Classification by applicationThickener: PFPE + PTFE
Cryogenic Greases
Lubrication at ultra-low temperatures — from −60°C to −196°C — LNG, aerospace and cryogenics
Cryogenic greases based on PFPE (perfluoropolyether) with PTFE thickener for the lubrication of mechanisms operating below −50°C, down to −196°C (liquid nitrogen) and beyond. At these temperatures, conventional mineral and synthetic oils solidify completely — only PFPE maintains its fluidity and lubricating capacity. Applications in LNG plants, cryogenic storage systems for oxygen and nitrogen, rocket valve and satellite mechanisms, and magnetic resonance imaging (MRI) equipment.
