The main purpose of PVC plastic particlesThe main purpose of PVC plastic particles
1. PVC general soft products.
Using the extruder, it can be extruded into hoses, cables, wires, etc.; using injection molding machines and various molds, it can be made into plastic sandals, soles, slippers, toys, auto parts, etc.
2. PVC transparent material.
After mixing and plasticizing PVC with additives, a three-roll or four-roll calender is used to make a transparent or colored film with a specified thickness, and the film is processed by this method to become a rolled 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 greenhouse, plastic greenhouse and mulch film. The biaxially stretched film can be used for shrink packaging due to the heat shrinkage characteristics.
3. PVC coated products.
Artificial leather with a substrate is made by applying PVC paste on cloth or paper, and then plasticizing it at a temperature above 100 degrees Celsius. It can also be formed by rolling PVC and additives into a film, and then pressing it with the substrate. The artificial leather without backing is directly calendered into a soft sheet with a certain thickness by a calender, and then pressed with a pattern. Artificial leather can be used to make suitcases, purses, book covers, sofas and car cushions, etc., as well as floor leather, used as a floor material for buildings.
4. PVC foam products.
When mixing soft PVC, add a proper amount of foaming agent to make a sheet, which is foamed into foam plastic, which can be used as foam slippers, sandals, insoles, and shock-absorbing cushioning packaging materials. It can also be made into low-foam rigid PVC sheet and profiled material based on extruder, which can replace wood for trial and is a new type of construction material.
5. PVC transparent sheet.
Add impact modifier and organotin stabilizer to PVC, and then mix, plasticize and calender to become transparent sheet. Using thermoforming, it can be made into thin-walled transparent containers or used in vacuum blister packaging. It is an excellent packaging material and decorative material.
6. PVC hard board and plate.
Stabilizers, lubricants and fillers are added to PVC. After mixing, extruders can be used to extrude hard pipes, special-shaped pipes and corrugated pipes of various calibers. They can be used as sewer pipes, drinking pipes, electric wire bushings or stair handrails. . The rolled sheets are overlapped and hot pressed to make hard plates of various thicknesses. The sheet can be cut into the desired shape, and then welded with hot air into various chemically resistant storage tanks, air ducts and containers using PVC welding rods.
The doors and windows are assembled with hard special materials. In some countries, they have occupied the market of doors and windows together with wooden doors and windows, aluminum windows, etc.; imitation wood materials, steel building materials; hollow containers.
