Import 2, 5-Di (T-Nonyldithio) - 1, 3, 4-Thiadiazole — Buy in Bulk from Supplier in China

Yantai Heng Nuo Chemical Technology Co., Ltd supplies 2,5-di(t-nonyldithio)-1,3,4-thiadiazole, a metal deactivator and extreme pressure anti-wear agent for lubricant formulations. The product, also known as TH-571 or by trade names like Amoco 158, is a yellow-brown transparent liquid with a measured sulfur content of 31.0%. It is manufactured through a complex oxidative coupling reaction, introducing active S and N heteroatoms into a macromolecular chain to provide superior performance compared to older thiadiazole derivatives like T561.

As a modified thiadiazole derivative, TH-571 offers improved oil solubility and the ability to form a complete, corrosion-inhibiting protective film on non-ferrous metal surfaces, particularly copper. Its key functional properties include metal deactivation, extreme pressure protection, anti-wear capability, oxidation resistance, and the ability to suppress the catalytic activity of metal ions in oil. The product has an acid value of 10 mgKOH/g and a moisture content of 0.005%, meeting strict quality controls for sensitive applications.

This additive is used in the formulation of automotive engine oils, gear oils, metalworking fluids, anti-wear hydraulic oils, and steam turbine oils. It is sourced by lubricant blenders and additive package manufacturers who require a low-dosage, high-performance component to protect machinery from corrosion and wear. Yantai Heng Nuo packages the product in 30L and 200L barrels, with a sealed shelf life of 12 months at room temperature.
