New proprietary processes enable infinite recycling of PSU, PPSU and PESU
Syensqo, a leading global provider of high-performance materials and chemical solutions, has announced another breakthrough in its 60 years history of sulfone polymers innovations with the invention of a proprietary chemical recycling technology that efficiently depolymerizes sulfone polymers to obtain purified raw material monomers. This new process enables the infinite circularity of sulfone polymers, confirming Syensqo’s leadership in sustainable specialty polymers.
The new technology builds on Syensqo’s sustainable ECHO sulfone polymers portfolio and relies on proprietary chemical recycling processes to break down formulated polyarylethersulfone (PAES) content in post-industrial production scrap (PIR) and post-consumer parts (PCR) into monomer feedstock for reuse in new polymer products. The purified monomers can be incorporated infinitely into Udel® PSU, Radel® PPSU or Veradel® PESU as well as other thermoplastics or even epoxy resin formulations without loss of performance.
By leading the transition to circularity within the PAES sector and engaging partners across the entire value chain, including collection, sorting and end-use, Syensqo is strengthening its pioneering role in life solution markets and welcomes the collaboration and support of the community in this endeavor.
