Elimination of Chlorine- and Bromine-based Flame Retardants
The International Electrochemical Commission (IEC) has defined Halogen-Free with the following conditions:
- 900 ppm maximum Chlorine
- 900 ppm maximum Bromine
- 1500 ppm maximum total Halogens
This definition has been listed in the IEC standard 61249-2-21,
At this time, there is no legislative requirement for products to conform to a Halogen-Free requirement. We have a number of products using Halogen-Free plastics - PPS, LCP and Nylon (Polyamide) 4T compounds. However, there are currently still a number of Harwin products that cannot yet be classified as Halogen-Free, as Brominated Flame Retardants are still common in many Nylon (Polyamide) compounds.
Harwin are aware of this as one of the “Green” initiatives, and are considering our options on existing products and future developments. If you wish to know the halogen status on an existing product, please contact [email protected] for details.
