RoHS stands for Restriction of Hazardous Substances, a directive that restricts the use of certain hazardous materials in electrical and electronic products. ESD, on the other hand, stands for Electrostatic Discharge, which is a phenomenon that can damage electronic components.

ESD mats are used to prevent the build-up of static electricity on a work surface, which can damage sensitive electronic components. RoHS 2.0 ESD mats are designed to comply with the RoHS 2.0 directive, meaning they do not contain any of the restricted substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), or polybrominated diphenyl ethers (PBDEs).
