The development of EVA film market in China mainly shows the following characteristics:
(1) the technical progress of domestic EVA film manufacturing enterprises is obvious, and the product performance is gradually improved
With the increase of investment in R & D of EVA film in China in recent years, the performance of domestic EVA film products has been improved, and the gap between domestic products and foreign products has been further reduced.
(two) the scale of the industry is expanding rapidly, and some dealers show the trend of extending to the industrial chain
With the rapid development of solar energy industry in China, the demand for EVA film market is expanding rapidly, and the EVA film manufacturing industry has also set off a surge in capacity expansion. For example, Hangzhou Forster as the industry leading enterprises, the new 40 EVA film production line, the annual output is expected to exceed 80 million square meters; Henan Sikeda invest 120 million launched EVA film project, completed its annual output is expected to exceed 350 million yuan; Zhejiang, Zhejiang Feiyu neutrality, ikang science and Technology (002610, shares) and other companies have also announced the expansion of production.
In addition, in the process of expanding the market scale, enterprises originally engaged in the sale of foreign EVA film products began to introduce independent production technology, and realize the transformation from "dealer" to "production and marketing integration".
(three) the trend of using capital market to promote the development of the industry is gradually emerging
In recent years, with the rapid development of EVA film market and development prospect of solar photovoltaic optimistic estimates, many investors began to intervene in the real PV manufacturing sector, with the development of solar photovoltaic manufacturing industry encountered temporary difficulties, some investors also began to look to the field of manufacturing photovoltaic auxiliary materials. Industry enterprises also began to gradually use the power of the capital market to speed up technological progress and expand the scale of enterprises.
In 2005, Li Lianchun of the South China University of Technology and other successful preparation of B228 type EVA film heat aging properties and visible light transmittance were better, and the production cost is lower than the same quality of foreign products; in 2009, Wenzhou Ruyang photovoltaic materials Co. Ltd and DuPont Co developed "Redford REVAX" EVA film, and by the domestic authority quality inspection agency inspection, the film after 1000 hours of UV aging test after transmittance keeping rate of more than 99%, the yellowing index is less than 2, reached the international level; in addition, Hangzhou, Zhejiang, Shenzhen, Forster Feiyu Skoda and other major domestic EVA film production enterprises continue through technological progress to improve product performance, raise the stakes for further market share.
(four) with the development of technology and the rapid development of EVA film enterprises in China, the market price of EVA film will still show a downward trend
With the EVA upstream raw material supply enterprises monopoly advantages continue to lose, EVA plastic film raw material prices will be down. As of 2010, EVA masterbatch equivalent to 10.56-12 yuan per square meter price. At present, the domestic price is only half of the imported products do not have to, with the number of domestic EVA film production enterprises continue to increase, foreign enterprises market and technology advantages will continue to weaken, the EVA market price will tend to reduce the cost, and promote the production and application of solar energy components continued to decline.
