PFPE Lubricants-Perfluoropolyethers-CHANGLU FLUOROCHEMICALS_Perfluoropolyether (PFPE), Hydrofluoroether (HFE), Perfluoroketone (PFK)
PFPE Lubricants are long-chain fluoropolymers consisting of fluorine, carbon and oxygen atoms, the average molecular weight is between 1000～16000. PFPEs are the best choice for high or wide-temperature range applications, harsh or aggressive chemical environments, high vacuum, radiation resistance or other high performance lubricant applications.
Key Benefits
• Environmentally safe, Zero ozone depletion potential;
• Non–toxic behavior;
• Non-flammable,
• Excellent thermal resistance, No volatile organic chemicals, Low evaporation loss, can be used up to 300℃;
• Unmatched chemical and solvent resistance, Inert to liquid and gaseous oxygen;
• Non–reactive with metal, plastic, elastomers and rubber;
• Good viscosity index;
• Extremely wide operating temperature range;
• Excellent electrical resistance, etc.
