Klüber BARRIERTA I EL-102 High-temperature PTFE Grease 50g tube

Klüber BARRIERTA I EL-102 is a high-temperature grease based on PFPE and thickened with PTFE, specifically developed for long-term lubrication in demanding industrial applications—from microelectronics to mechanical engineering.Outstanding protection up to 180 °CResistant to aggressive chemicals and vaporsExcellent compatibility with plastics and elastomersPack size: 50 g tube (Item no. 0900082794)Also available in: 1 kg tinApplication AreasRolling and plain bearings operating at elevated temperatureBARRIERTA I greases attain long service lives when used in rolling and plain bearings operating under high thermal stress.The fine thickener and the high oil content enable smooth running of bearings also at high speeds and ensure a long life of the lubricated components.Typical fields of application are infilm stretcherstextile stenter framesprecision engineeringclean-room engineering (e.g. microchip manufacture)The low vapour pressures of BARRIERTA I greases make them also recommendable for use in fine to ultra-high vacuum. Electrical contactsBARRIERTA I EL-102 and BARRIERTA I MI-202 have proven successful for the long-term lubrication of electrical contacts in high and medium-voltage switchboards. Component tests have shown that plug and unplug forces are consistent without unduly influencing transition resistance. There are no known decomposition productsthat would have an insulating effect on the contacts.Behaviour towards plastics and elastomers BARRIERTA I greases of all viscosity grades are widely neutral towards elastomers and plastics (possible exception: highlyfluorinated rubber). Nevertheless, compatibility with the materials should be tested, especially prior to series application.Benefits for Your ApplicationLong-term availability and service life of componentsover a wide service temperature range up to 260°Cwhen exposed to aggressive chemical agents and vapourswhen using sensitive plastic materialsTried and tested over many years in numerous industries and component typesdue to BARRIERTA base oils, which are made specifically to enable long-term stabilitybacked by a large number of approvals and referencesdue to availability in 4 different viscosity grades to suit various applicationsTechnical DataItem no.0900082794Chemical base (oil)PFPEChemical base (thickener)PTFEMin. service temperature-45 °CMax. service temperature180 °CColorWhiteDensity at 20 °Capprox. 1.92 g/cm³NLGI grade2Shear viscosity at 25 °C3,000 – 5,600 mPasBase oil viscosity at 40 °Capprox. 100 mm²/sBase oil viscosity at 100 °Capprox. 12 mm²/sCorrosion protection (EMCOR)≤ 1Flow pressure at -40 °C≤ 1,400 mbarVKA welding forceapprox. 4,800 NSpeed factor (n x dm)approx. 500,000 mm/minMinimum shelf life60 monthsApplication InstructionsFor best results, clean the lubrication point with solvent 180/210, followed by Klüberalfa XZ 3-1. Ensure the surface is metal-bright and free of particles. BARRIERTA I EL-102 is approved for contactless micro-dosing (≥0.1 mg) in electropneumatic jet valves. Information on product safety (Manufacturer, Contact)KLÜBER LUBRICATION MÜNCHEN GMBH & CO.
