Fomblin® PFPE fluids are an ideal choice as lubricants and functional fluids in the chemical process industry. Fomblin fluids offer extremely high resistance to aggressive chemicals, excellent flow properties over a wide range of temperatures, and good lubricity.
The physical and chemical properties of Fomblin PFPE-based greases make them suitable for use in chemical plants where lubricating parts are subjected to very wide thermal cycles. Typical applications include lubrication of roller bearings of conveyor belts, air/dry compressor crankshafts, valves, valves stems, and seals operating at high air pressure.
Oxygen producers and users in chemical and metallurgical industries have been using Fomblin for years with excellent technical and economic results as well as a substantial improvement in safety conditions. Bundesanstalt fur Materialprufung, Berlin (BAM), has approved the use of Fomblin fluids, specialty lubricants, and greases in the presence of oxygen.
Algoflon® L PTFE micropowders are ideal for dispersing in greases to improve both high and low temperature lubricity. When added to high viscosity specialty greases, service life and lubricity are improved, especially in high temperature and corrosive environments. Greases incorporating Algoflon L PTFE micropowders are effective for much longer periods than conventiional greases so that lubrication frequency may be reduced substantially.
Another important role of Algoflon L PTFE micropowders in greases is as thickeners. For this purpose PTFE micronized powders with a high specific surface area are preferred. In fact, the higher the specific surface area of the PTFE micropowders, the lower the quantity requested to obtain the desired properties, in particular, the increase in viscosity and grease consistency (lower penetration).
Additionally, extreme environmental demands on greases, such as those experienced in the chemical industry (i.e. wide temperature ranges and heavy loads) can be accommodated by the inclusion of Algoflon L PTFE micropowders.
Anti-seizing oils for systems that can have long periods of inactivity (safety valves and taps) can contain very high loadings of Polymist® PTFE micropowders in order to guarantee fail-safe security.
