- RoHS 2.0Overview

RoHS（Restriction of Hazardous Substances）The directive aims to restrict the use of substances harmful to the environment and human health in electronic and electrical products. This instruction is2006year7moon1Officially implemented on the day, initially under control6Harmful substances, including lead（Pb）Mercury（Hg）Cadmium（Cd）Hexavalent chromium（Cr VI）Polybrominated biphenyls（PBBs）And polybrominated diphenyl ethers（PBDEs）.

RoHS 2.0It is an upgraded version of the original instruction, since2019year7moon22Formally implemented from [date], newly added4Phthalate esters:

Phthalic acid(2-Ethylhexyl)Ester（DEHP，CAS NO.: 117-81-7Limit value:0.1%）

Butyl benzyl phthalate（BBP，CAS NO.: 85-68-7Limit value:0.1%）

Dibutyl phthalate（DBP，CAS NO.: 84-74-2Limit value:0.1%）

Diisobutyl phthalate（DIBP，CAS NO.: 84-69-5Limit value:0.1%）

These substances are mainly used forPVCPlasticizers or additives in non polymers are widely used in electronic and electrical equipment such as cables, wires, coatings, adhesives, etc.
