Ticona, the technical polymers unit of Celanese AG, has expanded its North American compounding capability by adding 20% more capacity at its plant in Shelby, NC, and 30% more capacity at its plant in Florence, Kentucky, USA. The compounding facility in Shelby primarily creates glass-filled grades of polymers made at the site – Celanex®, Riteflex®, Vandar® and Impet® thermoplastic polyesters (PBT and PET) and Vectra® liquid crystal polymer (LCP) – and compounded grades of Fortron® polyphenylene sulfide (PPS) polymer made at Wilmington, NC. The specialty processing facility in Florence compounds glass, minerals and other additives with the company’s polyester, LCP and PPS products, as well as with Celcon® acetal copolymer and Celanese® nylon 6/6. In expanding their compounding capabilities, both sites added higher-throughput, higher-capacity twin-screw extruders. The extruder at the Florence facility replaced by the higher-volume machine is being used to provide greater colour concentrate production.
