Phthalates

Phthalates are used as plasticizers for polymer materials such as plastics, are commonly used in electrical electronic, toys, food packaging materials, medical blood bags hoses, vinyl flooring wallpaper, cleaning agents, Lubricants, personal care products (such as nail polish, hair sprays, soaps, shampoos) other hundreds of products, but because they play a role similar to estrogen in humans animals, they can interfere with endocrine affect the human body. There are serious health hazards. Therefore, countries strictly control it.  

polycyclic aromatic hydrocarbons

On July 1, 2015, the new stard AfPS GS 2014:01 PAK for polycyclic aromatic hydrocarbons for German GS certified products officially came into effect, while the original stard ZEK 01.4-08 expired on June 30. Electronic electrical products, toys, food contact materials, plastic products, rubber products, machinery other products that need to apply for German GS certification must meet the new PAHs test requirements. On September 15, 2019, the German Product Safety Commission (AfPS) released the new stard AfPS GS 2019:01 PAK for the evaluation testing of polycyclic aromatic hydrocarbons in GS certification. The new stard will be implemented on July 1, 2020.

halogen

Halogens in electrical electronic products generally include fluorine (F), chlorine (Cl), bromine (Br), iodine (I). The advantages of halogen are flame retardant, easy to dissolve, high reactivity, so it is often used in flame retardant, refrigerant, organic chemical raw material, bleaching agent, wool degreasing agent, etc. Application of halogen in electronic electrical products: halogen flame retardant. Common halogen flame retardants include polybrominated biphenyls, polybrominated diphenyl ethers, tetrabromobisphenol A, polychlorinated biphenyls, polychlorinated terphenyls, polychlorinated naphthalenes, hexabromocyclododecane, short-chain chloroparaffins, etc.

Other hazardous substances

a. Heavy metals

Electronic electrical products, such as wires, coatings, circuit boards, etc., are full of heavy metals, which are difficult to be biodegraded. On the contrary, they can be enriched hundreds of times by the biological amplification of the food chain, finally enter The human body often causes allergies damages the user’s liver, kidneys nervous system. Therefore, heavy metal control in electronic electrical products is particularly strict.　&Nbsp;

b. Asbestos

Asbestos (Asbestos) is a general term for natural fibrous siliceous minerals. It belongs to silicate. It is a substance with a fibrous crystal structure. It contains oxides such as magnesium, iron, aluminum, sodium. Bound silica. Asbestos fibers are dispersed in the air in the of dust are inhaled into the human body, they adhere deposit in the lungs, causing organ cancer.

In 2009, China implemented the "Methods for the Determination of Asbestos Content in Products" (GB/T 23263-2009), which is suitable for the determination of asbestos content in construction materials, friction materials, sealing materials, insulation materials non-metallic minerals. The 1999/77/EC directive issued by the European Union in 1999 clearly restricted the use of six types of asbestos, crocidolite, amosite, chrysotile, anthophyllite, actinic asbestos, tremolite asbestos, it has now been included in Annex XVII of the REACH Regulation. The United States has restricted the use of asbestos since 1971, completely banned the production use of asbestos asbestos products in 1992. Japan has completely banned the use of asbestos products since 2008.

c. PFOS

The European Union’s restriction on perfluorooctane sulfonic acid (PFOS) was included in the EU REACH Regulation Annex XVII restriction list in 2009, later due to (EU) No 757 /2010 on the EU persistent organic pollutants The POPs regulations were revised higher restrictions were put forward. The restrictions in REACH were eted in 2011.

d. EU POPs regulation requirements for PFOS

• Substance or mixture: PFOS≤10 mg/kg

• Items (including finished products, semi-finished products their parts): PFOS≤1000 mg/kg

• Textiles or other covering materials: PFOS in the covering material <1µg/m2
