Abstract
A flame retardant grease composition is described for low temperature applications comprising mixed alkoxy and alkylated phenyl triesters of a phosphorus oxyacid as a base fluid and a siliceous microparticulate inorganic thickener. The grease has excellent low, medium and high temperature physical properties, which makes it suitable for service in applications with wide temperature (-40.degree. C. to +150.degree. C.) fluctuations. The benefits of reduced rolling resistance can be realized in significant energy savings and the possibility of constructing longer conveyor lines with existing drive motors.
