In what fields PVB film application? Construction and the industry to new USES of increased use of glass, lead to all kinds of needed? Great color, this company offer? 10 kinds of basic? Color for your choice, through basic colors? Numerous kinds of us can get? Color. Coloured film? With a width of 950 mm below small glass, to satisfy the need for special color, you will we? You are also proposed.

PVB laminated glass membrane is made of polyvinyl butyral resin, after plasticizer DHA plasticizing extruding and forming a kind of polymer material. PVB interlayer glass film thickness is commonly two 0.38 mm and 0.76 mm, the inorganic glass have good cohesiveness, with transparent, heat-resistant, cold resistant, resistant to wet and mechanical strength higher characteristic. Laminated glass can be used for insulating glass Windows and doors. Ordinary insulating glass generally have no impact resistance, while one side for the laminated glass insulating glass into safety glass. According to different purposes, laminated glass can be divided into flat laminated glass, curved laminated glass, bulletproof glass, laminated glass and laminated glass for decoration of guard against theft. Mainly used for sandwich glass, PVB film is safe, heat preservation, noise control and isolation of multiple functions such as uv, widely used in construction, automotive and other industries.

Because the laminated glass has very high impact strength and the use of security, and thus is applicable to the structure of the door, window, ceiling, floor and wall, industrial workshop of the skylight, shop Windows, kindergartens, schools, stadiums, private houses, villas, lunatic asylum, Banks, jewelry shops, such as the post office keep valuables or fragile glass building doors and Windows, etc. Laminated glass is often used in schools, airports, hotels, ministry offices and other public facilities, prone to accident place (French Windows, glass doors, etc.) and the place such as roof window.

Laminated glass is widely used building doors and Windows, floor, wall, ceiling skylights. Bending of laminated glass can be used to lift sightseeing elevator, revolving door of the hotel. Bullet-proof glass and security glass can be used in Banks, securities companies, insurance companies and other financial enterprises business hall and gold and silver jewelry store, museums, commercial grade residential buildings, prisons and other places of the counter, doors and Windows. Adopts special formula in the production of PVB film in aerospace, military, and high and new technology industry and other fields have a wide range of applications, such as used in aircraft, spacecraft, military equipment, solar cells and solar receiver, the composite damping steel plates and other applications in industrial fields.

PVB film is a kind of PVB as the plasticization of the base film, mainly for the production of sandwich safety glass. After a long period of research and development, PVB has good purity and transparency, light stability and strong glass glue and sex. PVB film can absorb almost 100% of the ultraviolet ray, with its production of laminated glass is mainly used in automobile and building two fields.

Sinochem dispatch of new wear-resistant high safety coefficient, good sound insulation effect of polyvinyl butyral (PVB) film after it is widely used in automobile and construction, in recent years, and opened up a new application space in the field of photovoltaic panels. If growth consulting companies in the United States, the stern Sullivan in analysis and prediction of research report, published in May, in the next few years, PVB film demand growth, market growth potential is tremendous.

Threshold high industry concentration

PVB mainly for the automotive and construction industry manufacturing laminated safety glass, namely the PVB resin first pressed into thin film, and then embedded in between the glass to make laminated glass plate. Safety glass in the interlayer materials to absorb impact energy, and the material sound insulation effect is good, resistance to ultraviolet light. At present, about 89% PVB used in the production of construction and automotive safety glass, 4% in photovoltaic materials, the rest of the 7% used in the paint, glue, dye and other materials. 2008, global consumption of PVB resin for 270000 tons, the market size of about $2.2 billion, with the stern Sullivan, expects demand in the future this product every year will increase to 6% average annual growth rate, consumption will reach 410000 tons by 2015. In 2009, the market value of about $1.524 billion of global PVB film, expect the market to 7.9% a year growth rate increased rapidly.

PVB manufacturer mainly has four - solutia, Sekisui, dupont and Kuraray, they account for 96% of market share. Solutia is one of the biggest manufacturers, its products are mainly used in automobiles and construction. Sekisui's products are mainly used in automobile industry, Kuraray and dupont, has an important position in the emerging photovoltaic material application, but dupont cars and construction industry is facing the loss of market share.

Because PVB film industry needs large capital input, the mature technology and integration of production process of raw materials, so the higher threshold. Currently, there is no other product to replace PVB film, although ionomer may pose a threat to it in the future, but now the cost is too high.

Is application of a large car market

The car industry is one of the biggest PVB film terminal customers. Safety glass is mainly used in automobile windshield. Auto industry safety standards are very strict, so the safety glass is a big demand. In Europe, the government has forced people to use safety glass. According to statistics, in 2009 the market value of automotive PVB film was about $818 million. Relevant organizations, expects the market will increase to 6.5% average annual growth in the future.

In addition to use in the windshield of the car, PVB film can also be used in the edge of the window. Removable side window must be very wear-resisting, currently used by most of the removable glass material is still fragile, safe enough, so the mobile side window using safety glass in the future will be more and more, and the car's rear window and is developing towards the trend.

Construction dosage was 80%

PVB film as the sandwich materials embedded in the safe glass, mainly used in office building, the dosage of this part of PVB film in 80% of the total amount. In 2009, the consumption of the global construction industry PVB film of 89000 tons, generated $614 million in sales. Although already on the market at present useful ionic crosslinking polymer made of glass, but it is only for special users, mainly used in the Windows of the hurricane.

At present, many factors promote the application of PVB film in the construction industry. Some government issued measures mandatory residential building use safe glass, PVB sheet with good sound insulation effect and its performance are wear-resistant heat-resistant promoted the demand of safety glass. But if the future cost of ionomer dropped significantly, it is likely to become the threat of PVB products.

Photovoltaic (pv) has good application prospect in the market

PVB film in photovoltaic panels are mainly used as sealing material. Photovoltaic panels is the feature of long life, generally up to 20 years, and manufacturing chamber of commerce in a variety of means to prolong the life of the panels, sealing material is a good choice. Sealing material solar cells and photovoltaic panels can be firmly sticking to the surface, so that we can make the photovoltaic cells under high temperature and strong ultraviolet radiation also can maintain stable performance. Sealing material of panels cost 3% ~ 5%.

At present, there are two main types of photovoltaic panels with sealant, elastomers and thermoplastics. EVA as a kind of elastomer material, in the sealant market occupies the largest share, PVB as thermoplastic material, market share, second only to EVA.
