my country’s PVB interlayer film production is gradually increasing, and it is expected to realize domestic substitution of high-end products

PVB interlayer film, also known as PVB film, is mainly a polymer material film that is plasticized and extruded by polyvinyl butyral resin under the catalysis of strong acid. The appearance is a translucent film with a relatively smooth surface. , has good softness and certain roughness. PVB interlayer film has good adhesion to inorganic glass and has the advantages of transparency, heat resistance, cold resistance, and high mechanical strength. It is the best adhesive material for the production of laminated glass. In addition, PVB interlayer films are also widely used in building curtain walls, showcases, bulletproof glass and other fields.

At present, my country’s PVB interlayer film industry chain is very mature. The upstream of the industry chain is mainly the raw material industry, which provides raw materials such as butyraldehyde, PVA resin, plasticizers, etc.; the midstream is mainly the PVB interlayer film production industry, which is responsible for the production and manufacturing of PVB interlayer films. link; the downstream is mainly oriented to application fields, and is mostly used to produce photovoltaic components, automotive laminated glass, architectural laminated glass, etc., and is ultimately used in automobiles, photovoltaic power generation, construction and other fields.

From the perspective of market segment structure, my country’s PVB interlayer film is dominated by the automotive market, accounting for 48.2% of the overall market; followed by the construction field, accounting for 29.1%; ranking third is the photovoltaic field, with a market share of The proportion is 15.3%.

According to the “China PVB Intermediate Film Market Analysis and Development Prospects Research Report 2023-2027” released by the Industrial Research Center, in recent years In 2017, my country’s economic level continued to improve, residents’ consumption power gradually increased, and automobile production costs gradually decreased, product prices were gradually accepted by consumers, and market penetration rate gradually increased. According to data released by the China Association of Automobile Manufacturers, in 2022, my country’s automobile production and sales will complete 27.021 million units and 26.864 million units respectively, a year-on-year increase of 3.4% and 2.1% respectively. As an important component in vehicle production, the market for automotive laminated glass has gradually grown. As the downstream market demand for automotive laminated glass in my country continues to grow, its production has continued to increase. As the main raw material for the production of automotive laminated glass, the market of PVB interlayer film has also been positively affected. Against this background, my country’s PVB interlayer film production has gradually increased. In 2022, my country’s PVB interlayer film production will be 814,000 tons, a year-on-year increase of 4.9%.

Industry analysts said that at this stage, there are a large number of companies in my country’s PVB interlayer film market, and foreign companies mainly include Kuraray and Mann. Siyi, Solutia, Sekisui, DuPont, etc., domestic companies mainly include Wanwei High-tech, Deste, Jichang New Materials, Dongcai Technology, Jiantao Specialty Resin, Liyang New Materials, etc. Foreign PVB interlayer film companies have almost monopolized my country’s high-end market due to their relatively advanced production technology. Domestic PVB interlayer film companies are mainly concentrated in the mid-to-low-end market due to relatively backward production technology. As my country’s PVB interlayer film companies continue to carry out product research and development, production technology has gradually improved, and the gap with foreign advanced technology has gradually narrowed. In the future, it is expected to realize domestic substitution of high-end products.
