Used primarily as a plasticizer in various polymers, including PVC resins and cellulose-based plastics such as cellulose acetate and cellulose nitrate, to improve flexibility, workability, low-temperature performance, and transparency. It maintains plasticity in cold environments and is commonly found in films, coated surfaces, plastic sheets, wire insulation, coatings, sealants, adhesives, printing inks, and as a component in synthetic lubricants. Valued for its good solvating properties, compatibility with various resin systems and additives, ability to reduce melting points of formulations, and high film stability. Its relatively low volatility makes it suitable for applications requiring prolonged performance under moderate heat.
