become transparent sheet material. It can be made into thin-walled transparent container or used in vacuum blister packaging by hot forming. It is an excellent packaging material and decorative material.

12. Other

Doors and Windows are made of hard and heterogeneous materials. In some countries with wooden doors, Windows, aluminum Windows and other joint ownership of the Windows and doors market; Imitation wood materials and substitute steel materials (north, seaside); Hollow container.

Virtual circuit is one of the packet switching network services (the other is a datagram service), in a nutshell, is the internal control mechanism, through the network to build a virtual logical connection between the user host, and the validity of the guarantee in the upload messenger bag and sequentiality, before and after the communication for the establishment of virtual circuit and removal. Permanent virtual circuit is a virtual circuit established when the network is initialized, and the virtual circuit is maintained. Both x.25 network and b-isdn provide PVC services. PVC plastic bags are generally prohibited.
