Syensqo, a global leader in advanced performance materials and chemical solutions, announces the expansion of its pioneering Non-Fluorosurfactant (NFS) perfluoroelastomer (FFKM) portfolio with new high-temperature grades.

These innovative materials are engineered to deliver exceptional sealing performance in the most demanding environments, while supporting the industry’s transition to more sustainable solutions.

Building on its legacy of scientific exploration, Syensqo’s latest NFS FFKM grades offer continuous operating temperatures up to 320°C, surpassing the capabilities of conventional FFKMs. With a newly developed curative that’s designed to withstand extreme heat, these grades deliver unmatched purity and reliability at high temperatures without the need for particle-causing fillers.

The new high-temperature NFS FFKM grades are designed for high purity, high temperature vacuum applications, exhibiting excellent resistance to fluorine, oxygen, and hydrogen plasmas. Their low stiction and high reliability make them particularly well-suited for gate and isolation valve applications, reducing maintenance and downtime for customers.

"The introduction of our new high temperature NFS FFKM resin represents Syensqo's biggest leap in elastomer technical capabilities in nearly a decade," says Andrew Lau, Senior Executive Vice President of Electronics & Industrial at Syensqo Specialty Polymers GBU.

"By enabling new, higher temperature processes and decreasing downtime for mature processes, Syensqo continues to bring innovation and value to our customers, while also prioritizing advancements in sustainability."

Manufactured in Spinetta, Italy, Syensqo’s new NFS FFKM portfolio is the result of a multi-year research effort dedicated to advancing both performance and environmental responsibility.
