Daikin Industries: Fluorochemical Products


Fluorine compounds are engineering materials used in many different fields and applications, from everyday electronic products to industrial materials such as materials used to manufacture semiconductor products, automobiles, and architectural structures.

Daikin Industries has been a pioneer in the product development and manufacturing of fluorine compounds in Japan. The company is perhaps better known as one of the world’s foremost manufacturers of air conditioners, (→Daikin Industries: Air Conditioners for Commercial Use )but it also has a long-standing reputation as one of the leading companies working in fluorine compounds and fluorochemicals today. In 1933, Daikin Industries succeeded in manufacturing fluorocarbons, and from 1942 onwards was using proprietary technology for mass production. Since then, the company has made available more than 1800 different fluorine products to international markets.

Fluorine compounds have high resistance to heat as well as high chemical resistance. They repel water and oil alike, and are abhesive. These properties are exploited in a wide range of industrial and everyday products alike.

Today, Daikin Chemicals Division is involved in the development and production of an extremely diverse line-up of fluorine compound–based products. These include resin materials, rubber materials, chemicals, lubricants, refrigerants for refrigerators and air conditioners, cleaning agents for precision electronics components, coating agents, fiber treatments, additives, mold releasing agents, and films. Put simply, wherever there is demand, Daikin Chemicals Division is working on a solution.

Fluorine Technology: Contributing to Conserving the World’s Environment

At present, Daikin Chemicals Division is working on the development of applications for fluorine-based functionalities that can contribute to efforts to conserve our natural environment in the following four fields: gas, cell materials, coating materials, and LCD displays.

For example, ZEFFLETM is an infrared reflective coating that works as a thermal barrier. By painting it to the roof of a building, the coating will reflect the sun’s rays, and prevent heat from entering the building, thereby suppressing the rise of internal temperature. Daikin Industries test have shown that the internal temperature in buildings with ZEFFLETM treated roofs were 5°C lower than that in buildings with untreated roofs. Coating the roofs of industrial plants and buildings with ZEFFLETM can therefore lead to significant reductions in the levels of electricity for air conditioning systems. Moreover, thanks to the properties of fluorine compounds, the coating is much more resistant to degradation and rusting than other similar coatings. Internal tests have shown that the coating effects can last between 15 to 20 years. 

Daikin Industries is also developing materials for biofuels and fuel cells that exploit the outstanding properties of fluorine compounds, such as their ability to prevent fuel leakage, and their heat resistance and durability.

Fluorine Electrolytes: Committed to Contributing to Energy Innovation

In 2011, Daikin announced plans to develop and sell a fluorine-based electrolyte for electric double layer capacitors, or EDLCs, which fall into an area—accumulator devices—of significant potential market growth. The company has positioned the fluorine electrolyte as a core growth product and will be aiming to have secured steady growth by 2015.

EDLCs are built into a wide range of devices, for example as the memory back-up power source for mobile devices, the uninterruptible power supply for computers, or the power storage device for photovoltaic generation equipment. A survey by JMR Science indicated that the EDLC market’s current global worth is around 50 billion yen (~600 million US dollars), and that there is further potential for growth through further applications in such areas as electric cars, hybrid vehicles, wind power generators, and photovoltaic generators.

The use of fluorine-based electrolytes makes it possible to produce a commercially viable EDLC that can operate stably at a 3 V, which is higher than the normal operating voltage of conventional EDLCs. This increase to 3 V means that energy density can be improved by 40% in comparison to the 2.5-V EDLCs currently generally available.

Going forward, demand for EDLC is expected to increase, which suggests positive growth for Daikin’s fluorine electrolyte.

Exceptional technological prowess is the backbone of any manufacturer. Daikin Industries has 80 years of experience in the development and refinement of fluorine compound and fluorochemical-related technology, and it is this experience that will drive future progress. Looking to international markets, emerging nations represent a clear source of increasing demand for industrial and everyday products. Daikin Industries’ seemingly limitless vision for the developmental possibilities of fluorine technology—matched only by the seemingly limitless functions of fluorine—is sure to guarantee the company a flourishing global future.
