FRX promotes phosphorous-based polymer for FR applicationsFRX promotes phosphorous-based polymer for FR applications

(Chelmsford, MA) is proposing an answer to concerns about halogen-based flame retardants (FR) in the form of a phosphorous-derived inherently-flame-retardant polymer. FRX, which says halogen-containing FR additives represent more than 60% of the current market demand, is ramping up production of a polyphosphonate polymer it says is inherently flame retardant and transparent, while offering high flow and utilizing polycondensation production methods applied for polycarbonate (PC) and polyester, which lower its production costs.
