This solution permits black and dark color polymers to be detected by near infrared (NIR) automatic sorting equipment, enabling subsequent recycling. OnColor NIR sortable black and dark colored solutions have been formulated to ensure black and dark packaging is detectable by current waste sorting equipment. The formulation used enables black packaging of various polymers to be sorted into the correct polymer stream, and sent for recycling instead of landfill or incineration, which is a key requirement of the circular economy system.

CUSTOM SOLUTION PROVIDES SIGNAL DAMPING AND HEAT RESISTANCE FOR ELECTRICAL CONNECTOR CASE STUDY: BERGAMID™ NYLON FORMULATIONS Challe nge Accepted. Traditionally, many connectors of this type are produced using liquid crystal polymers (LCPs) formulated with carbon fiber. After evaluating and approving the material’s physical properties, the manufacturer also requested that it was formulated to be flame-retardant.
