Product Description

This product is formulated using custom-synthesized esters, combined with a blend of premium additives—including extreme-pressure, anti-wear, antioxidant, rust-inhibiting, and anti-corrosion agents—crafted through advanced manufacturing processes. It is safe, non-toxic, biodegradable, and environmentally friendly.

Product Performance

Excellent flame retardancy, safe and reliable, reducing fire risks;

Excellent lubricity effectively reduces equipment wear and minimizes kinetic energy loss during transmission.

Its excellent viscosity-temperature characteristics ensure superior lubrication and fluidity even under demanding operating conditions.

Excellent wear resistance, corrosion and rust prevention, and oxidation stability—these properties help slow down equipment wear and extend its service life.

Technical Specifications

SH/T 6045-2021

Scope of Application

Suitable for hydraulic systems in industries such as steel, metallurgy, coal mining, machinery manufacturing, and chemical processing—particularly those operating in environments with open flames or high temperatures. Examples include hydraulic systems used in equipment like coke oven doors, die-casting continuous casting machines, electric furnaces, high-speed wire rolling mills, and hot-rolled coil machines in the steel industry.

Instructions for Use and Precautions

According to equipment lubrication guidelines, select oil products with appropriate viscosity. During use and storage/transportation, prevent contamination by foreign objects and strictly avoid mixing in mechanical impurities or water. Ensure the oil tank remains clean—when changing the oil, thoroughly flush both the tank and oil lines—and never mix it with oils of different types.
