Long Fiber Polyketone Formulations

Complēt™ PKE Formulations 

Improve Chemical Resistance, Reduce Carbon Footprint 

Complēt™ PKE polyketone formulations are long glass fiber reinforced Polyketone solutions for structural applications using metal today. These materials are semi-crystalline and deliver excellent chemical resistance, low moisture uptake, and dimensional stability similar to nylon (PA6 and PA66). Polyketone has lower coefficient of friction, similar to Acetal, giving it improved wear resistance. 
These formulations also offer over 2x higher impact properties than short fiber reinforced, polyketone solutions and, further, maintain impact properties in cold and demanding environments making them ideal candidates for outdoor applications. 
Complēt PKE formulations offer a reduced carbon footprint as a result of the base resin helping to improve sustainability over the end product lifecycle.  Manufacturing polyketone results in 61% less carbon dioxide (CO2) than producing PA66 and 46% less than PA6. 
These materials are for use in applications in moisture-rich environments or for applications in which chemical resistance or cold impact performance is critical.  Market examples include Industrial (pipes, tubing, fluid management), Electrical & Electronics (connectors, battery components), Transportation (under-the-hood fuel/ chemical contact components), and Oil & Gas.
