SUMICO Sumitec F931 High-Temperature Chemical-Resistant Fluorine Grease
Sumitec F931 is a fluorine grease developed by Sumico Lubricant Co., Ltd. It uses a chemically stable fluorinated oil as the base oil and fluororesin (PTFE) as the thickener, providing excellent stability and long-term lubrication performance. The grease provides excellent resistance to heat, chemicals, solvents and oxidation, making it suitable for applications where conventional lubricating greases cannot maintain stable performance. Sumitec F931 is a white grease with approximately NLGI No.2 consistency (worked penetration 300). It can be used over a wide temperature range of approximately -20°C to +250°C and is suitable for high-temperature bearings, sliding parts and precision mechanical components.
