Tech Data

Polymerized High Viscosity Branched-Chain Fatty Ester

Focus Ester PA 2500 is a synthetic polymerized ester designed to boost performance and enhance finish in severe metalworking applications. It is a high molecular weight ester designed to offer the highest lubricity available and it has a molecular weight that gives it a perfect structure to replace chlorinated paraffins. Focus Ester PA 2500 is a fully saturated branched-chain fatty acid, which offers the highest level of hydrolytic, oxidative and biostability properties. In addition to replacing chlorine, Focus Ester PA 2500 can be used to replace or reduce treat levels of all other EP additives, like phosphorous, inactive sulfur, active sulfur, lard oil, blow oil and other fatty friction modifiers.


Focus Ester PA 2500 is formulated into emulsion systems like soluble oils, semi-synthetic, synthetic, drawing and stamping and other water-dilutable fluids to provide exceptional lubricity. Treatment levels of 1% to 15% into the concentrate are suggested. Focus Ester PA 2500 can be used in straight cutting oil and industrial lubricant oil applications in combination with or without low amounts of active sulfur and phosphorus, depending upon the severity of the operation. Focus Ester PA 2500 can replace or reduce the amount of chlorine, sulfur, blow oil, lard oil and other fatty friction modifiers.
