Arkema worldwide


Through optimization of molecular weight and polymeric structure, Arkema has unlocked the full potential of a market historically limited to amorphous polymers. Using Kepstan® PEKK resin, it is now possible to produce large scale, deep drawn shapes with outstanding chemical, fire and thermomechanical resistance for aerospace, transportation, electronics, oil & gas, and many other demanding markets.

To effectively bring this technology to market, Arkema is working in close collaboration with Westlake Plastics (Pennsylvania, USA), an expert in high performance shape production, and specialty thermoformers CW Thomas (Pennsylvania, USA) and Plastiform (Thise, France). “We were experiencing thermoforming issues on thick gauges, as well as heat and chemical resistance limitations with existing materials,” explained Olivier Rodary, general manager, Plastiform. “By working together with Arkema on their Kepstan® PEKK material and by using a specific forming process together with engineered specialty toolings, we were able to achieve the forming of technical parts like never before. That will certainly help us to move several projects forward again,” commented Eric Lacker, technical manager, Plastiform.


Parts produced through this process will be demonstrated at the Arkema booth (Booth 6C57) at the upcoming K-2019 Fair in Dusseldorf, Germany, held from October 16-23.
