PFOA is a type of PFAS. The absence of PFOA alone cannot be considered PFAS-free (non-use).
Q: What is the difference between not using PFOA and being PFAS-free? A: PFOA is one of the substances included in PFAS. According to structural definitions, fluoropolymers such as PTFE and PFA are also included in PFAS, so simply stating that PFOA is not used does not mean that it is PFAS-free. For individual material verification, please inform us of the substances you are targeting and the necessary documentation based on your criteria, and consult with us in advance.
