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.


Reducing Transpiration of Chemical Air Pollutants through Using Fluorochemical Products

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

Automobile Fuel Hose Made of Fluororesin

Automobile Fuel Hose Made of Fluororesin

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. Highly functional fluorine materials such as NEOFLON CPT are also beginning to see growing use in developed countries, where environmental regulations are increasing in scope and severity. Daikin aims to respond to the growing demand that will be created by these trends.
