Trimethylolpropane trioleate is a synthetic ester base oil with excellent lubricating properties, high viscosity index, and good fire resistance. It boasts a biodegradation rate of over 90%, making it an ideal base oil for No. 46 and 68 synthetic ester-type fire-resistant hydraulic fluids. As an oiliness agent, it is widely used in cold-rolling fluids for steel plates, tube drawing oils, cutting oils, release agents, and other metalworking fluids. It can also serve as an intermediate for textile and leather auxiliaries and as a textile oil.
