What kind of material is PVC coated fabric?
PVC is polyvinyl chloride material, which is poisonous. Polyvinyl chloride, English abbreviation PVC (Polyvinylchloride), is a vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxides, azo compounds, and other initiators; or under the action of light and heat according to the mechanism of free radical polymerization. of polymers. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.
The main purpose:
1. PVC profiles
Profiles and profiles are the largest areas of PVC consumption in my country, accounting for about 25% of the total PVC consumption. They are mainly used to make doors and windows and energy-saving materials, and their application volume is still increasing significantly nationwide. In developed countries, the market share of plastic doors and windows also ranks first, such as 50% in Germany, 56% in France, and 45% in the United States.
2. PVC pipe
Among the many PVC products, PVC pipes are the second largest consumption field, accounting for about 20% of its consumption. In my country, PVC pipes are developed earlier than PE pipes and PP pipes, with many varieties, excellent performance, and wide application range, occupying an important position in the market.
3. PVC film
The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC and additives are mixed and plasticized, a transparent or colored film of specified thickness is made by using a three-roller or four-roller calendar, and the film is processed by this method to become a calendered film.
Packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. can also be processed by cutting and heat sealing. The wide transparent film can be used for greenhouse, plastic greenhouse, and plastic film. The biaxially stretched film can be used for shrink packaging because of its thermal shrinkage characteristics.
4. PVC hard material and board
Add stabilizers, lubricants, and fillers to PVC, and after mixing, use an extruder to extrude hard pipes, special-shaped pipes, and corrugated pipes of various diameters, which can be used as sewer pipes, drinking water pipes, wire casings or stair handrails.
The calendered sheets are superimposed and hot-pressed to make hard plates of various thicknesses. The plates can be cut into desired shapes, and then welded with hot air using PVC welding rods to form various chemical-resistant storage tanks, air ducts, and containers.
5. PVC general soft products
Extruders can be used to extrude hoses, cables, wires, etc.; injection molding machines can be used to match various molds to make plastic sandals, soles, slippers, toys, auto parts, etc.
6. PVC packaging material
PVC products are mainly used in various containers, films, and hard sheets for packaging. PVC containers are mainly used in the production of mineral water, beverages, and cosmetic bottles, and are also used in the packaging of refined oils.
PVC film can be used for coextrusion with other polymers to produce low-cost laminates, as well as transparent products with good barrier properties. PVC film is also used in stretch or shrink wrap for mattresses, cloth, toys, and industrial goods.
7. PVC siding and flooring
PVC siding is mainly used to replace aluminum siding. Except for a part of polyvinyl chloride resin, the other components of polyvinyl chloride floor tiles are recycled materials, adhesives, fillers, and other components, which are mainly used on the ground of airport terminal buildings and hard ground in other places.
8. Polyvinyl chloride consumer goods
A luggage bag is a traditional product made of polyvinyl chloride. Polyvinyl chloride is used to make various imitation types of leather for luggage bags and sports products such as basketball, football, and rugby. It can also be used to make belts for uniforms and special protective equipment.
Polyvinyl chloride fabrics for clothing are generally absorbent fabrics (no coating required), such as rain capes, baby pants, imitation leather jackets, and various rain boots. PVC is used in many sports and entertainment products, such as toys, records, and sports products. PVC toys and sports products have a large growth rate, and they have advantages due to their low production cost and easy molding.
9. PVC coated products
The artificial leather with backing is made by applying PVC paste on cloth or paper, and then plasticizing it above ℃. It can also be made by rolling PVC and additives into a film first and then pressing it with the substrate.
The artificial leather without backing is directly calendered into a soft sheet of a certain thickness by a calendar and then pressed with a pattern. Artificial leather can be used to make suitcases, purses, book covers, sofas, and car cushions, as well as floor leather, which is used as flooring materials for buildings.
10. PVC foam products
When soft PVC is kneaded, an appropriate amount of foaming agent is added to form a sheet, which is foamed and formed into foam plastic, which can be used as foam slippers, sandals, insoles, and shockproof cushioning packaging materials. It can also be used to form low-foaming hard PVC sheets and profiled materials based on extruders, which can be used instead of wood. It is a new type of building material.
11. PVC transparent sheet
Add impact modifier and organotin stabilizer to PVC, and become a transparent sheet after mixing, plasticizing and calendaring. It can be made into thin-walled transparent containers or used in vacuum blister packaging by thermoforming. It is an excellent packaging material and decorative material.
