Performance benefits, PA66 shortage driving increased bio-based plastics use in automotive

Despite the clear sustainability benefits, for many years bio-based plastics have struggled to grow beyond a few niche applications in the automotive industry.

However, this is starting to change as automakers discover some of the unique performance characteristics a bio-based resin can provide versus more traditional materials.

Recently, we joined Composites World magazine to discuss this trend, as well as the growing use of bio-based resins for composite applications, particularly those using unidirectional tapes.

Envalior’s EcoPaXX line of PA410 bio-based engineering plastics uses the castor bean to leverage a carbon-neutral feedstock while providing the following unique benefits:

  • Cost comparable: As a global PA66 shortage continues, EcoPaXX offers a sustainable alternative that doesn’t sacrifice performance.
  • Saves weight: Since EcoPaXX maintains its strength during aging, this enables thin-walled parts that reduce weight by 30% over alternatives such as PA66.
  • Utilize existing tooling: With EcoPaXX, there is no need to invest in new tooling since it can be molded using the same processes as PA66.
  • Resists moisture: EcoPaXX absorbs 30% less moisture than PA66 and even 40% less than PA66, offering additional benefits over traditional polyamides in terms of dimensional stability and hydrolysis resistance.
