What is the difference between PTFE and PFA? Considerations for selecting ETFE coatings.
Fluororesin coating ETFE coating
Practical fluororesin coating chosen for its performance balance.
When selecting fluoropolymer coatings, ETFE is characterized by its "balanced" properties compared to materials like PTFE and PFA. While it may not match PTFE or PFA in terms of non-stickiness and chemical resistance, it excels in wear resistance and impact resistance, demonstrating stable performance in more practical environments. Additionally, it has excellent processability, allowing for thick film applications and secondary processing, which is a design advantage. It is a suitable option for needs such as "wanting to ensure durability while avoiding excessive specifications" and "considering a longer-lasting coating." We are also available for consultations, comparisons, and prototype evaluations from the material selection stage, so please feel free to contact us regarding technical inquiries and prototype verification.

basic information
ETFE (ethylene-tetrafluoroethylene copolymer) is a material that excels in mechanical strength and durability among fluoropolymers. It features chemical resistance, weather resistance, and electrical insulation, while also demonstrating excellent abrasion resistance and impact resistance. Due to its melt flow properties, it allows for stable film formation and can accommodate thick coatings and secondary processing. It also possesses non-stick and slip properties, providing a balanced performance tailored to various applications.

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.
