Extreme pressure additives increasingly important in metalworking fluids

Extreme pressure (EP) additives react with metal surfaces to form a solid protective layer and reduce friction in severe metalworking conditions. EP additives can include soap esters, polymeric esters, chlorinated paraffins, organo phosphorus and sulphur. Thermally activated, the primary distinction between chemistries is their different activation temperatures as metalworking fluids (MWF) can be exposed to […]
