Avient Corporation announces an expansion to its range of polyketone (PK) based materials with new Complēt PKE long fiber reinforced engineered thermoplastics. The new formulations broaden options for customers looking for strong mechanical performance to support demanding applications, even in cold environments.   

Joining Edgetek PKE and LubriOne PKE materials launched in 2021, Complēt PKE formulations can provide alternatives to nylon (PA) and acetal (POM) based formulations, offering added supply security and sustainable benefits. 

“This development represents a proactive response to demands from our customers in oil & gas, transportation, and industrial industries looking for next-generation engineered materials with a property retention as low as -22°F for pipes, tubing, fluid management, and more,” said Eric Wollan, general manager, PlastiComp at Avient.

Complēt PKE formulations can provide alternatives to PA and POM based formulations.

Complēt PKE formulations are semi-crystalline and deliver excellent chemical resistance, low moisture uptake, and dimensional stability similar to nylon (PA66).

When compared to alternatives during standard testing, these materials can help reduce carbon footprint over the product lifecycle, producing 61% less CO₂ than PA66, 46% less than PA6, and 30% less than POM.

Grades are available with 30% - 50% long glass fiber, allowing customers to request customized performance requirements for certain applications. They are especially useful in applications in chemical, fuel contact, and high-moisture environments that benefit from chemical and hydrolysis resistance.
