Fomblin® AR555


Product Overview

Fomblin® AR555 (now known as Klübertemp GR AR 555) is a homogenous white grease having excellent rust inhibiting and solvent washout resistance properties.

Fomblin® AR555 is suitable for lubricating mechanical parts requiring boundary ( extreme pressure ) lubricating properties. Fomblin® AR555 is suitable for use in severe operating conditions, high load, high speed and where a wide temperature range is required. Fomblin® AR555’s operating temperature range is from – 20˚C to 250˚C. Its properties make it suitable in ‘lubricating for life’ applications.
