KLUBERBETA RM 47-291

Special grease for elastomers and plastics.

As a manufacturer of pneumatic systems you expect valves to operate smoothly at both high and low temperatures. You therefore need a grease that is compatible with the materials used and also has a wide service temperature range. Klüberbeta RM 47-291 is a special grease enabling smooth component operation at low temperature and offering high thermal stability. It is based on silicone oils and contains a lithium soap thickener. Due to its specific consistency, it shows good backflow behaviour into the lubrication gap.

Its shows notably good compatibility with many elastomers (except silicone rubber) and plastics.

Klüberbeta RM 47-291 is primarily used for the lubrication of sealing elastomers. In such applications it attains minimum friction coefficients even at low temperatures. The product also shows good compatibility with a multitude of materials and good stability at high temperatures.
Exemplary fields of application are O-ring seals in pneumatic equipment in cars.
Klüberbeta RM 47-291was developed for the lubrication of elastomers and plastics. However, due to the great variety of materials in the market, we recommend checking the compatibility with the materials in contact, especially prior to series application.
Klüberbeta RM 47-291 can be applied by grease gun, brush, spatula or using automatic systems.

Longer component life due to

low friction coefficients across a wide service temperature range
good compatibility with elastomers and plastics

Simple handling enabled by good wetting of functional surfaces
