An expanded portfolio of sustainable engineering resin compounds, containing at least 50% recycled content, is being highlighted by Polymer Resources. Initially, the company’s portfolio of such sustainable materials was comprised of four general-purpose grades, but as it approaches mid-2024, the portfolio is being expanded to include several flame-retardant products listed by Underwriters Laboratories (UL).

The company’s initial commercial offering included a low-flow PC (PC-GP1S), a medium-flow PC (PC-GP2S), a high-flow PC (PC-GP3S) and a PC/ABS (GP1S). With at least 50% recycled content, all are opaque and available in natural, black or custom colors. The properties and processing parameters of these grades are said to be very similar to those of their virgin counterparts, making it possible, in many cases, to use these sustainable materials as drop-in replacements for existing fossil-based resins. This is also the case with the FR compounds added to the expanded portfolio.
