PEF-70/110

Description

perfluoropolyether PEF – good lubricity PET combined with low volatility allows them to be used in various fields, especially in aircraft, rocket, vacuum technology and other aggressive environments

Vacuum Technology PES are ideal for use as a diffusion pump fluids, lubricants and working fluids in vacuum pumps, for example, in semiconductor fabrication. Also, PEF are used for compressors and valves operating in corrosive environments (halogens, gaseous acids, etc.), as a lubricant for centrifuges in the production of uranium.

In aviation, rocket PES can be used as lubricants in extreme conditions, for example, in jet engines, high temperature turbine engines and satellite devices.

perfluoropolyethers thickened with particulate polytetrafluoroethylene is used as greases, particularly in the aerospace field.

Foreign counterparts PET used in lubricants for the mechanism of hours of such well-known firms like Rolex, as well as in lubricants for medical devices.

Excellent thermal stability in combination with dielectric properties makes PEF ideal for use as dielectric liquids as lubricants to sliding electric contacts and switches. The advantage of PEF to silicone oils is the lack of hard deposits at high voltage arcing.

In electronics PET can be used as electrical insulating fluids and coolants.
The low surface energy and high stability of PEF makes them excellent protection stone material, in particular for easily breakable limestone bricks. Good results in this area provide the functionality PEF (acids, alcohols). PEF penetrate into the pores and prevent the infiltration of water, thereby contributing to conservation structures.

The unique properties of the perfluoropolyethers and their derivatives makes them very attractive for a wide range of consumers. The only and very serious obstacle to the dissemination of data of liquids is their high cost. However, the insolubility of PET in common solvents, and water resistance to chemical, thermal and radiation aggression provides a long-term operation, thereby recoup the cost of their purchase.
