Restriction requirements for halogens and specific halogenated organic compounds

Halogen elements refer to non-metallic elements in the 7th main group of the periodic system, including five elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens generally exist in the form of compounds in people's daily lives, and they themselves have great toxicity. In combustion treatment, they can cause secondary pollution and produce highly toxic organic compounds such as dioxins. With the increasing call for "halogen-free", ROHS，REACH， Both Norwegian POHS and relevant regulations in various states of the United States have put forward restrictions on certain halogen compounds

Phthalate testing

Phthalates are a widely used class of artificially synthesized plastic plasticizers, which are widely used in toys, parenting products, food packaging materials, PVC materials, lubricants and personal care products (such as nail polish, soap, shampoo, etc.) At present, research has shown that phthalates can cause hormonal imbalances and affect the development of reproductive organs, affecting the normal development of fetuses or children. Therefore, we need to limit their use.

Dimethyl fumarate DMF

Dimethyl fumarate DMF is a chemical substance widely used in consumer goods, especially leather, textile products, electronic and electrical products, with significant bactericidal and antifungal effects. After contact with the human body, it can penetrate the skin, causing allergies, pain, dermatitis, erythema, and even respiratory distress.

Polycyclic aromatic hydrocarbons (PAHs)

Polycyclic aromatic hydrocarbons (PAHs) are a type of hydrocarbon with certain volatility, which can enter the human body through respiratory, skin, food, drinking water and other channels. Currently, there are 30 confirmed carcinogenic PAHs, among which benzo [a] pyrene (Bap) is a strong carcinogen, so there will be stricter restrictions on Bap.

The EU Waste Electrical and Electronic Equipment Directive 2002/96/EC, also known as the WEEE Directive, which came into effect on August 13, 2005, requires the responsibility of producers of discarded electronic products, such as providing a deposit for recycling, providing relevant product information to recycling centers, and registering and regularly declaring the quantity and recycling rate of products in the country where they are marketed. If the producer fails to assume corresponding responsibilities in accordance with the regulations of the corresponding member state, their products cannot enter the market of that country.

ROHS Solution

The Directive 2002/95/EC (ROHS Directive) on the Restriction of the Use of Certain Hazardous Substances in Electronic and Electrical Equipment, which came into effect on July 1, 2006, can be regarded as a "green revolution" in the electronics industry. Through this directive, people began to pay attention to the issue of hazardous substance control in electronic products for the first time. With the deepening understanding of the directive, the revision of the directive has also been put on the agenda. ROHS 2.0 (2011/65/EU), which came into effect on July 21, 2011, further revised the scope of control and exemption, and included HBCDD, DEHP, DBP, BBP in the priority control list. Starting from January 3rd, 2013, ROHS 2.0 will fully replace ROHS and be enforced.
