Halogen Testing Service
Halogen is widely used in EE products, housing, adhesive, and so on.Whereas after the halogen compounds included electronic waste and plastics products burnt, may easy to result from so-called century poison-Dioxin-like Compounds, bring about the harm to health via the accumulation of organism. The international companies announced the Halogen-Free Standards in the end of 2006, clearly defined the Halogen-Free (Cl, Br) requirements within the products. Based on the IEC 61249-2-21:2003 standard. Per the IEC standard, restrictions on halogens apply only to Chlorine (Cl), Bromine (Br), and their compounds. No other halogen (Fluorine, Iodine, Astatine) is regulated.
Fluorine (F)
- Lemon yellow gas (F2), highly-corrosive, violent oxidizer, easy to make a chemical combination with other elements, and results from a large number of thermal energy
- Application:HF production, insecticide NaF production, plastic production, such as PTFE, Teflon, PFA, FEP, and so on
Chlorine (Cl)
- Green gas, violent oxidizer, easy to excite the human respiratory tract mucous membrane, may result in death when under critical condition.
- Application:Disinfectant and bleach production
Bromine (Br)
- Brown liquid results in serious harm when the skin has contact with it.
- Application:Disinfectant and bleach production, the flame retardant for plastic, radiocontrast agent, preservative, deodorant, and so on.
Iodine (I)
- Purple solid, the necessary trace elements within the organism.
- Application:iodine tincture production, filament production
Astatine (At)
- Solid, the artificial radioactive element.
