Trimethylolpropane trioleate

Trimethylolpropane trioleate (CAS 57675-44-2 ), also marketed as Nissan Unister H-381, is a synthetic ester derived from trimethylolpropane and oleic acid. It functions as a base fluid and lubricity additive in high-performance lubricant formulations. This chemical offers strong oxidative stability and low-temperature fluidity that are critical for demanding industrial and automotive applications. In fully synthetic and semi-synthetic lubricants, it serves as a base oil component for compressor oils. It is frequently utilized in gear oils and hydraulic fluids where extended service intervals are required. Metalworking fluid formulators incorporate it to improve lubricity in cutting and forming operations, reducing tool wear in precision machining. The product is also used as a plasticizer in specialty polymer and rubber compounding where compatibility with oleate-based systems is a formulation requirement. In the energy sector, it appears in turbine and circulating oil formulations. These formulations are specifically designed to meet demanding thermal and oxidative stability specifications. Trimethylolpropane trioleate is supplied as a clear to pale yellow viscous liquid for various industrial uses. It is available in technical and lubricant grades, with packaging typically ranging from drums to intermediate bulk containers (IBCs) for industrial supply volumes. Specifications are generally aligned with technical-grade purity standards. These standards are appropriate for lubricant and industrial fluid applications across the global manufacturing sector. The material ensures consistent performance in high-pressure environments and specialized chemical processing tasks. Contact us for supply of Trimethylolpropane trioleate Request Quote
