Activities for Environmental Issues

Activities for Environmental Issues The Chemicals Division is working on environmental issues in accordance with our Environmental Guideline.

Introduction of products to reduce environmental impact manufactured by the Chemicals Division

ZEFFLE™ Infrared Reflective coating

Just painting this product on the roofs of factories or warehouses enables air conditioning systems to reduce its energy consumption. Fluoropolymers makes heat-shielding last longer consequently, it contributes reduction of CO2 emission by enesy saving.

UNIDYNE Multi Series™ Water & Oil Repellants DAIFREE™ Mold Releasing Agent

Chemicals Division introduced PFOA-free products to reduce environmental impact.
* PFOA-free is defined as below detectable levels (5ppb).

Activities by the Chemicals Division

This introduces the activities our company that are linked to the fluoro chemicals business.

1. Efforts being made to counter the effects of global warming

Daikin is taking action in the destruction of fluorocarbons, which have an impact on global warming.

2. Measures concerning use of PFOA

Daikin has completely ceased the manufacture and use of PFOA (perfluorooctanoic acid) and related substances, and manufacture of products which use PFOA and related substances as a raw material, as of the end of calendar year 2015.

In 2006, Daikin, as a part of its ongoing program for sustainable chemistry, joined the "PFOA 2010/2015 Stewardship Program" (a voluntary PFOA reduction program) together with seven other major fluorochemical companies. *1

During this program Daikin has developed and brought to the market a variety of alternative replacement products are therefore able to announce that, "Within the end-of-2015 deadline of the Stewardship Program we have ended all manufacture of PFOA and related substances."

*1 PFOA 2010/2015 Stewardship Program:
In January 2006, EPA invited the eight major fluoropolymer and telomer manufacturers to join in a global stewardship program with the following two goals:

1) To commit to achieve, no later than 2010, a 95 percent reduction, measured from a year 2000 baseline, in both facility emissions to all media and in product content, of PFOA its related compounds, and fluorocarbon telomers with more than 8 carbons.
2) To commit to working toward the elimination of these chemicals from emissions and products by 2015.

[The eight participating companies]
Arkema, Asahi Glass, BASF Corporation (successor to Ciba Specialty Chemicals), Chemours (successor to DuPont), Archroma (successor to Clariant), 3M/Dyneon, and Solvay Specialty Polymers (successor to Solvay Solexis), along with Daikin

Daikin will continue to give primary consideration to sustainable chemical management while developing new products. As an example, the company develops many new C6 telomer products, while subjecting them to a variety of health and environmental testing and, making the data from those tests publically available its web site.
