Abstract
A metal forming lubricant suitable for extreme condition use is formulated to contain one or more differential solid lubricants composed of a high melt temperature, substantially halogen-free thermoplastic in addition to conventional lubricants such as organic phosphate esters and natural and synthetic polymer waxes. The lubricants offer superior performance while resisting the tendency to foul metal working dies with gummy deposits.
