Brief introduction of pvc board

PVC board polyvinyl chloride (PVC) plastic is a polymer formed by free radical polymerization of vinyl chloride monomer. The English name is polyviny chloride, or PVC for short.

PVC can be divided into soft PVC and hard PVC. During this period, hard PVC accounted for about 2/3 of the market, and soft PVC accounted for 1/3. 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 dotted film, attached film, used in building materials, packaging, medicine and many other occupations. Among them, the occupation of building materials accounts for the largest proportion, at 60%, followed by the occupation of packaging, and there are several other occupations that are used in a small range.

Soft PVC is usually used for floors, ceilings and leather surfaces, but because soft PVC contains softeners, it is easy to become brittle and difficult to store, so its scope of use is limited. Hard PVC does not contain softener, has good flexibility, is easy to shape, is not easy to be brittle, is non-toxic and has no pollution, and has a long storage time, so it has great development and use value.

PVC foam board has the characteristics of anti-corrosion, moisture-proof, mildew-proof, non-absorbent, drillable, sawable, planable, easy to thermoform, and hot tortuous processing, so it is widely used in furniture, cabinets, bathroom cabinets, exhibition shelves. , Box core layer, interior and exterior decoration, building materials, chemical industry and other fields, advertising, printing, silk screen, inkjet, computer lettering, electronic appearance product packaging and other occupations.

PVC hard 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 holder for medicine, chemical process holder; public Toilet water tank; various special-shaped products and containers such as templates, embellishment boards, exhaust ducts, equipment fabrics, etc. of processed products. It is an aspirational selection material for chemicals, building materials, decoration and other industries.

Relegated to second place in the late 1960s. Because PVC resin is composed of rich materials and low price, the demand is added quickly, and the position is gradually strengthened.
