EOF Eltinert F Oil
The Eltinert series of contact lubricants have been developed to provide superior protection to electrical contacts under the most difficult conditions. These include extended periods at high temperatures and under corrosive chemical atmospheres. They are also ideal for the protection of noble metals, either in switches or connectors. EOF is an oil version suitable for applications with high insertion forces. Temperature Range (°C) -25 to +300
Dielectric Constant (1 MHz) 2.1
Dielectric Strength (kV/mm ASTM D877/67 @ 250°C) 40
RoHS Compliant (2015/863/EU): Yes
- Oil version; ideal for use in applications with high insertion forces
- Excellent electrical characteristics combined with very good plastics compatibility
- Excellent oxidation and chemical resistance; high protection in harsh environments
- Prevents and cures high contact resistance caused by silicone contamination
Typical Product Applications
Eltinert F Oil is suitable for contacts requiring thin films of lubricants or to provide assistance with high insertion forces. A diluted oil version (DOF) for surfaces requiring very thin films of lubricant is also available. For greater environmental protection Eltinert F Grease (EGF) is recommended.
The polar nature of these lubricants ensures good bonding to all metals, including gold. Although gold itself is not subject to environmental attack, gold plate is porous and attack can occur on the substrate metals, e.g. silver, copper or tin. Eltinert F prevents this attack and can allow the use of thinner gold plate.
Eltinert F fluorinated lubricants have two main areas of application:
1. As contact lubricants - particularly suitable for contacts involving gold and/or aggressive environments e.g., printed circuit edge connectors, plug connectors, rotary and sliding switches.
2. For the lubrication of plastics and rubbers, including those known to be particularly prone to solvent stress cracking.
The following plastics, normally regarded as prone to solvent stress cracking, are unaffected by Eltinert F at 70°C: 'Noryl' (PPO/Polystyrene), Polystyrene, Impact modified polystyrene, ABS, Polycarbonate.
The following vulcanised rubbers showed minimal change in properties at 70°C: Natural rubber, EPDM, SBR, Butadiene-acrylonitrile, Butyl.
