The current situation and future development of EVA film

EVA film is no stranger to everyone now. Since 2002, the localization of EVA film has gone through 10 years and has gradually matured. It is a blessing for the glass film industry to develop from a single variety to a wide variety, from a single function to multi-function, from high price to low price, from affordable to popular by a few people, and from domestic to the world. I'm chenwujie from Zhejiang Yangming photovoltaic materials Co., Ltd. the following is my understanding of EVA film and industry development, and talk about my own views

★ what is eva glass film

eva laminated glass film: EVA film is a high viscosity film material sheet made of polymer resin (ethylene vinyl acetate copolymer) as the main raw material, adding special additives, and processed by special equipment. It is also called modified "EVA laminated glass film" in the industry. It has a strong adhesion to inorganic glass, and has the characteristics of toughness, transparency, temperature resistance, cold resistance, high bonding strength, high elongation at break, good moisture resistance and environmental protection. It is an ideal and economical bonding material for manufacturing safety laminated glass in the world at present, and can partially replace PVB materials for automotive, construction and decoration industries. The safety laminated glass produced with it can achieve the ideal effects of safety, heat preservation, wind resistance, impact resistance, sound insulation, UV protection and so on

★ historical track of EVA glass film

talk about my own understanding of the glass deep processing industry

at the beginning of the real localization of EVA film in 2002, glass deep-processing plants that tried EVA film were mainly concentrated in the north, Guangdong and Shanghai. At that time, the price of film was very high, and the price of deep-processing glass was also very high. It was mainly used in limited areas such as hotels, entertainment places, partitions of office buildings, etc

in 2006, with the emergence of several EVA glass film manufacturers in Nanjing and Guangzhou, EVA glass film appeared in a competitive situation, and the film price decreased; EVA laminated glass deep-processing plants have also emerged one after another, the corresponding glass market competition has also increased, the price of glass products has also been reduced correspondingly, and the application field and scope have been expanded, gradually developing from a first-class city to a second-class city

in 2008, due to the strengthening of the research and development of photo glass, the application scope of EVA glass film expanded to the sliding door glass industry, and developed rapidly, and the amount of film doubled

after 2010, more EVA glass film manufacturers have appeared in China, and the competition has reached white hot, showing a saturated state, and the competition is also extremely fierce. Film and deeply processed glass are facing the dilemma of becoming low-end products, but the application scope of film and deeply processed glass that can be directly sprayed with soft finish paint or coated with PVC film has developed to three-level cities, cities and even four level cities

since 2011, EVA film has been saturated with the decline of real estate, and many EVA film manufacturers and glass deep processing enterprises continue to face great market challenges

★ the current situation of EVA glass film

nowadays, EVA film is developing rapidly, from a single product to a variety of products, from monochrome to multicolor, from dyeing to natural color, from single function to multi-function, from high price to low price, from affordable products for a few people to popularization

at present, EVA films commonly seen in the market include the following:

reinforced decorative glass EVA films: widely used in glass single-sided reinforcement, reinforced glass sliding doors, sliding doors, swing doors, reinforced glass wardrobe doors, reinforced glass cabinet doors, etc

Putuo laminated glass EVA film: it is widely used in double-sided laminated glass with silk and silk, and is suitable for home decoration, hotel, hotel and KTV decoration

high permeability laminated glass EVA film: widely used in the construction industry, such as office glass curtain wall, balcony guardrail, daylighting roof, sunshine room, canopy and a series of outdoor buildings

white and color laminated glass EVA film: widely used in interior decoration, KTV teahouses, cafes, bars, dance halls, business halls, home decoration, studios, wall lights, sales departments, stores, villas, stair floor glass, etc

5. Anti aging ability: excellent formulation system, perfect combination of all additives, addition amount of all additives, completely appropriate, so that the main reaction is sufficient, there is no residual additives, reduce the formation of side reactions, and prevent the formation of adverse groups

purpose and scope of use of the product: Glass Industry: used for laminated glass in outdoor buildings, bulletproof glass, and indoor high-end family decorative glass

future development of EVA film

at present, PVB film still occupies an irreplaceable leading position in the construction industry, with a market share of more than 80%, which is an opportunity and a challenge for our EVA film manufacturers

we still have a lot to do to ensure the healthy development of the industry and avoid unfair and vicious competition. Next, let me talk about my personal views:

1. The polarization of the film market will become more and more obvious in the future. Enterprises with R & D technology, perfect management system and abundant funds will move towards the high-end market; There are also some enterprises that occupy a certain market share in the way of small profits but quick turnover. Both the former and the latter are indispensable to the market, but how to break through their respective bottlenecks and achieve greater development depends on the market concept of operators and continuous innovation of products

2. Formulate industry standards and standardize industry behavior. Under the guidance of correct and standard behavior, let our EVA film industry develop healthily

3. Develop new application fields of products, constantly develop and innovate, let enterprises take the path of diversified development, and ensure the steady development of the industry

4. Strengthen the internal management of the enterprise, improve the internal quality supervision system, and strengthen the enterprise's own product testing ability and acceptance means to ensure the stability and development of product quality

5. Strengthen technical support and process guidance for glass deep processing enterprises, and improve and comprehensively develop their product applications

the development of the industry and the progress of the enterprise are inseparable from: ① the market concept of the operator, ② the R & D ability of the technical team, ③ the stability of product quality, and ④ the joint efforts of colleagues in the industry. I believe that our EVA film will go further as long as there are standardized industrial behaviors to protect us
