Polyvinyl chloride, referred to as PVC, is a thermoplastic resin polymerized by vinyl chloride monomer under the action of an initiator. It is a homopolymer of vinyl chloride. The appearance is white powder, non-toxic and odorless. As one of the important organic synthetic materials, PVC resin has good physical and chemical properties, such as heat resistance, cold resistance, corrosion resistance, insulation, and flame retardancy. Therefore, polyvinyl chloride resin can be widely used in construction, electronics, automobiles, medical care, packaging and other fields.

According to different application ranges, polyvinyl chloride resin can be divided into: general-purpose PVC resin, high-polymerization PVC resin, and cross-linked PVC resin. The general-purpose PVC resin is formed by polymerization of vinyl chloride monomer under the action of initiator; high-polymerization PVC resin refers to the resin polymerized by adding chain extender to the polymerization system of vinyl chloride monomer; cross-linked PVC resin is the resin polymerized by adding cross-linking agent containing diene and polyene to the polymerization system of vinyl chloride monomer.

Main applicationsPVC SG3 is suitable for leathers, hoses, wire cables, shoes and other general purpose soft products.PVC SG5 can be mainly used for pipes, profiles, fittings, panels, injection, moulding, sandals, hard tube and decorative materials,etc.
Both PVC SG7 and PVC SG8 are suitable for sheets, bottles, calendaring, rigid injection molding and molded pipes.

As an important plastic material, PVC resin is widely used in modern industry and life. This resin can be processed into various plastic products, which can be divided into soft and hard products according to their uses. They are mainly used for the production of transparent sheets, pipe fittings, gold cards, blood transfusion equipment, soft and hard pipes, plates, doors and windows, Profiles, films, electrical insulation materials, cable sheaths, blood transfusion materials, etc. The following are the specific applications of PVC resin:

Construction field

  • Pipes and tubes. PVC resin is often used in construction to make pipes and tubes, such as drainage pipes. This is due to its excellent aging resistance, high impact strength and toughness, and relatively low price. PVC pipes account for about 20% of the total consumption of PVC in the construction field.
  • Door and window frames. PVC profiles are the largest area of ​​PVC consumption in my country, accounting for about 25% of the total PVC consumption, and are mainly used to make doors and windows and energy-saving materials.
  • Floor materials, wall coverings, roofing materials, etc. PVC resin is also used to make floor materials, wall coverings and roofing materials.

Packaging field

Food, cosmetics, and pharmaceutical packaging.  This resin is widely used in the packaging field, such as food packaging films, bottle cap seals, cosmetic packaging boxes, etc. It has good transparency, corrosion resistance, and weather resistance, which can effectively protect products and extend shelf life.

Electronic and electrical fields

  • Wire and cable insulation.  PVC resin has excellent electrical insulation and is widely used in the insulation layer of wires and cables.
  • Electrical component housing. PVC resin is also used as the housing of electrical components to provide protection and insulation.
  • Electronic connectors and plugs. Connectors and plugs made of PVC resin have good durability and stability.

Daily necessities

  • By using an extruder, PVC resin can be extruded into hoses, cables, wires, etc.
  • Using an injection molding machine with various molds, it can be made into plastic sandals, soles, slippers, toys, auto parts, etc.

Other industrial applications

  • Film manufacturing. After PVC is mixed with additives and plasticized, it can be made into transparent or colored films of specified thickness, which are used in greenhouses, plastic greenhouses, packaging and other fields.
  • Sheets and hard materials. After adding stabilizers, lubricants and fillers to PVC, it can be made into hard sheets and special-shaped tubes of various thicknesses, which are used to make various chemical-resistant storage tanks, air ducts and containers.

Medical field. PVC resin is also used in the medical field, such as blood transfusion equipment.

  • Strength and rigidity. PVC resin has good strength and rigidity and can withstand greater mechanical pressure and impact.
  • Wear resistance. This resin resin has high wear resistance, which makes it have a long service life in some applications.
  • Processability. It is easy to process and can be prepared into products of various shapes and sizes through processes such as extrusion, injection molding, and calendering.
  • Additive mixing. Polyvinyl chloride resin can be mixed with various additives (such as plasticizers, stabilizers, fillers, etc.) during processing to improve its performance and processability.
  • Weather resistance. It has good weather resistance in outdoor environments and can resist erosion by ultraviolet rays, acid rain and some chemicals.
  • Corrosion resistance. The product is resistant to erosion by most oils, alcohols and aliphatics, but not resistant to organic solvents such as aromatic hydrocarbons, chlorinated hydrocarbons, esters, etc.
  • Electrical properties. PVC resin is an excellent electrical insulating material with low electrical conductivity and high insulation strength, which makes it widely used in the electrical industry.
  • Environmental performance. In recent years, with the improvement of PVC synthesis technology, the content of vinyl chloride monomer in PVC resin has been successfully reduced to below 5×10^-6, and food-grade PVC resin can be obtained, showing good environmental performance.
  • Safety. The polyvinyl chloride resin itself is non-toxic, but the industrial additives used in its processing, especially heat stabilizers, may have varying degrees of toxicity. Therefore, when using PVC products, attention should be paid to its hygiene.

In summary, PVC resin is widely used in industry, construction, agriculture, daily life, packaging, electricity and other fields due to its excellent physical and chemical properties, good mechanical properties, easy processing, weather resistance and corrosion resistance, excellent electrical properties and high environmental performance.
