Oleyl polyether phosphate ester PMET PE1650

What is Oleyl polyether phosphate ester PMET PE1650?

PMET PE1650 is a special structure oil-alcohol polyether phosphate ester. It is a type of lubricant, extreme pressure anti-wear additive, corrosion inhibitor, wetting agent, emulsifier, etc. As a long-chain phosphate ester, it can be applied in high-load conditions causing boundary lubrication to reduce friction and wear, extend equipment service life, reduce tool wear and lower energy consumption. Compared with other sulfur-based compounds and chlorine-based compounds, phosphate esters can reduce corrosion, especially having excellent aluminum corrosion inhibition effect.

Features of Oleyl polyether phosphate ester PMET PE1650

Multifunctionality: Integrates lubrication, extreme pressure anti-wear performance, emulsification, rust prevention, aluminum corrosion inhibition, and low-foaming properties, suitable for complex working conditions.

Eco-Friendly & Safe: Biodegradable and non-ecotoxic, complying with environmental regulations.

High Performance:

Excellent emulsification stability for both water-based and oil-based systems.

Outstanding rust prevention after amine neutralization, particularly effective for aluminum and stainless steel machining.

Superior extreme pressure lubrication compared to traditional sulfur/chlorine additives, with lower corrosivity.
