The appearance is white spherical particles with smooth surfaces, high and uniform internal porosity, high apparent density, good dry flow, and Easy to plasticize. It is an upgraded new variety of PVC special resin, suitable for making rigid pipes, especially large-diameter pipes.
PVC resin has a wide range of applications and can be used in the production and processing of PVC hard products, soft products, coatings and adhesives.
(1) PVC general soft products can be extruded into hoses, cables, wires, etc. using an extruder: using an injection molding machine with various molds, it can be made into plastic sandals, soles, slippers, toys, auto parts, etc. (2) PVC film After PVC is mixed with additives and plasticized, a three-roller or four-roller rolling machine is used to form a transparent or colored film with a specified thickness. The film is processed in this way to become a calendered film. It can also be processed by cutting and heat sealing to process packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. The wide transparent film can be used for greenhouse plastic greenhouses and mulch films. The biaxially stretched film has the characteristics of heat shrinkage and can be used for shrink packaging (3) PVC coated products Artificial leather with a backing is made by applying PVC paste on cloth or paper, and then plasticizing it at above 100 degrees Celsius . PVC and additives can also be calendered into a film, and then pressed with the substrate to form artificial leather. Artificial leather without a substrate is directly calendered into a soft sheet of a certain thickness by a calender, and then embossed with patterns. Artificial leather can be used to make suitcases, bags, book covers, sofas and car seat cushions, as well as floor leather, which can be used as floor coverings in buildings.
(4) PVC foam products When mixing soft PVC, add an appropriate amount of foaming agent to make a sheet, which is foamed and molded into foam plastic, which can be used as foam slippers, sandals, insoles, and shock-proof cushioning packaging materials. An extruder can also be used to make low-foaming hard PVC sheets and special profiles, which can be used as a substitute for wood and are a new type of building material.
(5) PVC transparent sheet PVC is added with impact modifier and organic tin stabilizer, and is mixed, plasticized, and calendered to become a transparent sheet. Thermoforming can be used to make thin-walled transparent containers or for vacuum blister packaging. It is an excellent packaging material and decorative material such as moon cake packaging boxes. (6) Stabilizers, lubricants and fillers are added to PVC hard board and plate PVC. After mixing, an extruder can be used to extrude hard pipes, special-shaped pipes and corrugated pipes of various diameters for use as sewer pipes and drinking water. Tubes, wire casings
