PVC is made of plastic and is not wear-resistant. PVC is a vinyl polymer and an amorphous synthetic material; In the practical application of PVC, a large number of stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and additives are added. Non flammable, high strength, climate change resistance and excellent geometric stability; It has strong resistance to oxidants, reducing agents and strong acids.

1、 What are the classifications of PVC?

1. Soft PVC

Soft PVC contains softener, which is easy to become brittle and difficult to preserve, so its application range is limited. Common soft PVC is generally used in floor, ceiling and leather surface.

2. Rigid PVC

Hard PVC does not contain softener, so it has good flexibility, easy to form, not easy to crisp, non-toxic, pollution-free and long storage time. Therefore, it has great development and application value. It has a wide range of applications: pipeline industry, water supply and drainage, flame-retardant wire and cable sleeve, flame-retardant switch shell, socket, profile, plastic steel, some fender, bumper, etc.

2、 What is PVC board?

1. PVC board is a board with honeycomb mesh structure in cross section 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.

2. PVC foam board has the characteristics of anti-corrosion, moisture-proof, mildew proof, non water absorption, drillable, sawable, planed, easy thermoforming and thermal bending processing. Therefore, it is widely used in furniture, cabinet, bath cabinet, exhibition rack board, box core layer, indoor and outdoor decoration, building materials, chemical industry and other fields, advertising signs, printing, silk screen printing, spray painting, computer lettering Electronic instrument product packaging and other industries.

3. PVC rigid plastic board has excellent corrosion resistance, insulation and certain mechanical strength; After secondary processing, it can be made into sulfuric acid (hydrochloric acid) tank (barrel box); Empty needle frame and chemical process frame for medicine; Public toilet water tank; Various special-shaped products and containers such as formwork, decorative board, exhaust pipe and equipment lining of processing products. It is an ideal material for chemical industry, building materials, decoration and other industries.

3、 Is PVC board environmentally friendly?

1. Whether PVC sheet is environmentally friendly or not should first start with the manufacturer’s social responsibility and production process. Now the whole society advocates environmental protection and green, and it is difficult for polluting materials to have a market. Therefore, PVC sheet enterprises with environmental awareness begin to formulate “cradle to cradle” solutions, that is, how to design, purchase, and manufacture with less energy and higher efficiency Manufacture and delivery of products; In the later PVC sheet product life cycle, how to convert these products into different products or new products.

2. At present, the performance of the whole PVC plate industry is still good, and the production standards of most enterprises have already reached E1 or even E0. There are also grades of PVC plates, and the quality grades are Grade A, grade B and grade C. The specific gravity of grade a PVC plate is 1.5, which is brand new; The specific gravity of grade B PVC plate is 1.6, and an appropriate amount of filler is added to the new material; The specific gravity of grade C PVC plate is 1.6, which is an excellent recycled material.

4、 What are the characteristics and classification of PVC sheet?

1. Antistatic PVC board (antistatic PVC board). The flame retardant grade is UL-94: V-0; Color: transparent, smoke, milky white, gray, etc; Application: equipment cover, dust-free box, test fixture, etc.

2. PVC hard board. The color is generally gray and white. PVC color hard board can also be produced according to customers’ needs. Its color is bright and beautiful. Upper limit of product thickness: less than 25mm; Product width: 900mm, 1300mm, 1500mm; It has excellent chemical stability, corrosion resistance, high hardness, no water absorption, no deformation, easy processing and so on.

3. PVC transparent board. Upper limit of product thickness: less than 20mm; Product upper limit width: 1300mm; The product is a kind of high-strength and transparent plastic plate produced by imported raw and auxiliary materials. Product colors include white, sapphire blue, Tan, coffee and other varieties.

4. PVC flexible board. The surface is glossy and soft. There are brown, green, white, gray and other colors to choose from. The product is made of materials, fine production and wide application. Performance characteristics: soft, cold resistant, wear-resistant, acid, alkali resistant, corrosion resistant, tear resistant, excellent weldability, and physical properties are superior to other coiled materials such as rubber.
