setral® PFPE Lubrications for Extreme Requirements

PFPE (perfluoropolyethers) are very stable and inert chemical substances which, in the right chemical composition, produce an extremely inert material with excellent lubricating properties. Unlike conventional mineral-, synthetic- or silicone-based greases, PFPE lubricants do not fail at low or very high temperatures. Furthermore, they withstand aggressive media such as highly concentrated alkalis, acids, gases and cleaning agents and also have a long-term effect. This makes them the right lubricant for lifetime lubrication, which is particularly important for sensitive materials such as plastics, elastomers and wear-prone sliding couples. They ensure functionality, safety and quality in individual components, assemblies or manufacturing processes, while accounting for less than 0.015% of the total lubricant market. They also open up new possibilities in design and application for enormous cost-saving potential.

Typical applications for PFPE lubricants include metal and/or plastic sliding couples, plain/roller bearings, guide rails, valves, seals, fittings, and electrical contacts, among others, in the following industries:

setral® PFPE lubricants have high resistances:

• High pressure resistance
• High oxidation stability
• High radiation resistance
• High vacuum resistance
• High temperature stability partially more than +300°C
• High chemical resistance, even against aggressive media such as acids and lye

  

setral® PFPE lubricants guarantee excellent compatibilities:

• Outstanding material compatibility, even with different material combinations
• Compatible with almost every common plastics
• Compatible with most seals (except fluorinated rubber)
• No swelling, shrinking, hardening, softening or embrittlement of seals

setral® PFPE lubricants show optimum physical properties:

• Low surface tension creates excellent, thin and even surface wetting
• Low vapor pressure results in very low evaporation losses
• Low setting point implies good low temperature characteristics
• Excellent lubricity reduces friction coefficient and energy input
• Good dielectric characteristics
• No flash point
• High viscosity index
• Transparent and odorless

setral® PFPE lubricants ensure safety in application:

• Non-inflammable
• Not labeling according to ordination of hazardous substances (GefStoffV)
• Partially with international H1 registration for the food industry
• Physiologically harmless
• Perfectly suited for life time lubricant
• Extremely long re-lubrication intervals compared to conventional lubricants

setral® offers over 70 PFPE based greases and oils and is always developing new lubricants
