Users should independently evaluate the material for its suitability in specific applications. Users should independently evaluate the material for its suitability in specific applications. These formulations are ideal for applications in various industries, including consumer products, electronics, transportation, and industrial equipment.

These advanced, customizable formulations are ISO 10993 compliant, compatible with gamma, autoclave, or EtO sterilization, and come in pre- colored or natural grades. KEY CHARACTERISTICS • Excellent chemical resistance • Low moisture uptake • Comparable dimensional stability to nylon • Reinforced with 10–33% glass fill • High impact and wear resistance • Eco-conscious alternative to PA66 and PA6 MARKETS & APPLICATIONS Whether using a standard or customized formulation, the PK-based Trilliant grades provide a high-performing, cost-competitive, and more eco-conscious alternative to competitive materials found in biopharmaceutical processing, hospital settings, and home healthcare applications. Processing conditions can cause material properties to shift from the values stated in the information.
