The engineering team conferred with Avient to find a material that could meet the stringent requirements.

For instance, Avient engineers successfully used 100% PCR PET in composite unidirectional tapes and laminates, and PCR nylon 6 from reclaimed fishing nets in a LFT composite.

Although PVC is one option, this manufacturer needed a colorable, drop-in replacement for PC/ABS. THE SOLUTION The manufacturer approached Avient with its challenge. From there, the Avient team identified material options that offered high flame retardancy and finally, requirements for processing flexibility and colorability were applied.
