Compliance with Restrictions on Hazardous Chemicals

Daikin Green Procurement Guidelines (9th edition) Include RoHS 2 Restricted Substances in Specified Chemical Substances

The Daikin Group has a list of designated control substances that are restricted under the RoHS Directive*1, the REACH Regulation*2, and other laws. These are stated in our Green Procurement Guidelines and we work to prevent the presence of these chemicals in our products.

In the ninth edition of our Green Procurement Guidelines, published in January 2017, we added RoHS 2 restricted substances*3 as prohibited substances to our list of specified chemical substances.

*1 The RoHS Directive (Restriction of Hazardous Substances Directive) is a regulation in the EU prohibiting the use of certain hazardous substances in electrical and electronic equipment.

*2 The REACH Regulation on chemical substances went into effect in Europe in June 2007. REACH obligates companies manufacturing or importing at least 1 ton of chemical substances a year in the EU to register with EU authorities. REACH covers almost all chemicals on the market in the EU.

*3 From July 2019, four phthalate substances will be banned in the EU.

*1 The use of TBTs and TPTs is prohibited in the EU. Tin concentration must be 0.1% or less. The use of DBTs is prohibited in the EU. Tin concentration must by 0.1% or less. The use of DOTs is prohibited in the EU. However, only "Commodities that touch the skin" and "Two-component normal temperature cured sealing material" will be prohibited. Tin concentration must by 0.1% or less.

*2 Under the POPs Agreement of May 2009, PFOS was added to Appendix B (prohibited substances). In October 2009, PFOSs were added to the list of class I specific chemical substances under revisions to Japan's Law Concerning the Evaluation of Chemical Substances. Prohibited as of April 2010 under Japan's Law Concerning the Evaluation of Chemical Substances (except for applications in semiconductors, etching, and business photographic film).

*3 The use of F gas (HFC, PFC, etc.) is prohibited in one-component foams (banned in the EU starting on July 4, 2008.) However, the use of F gas (HFC, PFC, etc.) is permitted for refrigerants.

*4 Limited to applications in azo dyes and pigments which constitute the specific amines defined by the German Consumer Goods Ordinance and which come into contact with the human body for long hours (example: out surface of remote controllers).

*5 The use of HCFC for the production of foams shall be prohibited, and the use as refrigerants for Japan and EU models shall also be prohibited.

*6 Under a Commission Decision in March 2009 (2009/251/EC), products containing DMF are banned as of May 2009. DMF is used as an anti-fungal agent and in items such as packaging and leather products.

*7 Under the POPs agreement of May 2013, HBCD was added to Appendix A (prohibited substances). Since November 26, 2014, the Daikin Group has not used HBCD.

*8 Since June 1, 2014 (June 1, 2016 for certain applications) in Norway, it has been illegal to manufacture, import, and export consumer products containing specific PFOA.

*9 Under EU directive (EU) 2015/863 (March 31, 2015), four phthalate esters were added to the list of restricted substances. This goes into effect in the EU on July 22, 2019, but the Daikin Group will begin phasing these out in January 2019 in manufacturing covered by regulations.

*10 As of March 14, 2015, the manufacture, use, sale, distribution, and import of BNST and products containing BNST are prohibited under the Canadian Environmental Protection Act.

*11 Rubber or plastic components that come into direct as well as prolonged or short-term repetitive contact with the human skin or the oral cavity shall not contain more than 1 mg/kg (0.0001 % by weight of this component) of any of the PAHs.

*12 As of March 2, 2017 in the EU, it is illegal to use non-approved biocidal active substances.

Reducing Transpiration of Chemical Air Pollutants through Using Fluorochemical Products

In the Automotive Industry, Fluoride Materials Contribute to Reduced Leakage of VOCs

In the automotive industry, the movement is toward stricter regulations to prevent the leaking of air-polluting volatile organic compounds (VOCs) from gasoline and other substances.

NEOFLON CPT is a material for automobile fuel tubes and hoses that prevents permeation and leakage of VOCs in the hot engine surroundings. It reduces permeation to just one-fifth of Daikin's previous product, NEOFLON ETFE. And NEOFLON CPT adheres to polyamide resins and general purpose rubbers used to make conventional fuel hoses, meaning it can be used for laminated tubes. The DACS VOC processing device is a system that purifies air by breaking down, condensing, and oxidizing harmful substances in exhaust gases, such as VOCs and foul odors. It condenses and recovers highly pure organic solvents at a low cost, thus realizing purification of an entire air environment.

In China and other emerging countries where automobile production is on the rise, fluoride materials are replacing general-purpose materials to comply with stricter environmental regulations. Sales of highly functional fluorine materials such as NEOFLON CPT are rising every year in developed countries, where environmental regulations are increasing in scope and severity. Going forward, Daikin aims to respond to the growing demand that will be created by these trends.
