ates and PC/ABS and PC/ASA blends in applications where neither brominated flame retardants nor perfluoro butyl sulphonates can be used. “The exceptional heat distortion and physical
properties of Nofia flame retardants have long been desirable in UL94 V-0 or VTM-0 [for film] formulations, but now processing is simpler, impact resistance is improved, and the new material offers the ability to meet the bluer shades of white required for certain brands of electronic equip- ment and electrical appliances,” the company says. “Polycarbonate has been a polymer of high

Extending in electronics The latest development from FRX Innovations — which has developed HFFRs based on phospho- nates and polyphosphonates for various polyesters (including polycarbonate) and polyurethanes — is a new Nofia product line that it says extends the performance of its copolymer flame retardants in to the consumer electronics and appliance indus- tries. Nofia CO6010-EX is the first in this family. The company says Nofia CO6010-EX — which
removes the need to dry the polymer before processing — targets a growing need for polycarbon-
interest,” according to Marc Lebel, CEO of FRX Innovations. “This is due to restrictions announced in Europe and the US on the future use of bromi- nated FRs in enclosures for TVs and monitors, and the high probability that those restrictions will soon be broadened to enclosures for most indoor electrical equipment.” FRX is developing other products based on technology similar to that used in Nofia CO6010- EX. It says future grades will offer enhanced properties for other polyesters and will present the opportunity for inherently flame-retardant resins with low colour transparency achieving VTM-0 (a
