Ticona announces enhancement to its XFR® halogen free FR polymers

08-Nov-08

Ticona Engineering Polymers have announced an addition to its portfolio of XFR® halogen-free flame retardant polymers - the enhanced Celanex® 6842 series with improved processability and equivalent properties that give designers and manufacturers a "drop-in" option for use in eco-friendly electrical and electronic components. The new Celanex XFR polymers comply to V-0 and RoHS standards with a proprietary flame retardant (FR) system which will allow direct replacement for most similarly available PBTs without having to modify designs, build new molds or make significant tooling changes. Requested by Ticona customers, the enhanced series builds on the halogen-free direction it started when the Celanex XFR range of non-halogenated FR thermoplastic polyesters was commercialized in 2004. This FR system, recognized in 2006 with a Frost & Sullivan Product Innovation Award, is also included in two new Riteflex® XFR thermoplastic polyester elastomer (TPC-ET) grades. Celanex XFR and Riteflex XFR grades are compliant with hazardous substance restrictions and waste directives such as the Restriction ofHazardous Substances Directive (RoHS) and the Waste Electrical and Electronic Equipment Directive (WEEE). As per the company, the new Celanex PBT series with its patented XFR system provides several advantages over the highest performing non-halogenated FR polyesters including: · No migration during processing or corrosion of terminals or leads during use · No toxic / corrosive gases emitted when burned · Lower density than halogenated FR system · Excellent electrical properties (high ComparativeTracking Index and Glow Wire) · Excellent colorability and color stability
