High Temperature Grease: RPL-HT600

Product Description:

Davley Darmex RPLHT600 is 100% synthetic high temperature EP grease with an inorganic thickener for use at sustained operating temperatures above 200C (400F). It is formulated using a high viscosity stable synthetic ester fluid thickened with an inorganic gel. The synthetic ester fluid has superior oxidation and thermal stability providing extended lubrication intervals at high temperatures without deteriorating into hard, abrasive or sludge-like residues. 

RPL-HT600 contains PTFE solid lubricant, a thermoplastic fluoropolymer having non-stick properties and an extremely low coefficient of friction thus helping to lower power consumption. The reduced maintenance and long lubrication life provided will reduce overall lubrication costs making it extremely cost effective.

Typical applications include a wide range of high temperature uses including fan and blower bearings, furnace door hinges, bakery, paint, kiln oven conveyor bearings, chains, tender frame ovens and other extreme temperature applications.

Note: RPL-HT600 is not compatible with other greases. Purge or clean old grease thoroughly before using.
