Lead (Pb), examples of the use of the substance: solder, glass, pvc stabilizers;
2. Cadmium (Cd), examples of the use of the substance: switches, springs, connectors, housings and pcb, contacts, batteries;
3. Mercury (Hg), (mercury), examples of the use of the substance: thermostats, sensors, switches and relays, light bulbs;
4. Hexavalent chromium (Cr6+), Examples of use of the substance: metal-attached corrosion coatings;
5. Polybrominated biphenyls (PBBs), Examples of use of the substance: Flame retardants, pcb, connectors, plastic housings;
6. Polybrominated diphenyl ethers (PBDEs), Examples of use of the substance: Flame retardants, pcb, connectors, plastic housings;
7. Diisobutyl phthalate (DIBP), used as a plasticizer for PVC, can be used as a substitute for DBP, also used as a plasticizer for cellulose resin, vinyl resin, nitrile rubber and neoprene rubber.
8. Phthalic acid (2-ethylhexyl ester) (DEHP), mainly used as PVC plasticizers, PVC in electrical and electronic equipment used as insulators such as cables and wires. A small amount of DEHP is used in other non-polymer applications, such as ceramics for electronics or electrolyte for capacitors
9. Dibutyl phthalate (DBP), mainly used in conjunction with other plasticizers, is used in PVC components such as cables, sockets, tubes, vibration dampeners, and is also used in a number of non-polymers, such as paints, adhesives, sealants and printing inks.
10. Butyl benzyl phthalate (BBP), mainly used as a plasticizer in PVC flooring, in electrical and electronic equipment may be present in synthetic leather, textile coatings, PVC materials, printing inks, sealants and adhesives.
The EU Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (The Restriction of the use of certain Hazardous substances in Electrical and Electronic Equipment).
The core content of the RoHS Directive is to restrict the use of hazardous substances in electrical and electronic equipment, to protect the environment, to provide green consumption, and to realize the extermination and non-hazardousness in the two areas of production and consumption.
