Article-No: 090020 Special lubricating grease for the lubrication of sensitive plastics and elastomers

BARRIERTA L 25 DL is based on perfluorinated polyether oil and PTFE and thus resistant to many media such as water or hydrocarbons.

Do you need to attain low friction coefficients in elastomer/metal or plastic/plastic friction points over a long time and across a wide temperature range? BARRIERTA L 25 DL can help you keep friction low even at temperatures of -25 °C, especially when lubricating seals in train doors. This will enable you to meet requirements for low pressure variations in trains going through tunnels and constant actuating forces for doors over a wide temperature range.

For train door seals, which might come into contact with passengers' clothes, BARRIERTA L 25 DL SPRAY is particularly beneficial because it can be applied in a very thin lubricant film. This helps prevent the contamination of passengers with lubricant while enabling any trapped pieces of clothes to be pulled free with a minimum of force.

Do your customers expect a long service life of seals, even if they are frequently exposed to direct sunlight? BARRIERTA L 25 DL absorbs some of the sunlight's UV radiation, keeping the seal pliant for longer.

Do you need a lubricant that is compatible with sensitive materials? Field experience has shown the product's good compatibility with many sensitive plastic materials such as PC, or with elastomers such as EPDM.

Do you have optical applications requiring a lubricant that does not form a condensate on lenses? With the low vapour pressure of its base oil, BARRIERTA L 25 DL offers what it takes to prevent the formation of condensates.


Benefits for your application

  • Compatibility with plastics and elastomers, e.g. EPDM or silicone elastomers Low friction forces in plastic/plastic and elastomer/metal combinations

  • Good water resistance

  • Slower ageing of elastomers exposed to sunlight

  • BARRIERTA L 25 DL SPRAY can be applied in particularly thin layers, requiring only a minimum of time.
