Flame Retardant Compounds/Additives for Electronic Devices

SpecialChem / Jun 6, 2007

A ban on fire retardants that were identified as posing health, safety and environmental risks, was initiated by the European Commission. Part of the European Union (EU) Directive on the Restriction of Certain Hazardous Substances (RoHS) bans certain brominated flame retardants (PBB [poly-bromine biphenyl]; PBDE [penta-bromodiphenyl ether]). While the Western Europe restriction, which applies to products that currently enter the market, is not expected to spread substantially to other regions, the use of BDE found in many flame retardants has also been restricted in some U.S. states including California, Michigan, and Oregon. With restrictions coming into effect this year a number of masterbatch producers and plastics resin suppliers have responded by introducing halogen free flame retardant (FR) compound grades. Flame retardant additives have to be carefully chosen to meet the desired standards without adversely affecting other polymer properties. Clariant Masterbatches has developed three non-halogenated FR masterbatch products coined CESA-flam®.
