Ticona Intros Eco FR Polyesters
July 21, 2008 |Estimated reading time: 1 minute
FLORENCE, Ky. Ticona Engineering Polymers, the engineering polymers business of Celanese Corporation, added two Riteflex thermoplastic polyester elastomer (TPC-ET) grades to its portfolio of XFR halogen-free flame-retardant polyesters for use in eco-friendly applications.
Ticona uses a halogen- and antimony-free flame-retardant system in its XFR product line to replace conventional FRs. The system reportedly enhances the performance of the engineering polymers while making them more eco-friendly. The new Riteflex XFR grades are Riteflex XFR 440 (Shore D hardness of 40) and Riteflex XFR 655 (Shore D hardness of 55). They are said to offer UL-94 V-0 flame retardance rating at a minimum thickness of 1.5 mm for all colors; a comparative tracking index greater than 600 V; high tensile elongation properties; excellent elastomeric property profile for applications that require enhanced toughness; and good processability.
"Continuing the halogen-free direction Ticona started in thermoplastic polyester (PBT) with Celanex XFR, we designed our two new Riteflex XFR grades to help customers comply with anticipated hazardous substance restrictions and waste directives," said Pete Bombik, Polyester Global Business director for Ticona. He refers to regulations such as RoHS and WEEE that restrict the use of brominated flame retardants (FR) in electrical and electronic applications. The plastics industry is evaluating alternate flame-retardant additives for use in electrical and electronic applications that face stringent FR requirements, he added.
