Compliance with Restrictions on Hazardous Chemicals

Daikin Green Procurement Guidelines List Designated Control Substances to Prevent the Presence of These Chemicals in Our Products

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.

*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.

  • EU REACH Regulation (SVHC: substances of very high concern) group (Prohibited materials specified by this guideline are excluded) *14

*1 Use of TBTs and TPTs is prohibited in the EU market. Tin threshold Level is less than 0.1 Use of DBTs is prohibited in the EU market. Tin threshold Level is less than 0.1 Use of DOTs is prohibited in the EU market. However, the only applications that are prohibited are for "Commodities that touch the skin" and "Two-component normal temperature silicone modules." Tin threshold Level is less than 0.1

*2 PFOSs were added to Appendix B by POPs agreement at COP4 in May 2009.
The Japanese "Law Concerning the Examination and Regulation of Manufacture, etc. of Chemical Substances" was revised in October 2009, and PFOSs were added to Class I Specified Chemical Substances. Use is prohibited after April 2010.
PFOSs used in ①production of etching resist, ②production of the resist for semiconductors, ③production for films for professional uses are excluded from the prohibition.

*3 Use of F-gas (HFC,PFC, etc) is prohibited in one-component foams (EU ban starting from Jul. 2008)Use of F-gas (HFC,PFC, etc.) is exceptionally permitted for refrigerant.

*4 Applied to use in which the human body is in contact for a long time with the azo colorants and colors which form specific amine as defined in 76/769/EEC (example: outer shell of the remote control unit ).

*5 Use of HCFC in the production of foams and as refrigerants for Japan and EU models is prohibited.

*6 By an EU Commission decision (2009/251/EC) on 17 March 2009, products containing Dimethylfumarate (DMF) shall not be placed on the market after 1 May 2009. DMF had been used as a fungicide for packing and leather goods, etc. The allowable concentration is 0.1 mg/kg or less.

*7 HBCDs were added to Annex A (Abolition) of the Stockholm Convention on Persistent Organic Pollutants (POPs Convention) at the Sixth Conference of the Parties in May 2013. Prohibition in the Daikin Group started from 26 November 2014, except where the national implementation of the Stockholm convention results in a deviation of the implementation timing.

*8 After 1 June 2014, manufacturing, importing, exporting and selling of consumer products that contain PFOAs are prohibited in Norway. (Some of the applications are prohibited after 1 January 2016.) Under the REACH regulation, it will be regulated from 4 July, 2020, but the prohibition for the production of regulated parts by the law in the Daikin group started from 1st January 2019.

*9 Four phthalate substances were added to RoHS restricted substances by an EU amendment directive ((EU) 2015/863) on 31 March 2015. These substances are mainly used in polyvinyl chloride (PVC) and rubber as plasticizers. The implementation date of this EU directive is on 22 July 2019, but the prohibition for the production of regulated parts by the law in the Daikin group started from 1st January 2019. Prohibition timing for the production of non-regulated parts by the law depends on discussion individually.

*10 Rubber or plastic components that come into direct contact 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) for any of the PAHs.

*11 After 1 March 2017, use of biocidal active substances for EEA (EU, Republic of Iceland, Norway and Liechtenstein) products is prohibited when they have not been approved or when an application for approval was not submitted by 1 September 2016 in the EU depending on the intended use of substances (referred as Product Type).

*12 Some of PVC whose substitution is available is subjected to reduction.

*13 Regarding the management of nickel, if there is a possibility for the nickel to come into contact with human body for long hours

*14 All SVHC that will be added in the future shall be managed. A postscript is not added.

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.
