What material is PVC

The full English name of PVC is polyvinylchloride (PVC molecular structure) abbreviation. Generally speaking, our common PVC is a kind of plastic decoration material. Its chemical name is polyvinyl chloride. It is composed of amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). It has mechanical properties, strong acid and salt resistance, and a low softening point. Stable chemical properties. Commonly used to make thin plates, wires, cable insulation, seals and other items.

PVC raw materials

The essence of PVC is a kind of vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, which is used in building materials, packaging, medicine and many other industries. Among them, the building materials industry accounts for the largest proportion at 60%, followed by the packaging industry, and there are several other small-scale applications.

What material is PVC?

What material is PVC? PVC is also called polyvinyl chloride. The density of pure PVC is 1.4g/cm³, and the density of polyvinyl chloride plastic parts added with plasticizers and fillers is generally 1.15-2.00g/cm³. Rigid PVC has good tensile, flexural, compressive and impact resistance, and can be used as a structural material alone. The flexibility, elongation at break, and cold resistance of soft PVC will increase, but the brittleness, hardness, and tensile strength will decrease. Polyvinyl chloride has good electrical insulation properties, can be used as low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCL gas, and make polyvinyl chloride discolor, so its application range is narrow, and the use temperature is generally between -15 and 55 degrees.

Types of PVC

According to different hardness, PVC is divided into hard PVC and soft PVC.

1. Soft PVC

Soft pvc

Soft PVC contains softeners that are easy to become brittle and difficult to store, so its use range is limited. Common soft PVC is generally used for floors, ceilings, and leather surfaces.

2. Rigid PVC

Also known as UPVC, or PVC-U products. Hard PVC does not contain softener, so it is flexible, easy to form, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. It has a wide range of applications: pipeline industry, water supply and drainage, flame-retardant electrical cable casing, electrical appliances, flame-retardant switch housings, sockets, profiles, plastic steel, partial fenders, bumpers, etc.

Application of PVC

Compared with Kimura and steel, PVC has the advantages of the high elasticity, high cold resistance, high abrasion resistance, and good finish. Therefore, the proportion of PVC applications in the world is rough: 65% for construction plastics, 8% for packaging, 7% for electrical and electronics, and furniture And decoration accounted for 5%, general consumption 4%, and other 11%.

Due to its high chemical stability, it can be used to make anti-corrosion pipelines, pipe fittings, oil pipelines, centrifugal pumps, and blowers, etc. Polyvinyl chloride hard boards are widely used in the chemical industry to make linings for various storage tanks, corrugated boards for buildings, door and window structures, wall decorations, and other construction materials. Due to its excellent electrical insulation performance, it can be used in the electrical and electronic industries to manufacture plugs, sockets, switches and cables. In daily life, PVC is used to make sandals, raincoats, toys and artificial leather, etc.

Polyvinyl chloride has higher mechanical strength and better corrosion resistance. It can be used to make waste gas discharge and detoxification towers and gas-liquid conveying pipes in chemical, textile and other industries, and can also replace other corrosion-resistant materials to make storage tanks, centrifugal pumps, ventilators and joints. When the plasticizer is added in an amount of 30% to 40%, soft polyvinyl chloride is produced, which has high elongation, soft products, good corrosion resistance and electrical insulation, and is often made into thin films. Industrial packaging, agricultural seedlings and daily raincoats, table cloths, etc., can also be used to make acid and alkali-resistant hoses, cable sheaths, insulation layers, etc.

PVC material has a wide range of uses, with good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics. It is mainly used for production: PVC cards, PVC OEM, pvc iron wire, PVC curtains, PVC coated welded wire mesh, PVC foam Boards, PVC ceilings, PVC water pipes, PVC skirting lines, etc., as well as threading pipes, cable insulation, plastic doors and windows, plastic bags, etc. PVC products can be seen everywhere in our daily lives. PVC is used to make all kinds of imitation leather, used in luggage, sports products, such as basketball, football and rugby. It can also be used to make belts for uniforms and special protective equipment.

What is PVC pipe?

PVC pipe

PVC pipe (UPVC pipe) rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It is the first plastic pipe to be developed and applied. UPVC pipe has strong corrosion resistance, easy to bond, low price of PVC pipe, and has hard texture. However, due to the seepage of UPVC monomer and additives, it is only suitable for water supply systems whose conveying temperature does not exceed 45°C.

What is PVC board

PVC board is a board with a honeycomb mesh structure made of PVC as raw material. According to the production process, it can be divided into PVC skinned foam board and PVC free foam board.

PVC foam board has the characteristics of anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, plannable, easy to thermoform, hot bending processing, etc., so it is widely used in furniture, cabinets, bath cabinets, exhibition shelves, Box core layer, indoor and outdoor decoration, building materials, chemical industry and other fields, advertising signs, printing, silkscreen, inkjet, computer lettering, electronic instrument product packaging, and other industries. PVC hard plastic board has excellent corrosion resistance, insulation, and certain mechanical strength; after secondary processing, it can be made into the sulfuric acid (hydrochloric acid) tank (barrel box); empty needle holder for medicine, chemical process holder; public Toilet water tank; various special-shaped products and containers such as templates, decorative panels, exhaust ducts, equipment linings, etc. of processed products. It is an ideal material for chemical, building materials, decoration and other industries.

PVC floor

PVC floor is a new type of light-body floor decoration material that is very popular in the world today, also known as "light-body floor material". It is a popular product in Japan, South Korea, Europe, America and Asia. It has been popular abroad. It entered the Chinese market in the early 1980s and has been widely recognized in large and medium-sized cities in China. It is widely used, such in indoor homes and hospitals. , Schools, office buildings, factories, public places, supermarkets, commerce, sports venues and other places. "PVC floor" refers to the floor made of polyvinyl chloride materials. Specifically, it takes polyvinyl chloride and its copolymer resin as the main raw material, adds fillers, plasticizers, stabilizers, colorants, and other auxiliary materials, and then applies coating processes or calendering, extrusion, or extrusion on a continuous sheet-like substrate. Craftsmanship.
