Attention is focused on fluorine resin alternatives. Characteristics and applicability of PFAS-free material PEEK resin.
Due to the strengthening of PFAS regulations centered in Europe, there is a growing interest in "non-fluorinated materials" within the manufacturing industry. Among these, PEEK resin, a type of super engineering plastic, is gaining attention. PEEK resin is a material that does not contain PFAS, yet it possesses high heat resistance, wear resistance, mechanical strength, and chemical resistance, making it a candidate for alternative materials to fluoropolymer. However, it cannot completely replace the excellent non-stick and low-friction properties of fluoropolymers, so appropriate selection based on usage conditions is important. This article will explain the relationship between PFAS regulations and PEEK resin, as well as its characteristics as an alternative material.

basic information
PEEK resin is a non-fluorinated super engineering plastic that is gaining attention as a material less affected by PFAS regulations. It has high heat resistance in the range of 250 to 260°C and demonstrates excellent resistance to many chemicals and organic solvents. Additionally, it excels in mechanical strength and wear resistance, maintaining stable performance even in high-load and high-temperature environments. On the other hand, the "extremely high non-stick properties" and "ultra-low friction" that fluorinated resins are known for can be challenging to achieve with PEEK alone. Therefore, when promoting PFAS-free alternatives, it is important to clarify "what needs to be replaced" and "what performance is required" in order to select the appropriate materials.

Applications/Examples of results
PEEK resin is utilized in applications where there is a desire to balance compliance with PFAS regulations and high durability. For example, in sliding components, it is used to extend lifespan through improved wear resistance; in high-temperature transport components, it ensures stability in high-temperature environments; and in chemical equipment, it is adopted for corrosion prevention against chemical liquids. Additionally, our PEEK coating "PEEKCOAT" contributes to the longevity of equipment and reduction of maintenance by forming a film of PEEK on metal substrates, imparting wear resistance, chemical resistance, and insulation properties. In considering PFAS-free alternatives, there have been successful applications even in cases where "traditional fluoropolymers lack durability" and "there is a need to accommodate high-load environments."

Company information
Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
