Pentaerythritol tetraoleate is widely used as a lubricant additive in various industrial applications. It enhances the performance of lubricants by reducing friction and wear between moving parts, which is particularly beneficial in high-pressure and high-temperature environments. The compound is also utilized in the formulation of metalworking fluids, where it helps improve the efficiency of cutting, grinding, and stamping processes by providing excellent lubrication and cooling properties.

In the plastics industry, it acts as a plasticizer and stabilizer, improving the flexibility and durability of plastic products. Additionally, it finds application in the production of synthetic esters, which are used as base oils in biodegradable lubricants and greases. Its oleochemical nature makes it suitable for environmentally friendly formulations, aligning with the growing demand for sustainable and eco-friendly products.
