Many companies have their own specific direction of development and production technology in the field of film, but the following three kinds of film manufacturers occupy the respective market due to the fact that their film products have good production quality, long service life, or excellent product effect. Most of the shares stand at the top of the pyramid.
Today we briefly introduce the following three types of films:
3M - DBEF brightness enhancement film
DBEF using LED as a light source is an integral part of the LCD TV. It is especially used for low brightness compensation of LED TV edges.
3M has a strong patent advantage in this area and monopolizes 100% of the market share in this area.
Although many companies tried to produce their own DBEF, this did not bring about effective change. At present, 3M still firmly holds the monopoly of the DBEF market.
According to pre-holiday news, 3M and SKC signed an outsourcing contract. 3M has transformed from using its own patented production and supply of DBEF to the simultaneous sale of core products to external companies. 3M also signed contracts with companies in other countries for the sale of its core business.
If the companies referred to have established strategic partnerships with 3M companies and purchased 3M's core business, they can produce DBEF based on 3M's technology without having to pay additional royalties.
It is worth mentioning that it is not known whether 3M will lose its absolute monopoly on DBEF and give Korea's DBEF technology a chance to compete with it.
Kuraray - PVA optical film
The PVA film is highly transparent and is characterized by high orientation obtained by stretching. It is an important polarizer component that can meet the needs of larger size, higher resolution and thinner screens, and is used as a variety of products for liquid crystal displays such as LCD-TVs, PCs, tablet terminals and smart phones. s material.
At present, China's PVA film market is mainly monopolized by Japan's Kuraray, and Kuraray itself is one of the major suppliers of high-end PVA resin raw materials in the world.
According to Kuraray Data, currently, the supply of Kuraray PVA resin accounts for about 40% of the world, and the supply of PVA film for polarizers accounts for 80% of the global supply.
Kuraray's monopoly in the field of PVA optical films also benefits from its integrated production system, which enables the production of high-end PVA resins, production of PVA films for polarizers, and surface treatment of PVA films.
Kuraray Co., Ltd. was established on June 24, 1926 and is a famous comprehensive chemical industry group in Japan.
DuPont - PVF Film
DuPontTM Tedlar® PVF film backsheets have been used outdoors for more than 30 years under various climatic conditions (such as desert, tropical, coastal and alpine) and still provide critical long-term protection for components. System security and long-term benefits of photovoltaic systems.
DuPontTM Tedlar® PVF Films provide the best balance of weather resistance, adhesion, and mechanical strength - all of which are required to achieve long-term component life.
DuPontTM Tedlar® PVF film can be applied to two backplane structures. Both types of backplane structures have been commercialized and are currently used in photovoltaic modules around the world.
DuPontTM Tedlar® is the industry standard. Each backplane using this material is high performance and high standards.
Due to the close processing temperature and decomposition temperature of the PVF film, extremely high process control is required, and the investment is huge. This is the main reason that only DuPont can produce it, thus ensuring the reliability and consistency of the Tedlar® film product quality.
In 2014, DuPont and Airbus announced that they have signed a strategic supply agreement for DuPont Tedlar polyvinylidene fluoride (PVF) film products for the manufacture of EADS aviation products including Airbus.
DuPont Tedlar polyvinylidene fluoride (PVF) film brings maximum design flexibility to aerospace product manufacturing, creating a more attractive, easy-to-clean and wear-resistant cabin area.
The agreement stipulates that DuPont will supply Tedlar PVF film to all EADS contractors worldwide for a variety of applications in the aviation sector.
