Teijin PFAS-Free Resin Targets Automotive Sliding Parts

Teijin Develops New PFAS-Free PPS Resin

Teijin Limited has developed a new high-performance resin that is free of perfluoroalkyl and polyfluoroalkyl substances (PFAS), with the company anticipating applications including automotive parts. The Teijin PFAS-free resin has been added to the SOLFIGA polyphenylene sulfide (PPS) resin sliding parts grade, expanding the product family with a formulation designed for applications requiring sliding properties and wear resistance. The development comes as PFAS regulations continue to tighten in markets around the world, increasing attention on alternatives to fluorine-based resins. Teijin said the new material is intended to address replacement demand in automobiles, industrial machines, and electrical and electronic devices where durable sliding performance is required.

Two Reinforced Resin Types Added

The new PFAS-free resin is available in two reinforcement configurations: a carbon fiber reinforced type and an aramid fiber reinforced type. Both are part of Teijin Limited's SOLFIGA PPS resin sliding parts grade, positioning the materials for applications where wear resistance and sliding characteristics are important. The use of fiber reinforcement provides distinct material configurations within the new grade while maintaining the product's PFAS-free positioning. This development is particularly relevant to component manufacturers seeking alternatives to fluorine resins without moving away from engineering resin solutions designed for demanding mechanical applications.

Applications Extend Across Multiple Industries

Teijin Limited expects the material to be considered for automotive parts as well as components used in industrial machines and electrical and electronic devices. These applications can require materials that withstand repeated contact, friction, and wear while maintaining suitable sliding performance. By adding the PFAS-free formulation to its SOLFIGA PPS portfolio, Teijin is addressing a specific material substitution need created by the global regulatory trend surrounding PFAS. The company is targeting applications in which fluorine resins have traditionally been used because of their sliding and wear-resistance characteristics, making material compatibility and performance important factors for potential adoption.

Industry Impact & Outlook

The development gives Teijin a PFAS-free option within its PPS resin portfolio as manufacturers evaluate replacements for fluorine resins in sliding components. For the automotive industry, potential use in parts could become relevant as suppliers respond to changing material requirements and regulatory expectations. Industrial machinery and electrical and electronic equipment manufacturers face the same broader need to identify suitable alternatives for applications that depend on sliding properties and wear resistance. The next step for adoption will depend on application-specific evaluation and customer requirements, including whether the carbon fiber or aramid fiber reinforced type provides the required performance for each component.
