Main uses and industrial chain of PVC
1.PVC profiles and profiles are the largest areas of PVC consumption in China, accounting for about 25% of the total PVC consumption, which are mainly used to make doors and windows and energy-saving materials. At present, their applications are still increasing in a large number throughout the country. 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 Among many PVC products, PVC pipe is the second largest consumption field, accounting for about 20% of its consumption. In China, PVC pipes have developed earlier than PE pipes and PP pipes, with many varieties, excellent performance and wide application range, and occupy an important position in the market.
3. The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC and additives are mixed and plasticized, they are made into transparent or colored films with specified thickness by a three-roll or four-roll calender, and processed into calendered films by this method. You can also cut heat-sealed packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. Wide transparent film can be used in greenhouses, plastic greenhouses and plastic films. Biaxially stretched film can be used for shrink packaging because of its thermal shrinkage. 4. Add stabilizer, lubricant and filler into 4. PVC hard materials and plates. After mixing, hard pipes, special-shaped pipes and corrugated pipes with various diameters can be extruded by an extruder to be used as sewer pipes, drinking water pipes, wire sleeves or stair handrails. By overlapping and hot-pressing calendered sheets, hard plates of various thicknesses can be manufactured. The plate can be cut into the required shape, and then welded with hot air and PVC covered electrode into various chemical corrosion-resistant storage tanks, air ducts and containers.
5. Soft 5.PVC products can be extruded into hoses, cables and wires. Passing through an extruder; Plastic sandals, soles, slippers, toys, auto parts, etc. can be made by injection molding machine with various molds.
6.PVC packaging materials PVC products are mainly used to package various containers, films and hard sheets. PVC containers mainly produce PTP packaging of mineral water, beverages, cosmetic bottles and medicines, as well as packaging of refined oil. PVC film can be used for extrusion with other polymers to produce low-cost laminated products and transparent products with good barrier properties. PVC film can also be used for stretching or heat shrinking packaging, and used for packaging mattresses, fabrics, toys and industrial products.
7.PVC wallboard and floor PVC wallboard are mainly used to replace aluminum wallboard. PVC floor tiles not only contain part of PVC resin, but also contain recycled materials, adhesives, fillers and other components, which are mainly used for hard floors in airport terminals and other places.
8.PVC daily consumption luggage is a traditional product made of PVC. PVC is used to make all kinds of imitation leather, used in bags and sporting goods, such as basketball, football and rugby. It can also be used to make uniform belts and special protective equipment. PVC fabrics for clothing are generally water-absorbent fabrics (uncoated), such as ponchos, baby pants, imitation leather jackets and various rain boots. PVC is used in many sports and entertainment products, such as toys, records and sporting goods. At present, PVC toys have increased greatly, which has advantages because of its low production cost and easy molding.
