Primary Chemistry:
InfinX MRO KFMS3 is a perfluoropolyether (PFPE) industrial fluid recommended for use in extreme operating conditions with temperatures up to 300°C.
InfinX MRO KFMS3 is a PFPE-based lubricating grease formulated with PTFE thickeners and anticorrosion additives for extreme service environments where safety, reliability, and chemical inertness are critical. Designed to perform across a broad temperature range of -40°C (-22°F) to 260°C (500°F), it provides excellent lubrication stability under continuous operation while resisting radiation, fuel, and hydrocarbons. InfinX MRO KFMS3 is non-toxic, non-flammable, oxygen-safe, and offers high load-carrying capacity, making it suitable for demanding applications in aerospace, aviation, vacuum systems, semiconductors, process instrumentation, and more.
