FRX Polymers, Inc (FRX), the Massachusetts-based manufacturer of environmentally friendly inherently flame retardant plastic, recently inked an agreement with Uhde Inventa-Fischer (UIF) to build and operate a pilot plant facility at UIF's Domat/Ems Switzerland facility. The agreement with UIF will allow FRX to quickly achieve commercial scale for its line of patented polyphosphonate homopolymers and copolymers, which are produced via a polymerization process known as the melt-phase polycondensation. Fuether, this will allow FRX to increase the production in the range of 500 tpa by early 2010. Uhde Inventa-Fischer, a subsidiary of Uhde GmbH, is one of the world leaders in technology and equipment for the production of polyester and polyamide polymers like PET, PBT, PA-6 and PLA.
Currently, FRX produces the polymers at its pilot plant located in Chelmsford, MA. FRX's family of polyphosphonate homopolymers and copolymers, the company claims, are tough, transparent, possess high melt flow, and are inherently flame retardant and environmentally friendly (non-halogenated). Due to FRX Polymer's high molecular weight, they do not migrate out of the host plastic when used as flame retardant additives. In addition to delivering excellent flame retardant properties, they also typically improve melt flow and mechanical properties in engineering plastic formulations.
