Import Extreme Pressure And Antiwear Additive Thx-512b — Buy in Bulk from Supplier in China

Extreme Pressure And Antiwear Additive Thx-512b is a thiadiazole-based chemical compound with CAS number 72676-55-2, supplied as a yellow powder. Its nitrogen content ranges from 17.5% to 19.7% and sulfur content from 63.0% to 67.0%, as determined by elemental analysis. The material passes 99% of screening tests at 200 mesh and has an ash content of 0.4%, indicating high purity. It is insoluble in water and benzene, with a melting point between 153°C and 160°C, and a density of 2.09 Mg/m³ at 25°C.

This additive is designed for use in ester-based lubricating oils where extreme pressure and antiwear performance are critical. It functions as a friction modifier and film-forming agent under high load conditions, commonly used in industrial gear oils and hydraulic fluids. The typical industry standard for such thiadiazole derivatives includes nitrogen content between 17% and 20% and sulfur content between 60% and 68%, making this product fall within standard performance ranges. Drying weight loss at 60 - 65°C over two hours is 0.40%, confirming low moisture absorption.

Buyers in the lubricant manufacturing sector, particularly in Asia and Europe, use this additive to enhance the load-carrying capacity of synthetic oils without compromising thermal stability. It is packed in 25kg drums with sealed polyethylene liners and has a shelf life of one year when stored at room temperature in dry conditions. Trade terms are typically FOB Yantai Port, with bulk orders accepted. Buyers should confirm compatibility with base oils and request batch-specific test reports for nitrogen and sulfur content before use.
