Halogen-Free Plastics

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.

PVC (Polyvinyl Chloride) is currently used on a small selection of our pre-cabled assemblies, purely in the cable insulation (not in the connector product) - these include:

  • M40 series (1mm pitch) pre-crimped contacts
  • Archer IDC (1.27mm pitch) ribbon cable assemblies

 

Harwin are aware of the reduction of halogenated products 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.
