Pentaerythritol Oleate (PETO)
High-performance synthetic ester with superior extreme pressure and anti-wear properties, delivering powerful lubrication protection for heavy-duty applications.
Product Overview
ARNOCO Pentaerythritol Oleate (PETO) is a high-performance synthetic ester base oil produced by the esterification of pentaerythritol and oleic acid. It features exceptional extreme pressure and anti-wear properties, excellent thermal stability, and strong adhesion. PETO is an ideal base oil or additive for heavy-duty lubricants, metalworking fluids, and greases.
Widely used in gear oils, hydraulic fluids, cutting fluids, drawing oils, and greases. Ideally suited for demanding conditions such as high loads, elevated temperatures, and boundary lubrication.
Core Advantages
Excellent extreme pressure performance
Excellent extreme pressure and anti-wear performance, maintaining effective lubrication protection even under high-load conditions.
Excellent thermal stability
Resists thermal decomposition and oxidation at high temperatures, minimizes carbon buildup, keeps equipment clean, and extends maintenance intervals.
Strong Adhesion
Strong adhesion to metal surfaces, long-lasting oil film, reduces lubricant loss and replenishment frequency
