About Environmental Activities 画像1

Worldwide efforts to reduce the use of substances of concern move ahead in considering the life’s diversity. The substances of concern are specified in laws, industry groups and the green procurement standard of each company in Japan too. Our company doesn’t use RoHS 6 substances in our products purposely in grasping raw materials of rubber sheets. Our company will respond to amendments flexibly, in watching the laws, industrial groups and green procurement guideline of companies.


●Conform to the RoHS Directive and ELV Directive(*1)

■Our company doesn’t use the substances specified in RoHS Directive and ELV Directive purposely as raw materials of rubber sheets.
■Our company will submit you an evidence report of the fluorescent X-ray analysis depending on your needs.

●About other laws and regulations

REACH Regulation(*2) went into effect in June 2007 in Europe. It is examined to add new substances of concern to existing RoHS Directive and ELV Directive. Countries promote the strengthening of laws and regulations, so regulated substances are assumed to increase in the future. Therefore, Industry associations and each company have implemented the development and the update of the Green Procurement Standards.
Heretofore our company reduces and monitors chemical substances which are expected to be regulated, grasping the details of raw material of rubber sheet. For some general –purpose products, our company doesn't use purposely the following chemical substances which are expected to be regulated in the future.


・PCB: Polychlorobiphenyl.
・PFOA: Perfluorooctanoic acid and its salts.
・PFOS:Perfluorooctane sulfonates.
・Deca-BDE:Decabromodiphenyl ether.

For substances of very high concern (SVHC) under the REACH regulation, substances are added approximately once every six months.
Please consult us as it is necessary to investigate whether it is compatible or not with each update.
