For PVC resin, a variety of processing methods can be carried out using an extruder:

General soft products can be extruded into cables, wires, and hoses using a PVC extruder; meanwhile, injection molding machines equipped with various molds can produce shoe soles, slippers, a wide range of plastic sandals, as well as toys and automotive components.

PVC film is produced by blending PVC with additives, plasticizing the mixture, and then passing it through a three- or four-roll calender to form transparent or colored films of specified thickness. This process can be used to manufacture calendered films, which can further be cut and heat-sealed to produce raincoats, tablecloths, curtains, packaging bags, and more.

Inflatable toys, among other products. Wide‑width transparent films can be used for greenhouses, plastic tunnels, and mulch films; biaxially oriented films, owing to their heat‑shrinkable properties, are suitable for shrink packaging.

PVC foam products: During the compounding process, an appropriate amount of blowing agent is added to soft PVC to produce sheets, which are then subjected to foaming and molding to yield foam plastics. These materials can be used for sandals, shoe insoles, foam slippers, and shock‑absorbing packaging, among other applications. Additionally, low‑density foamed PVC can be extruded using a PVC extruder.

Rigid PVC sheets and profiles. It is a new type of building material that can be used as a substitute for wood.

PVC-coated products, including synthetic leather with a backing, are produced by first coating a prepared PVC paste onto fabric or paper and then plastifying it at temperatures above 100°C; alternatively, PVC can be calendered with additives into a thin film and subsequently laminated to the backing. In contrast, synthetic leather without a backing…

It is directly calendered into a soft, thin sheet of a specified thickness, after which a pattern can be embossed onto its surface. Artificial leather has a wide range of applications: it can be used to make handbags, book covers, book jackets, sofas, and car seat cushions, and it can also be manufactured into floor covering for architectural purposes.

Flooring materials.

PVC paste resin is produced by dispersing PVC emulsion or microsuspension resin in a liquid plasticizer, allowing it to swell and plasticize into a plasticized sol. Stabilizers, fillers, colorants, and other additives are then incorporated, followed by thorough mixing and degassing to formulate the PVC paste. This paste is subsequently applied via casting, impregnation, or dip‑coating.

It is further processed into a variety of products, such as coat hangers, tool handles, Christmas trees, and more.

PVC transparent sheet is produced by adding impact modifiers and organotin stabilizers to PVC, followed by blending, plasticization, and calendering to obtain a clear sheet. It can then be thermoformed into thin-walled, transparent containers and is also suitable for vacuum thermoforming packaging, such as mooncake boxes. It is an excellent…

High-quality packaging and decorative materials.

PVC rigid sheets and boards are produced by adding stabilizers, lubricants, and fillers to PVC, followed by compounding. Using an extruder, these materials can be processed into various types of rigid pipes, profiled pipes, corrugated pipes, and other products, which are used for drainage pipes, potable water pipes, electrical conduit, or stair handrails, among other applications; after calendering…

By laminating thin sheets and subjecting them to hot pressing, rigid panels of various thicknesses can be produced. These panels can be cut into a wide range of desired shapes and, using PVC welding rods and hot air, welded into chemically resistant storage tanks, ductwork, vessels, and other components.

Other applications of PVC: Using a PVC extruder, PVC can be processed into rigid profiled materials for use in window and door assembly. In some countries, windows and doors assembled from rigid PVC profiles now share the market with wooden and aluminum windows and doors.
