Used primarily as a plasticizer in polymer formulations to enhance flexibility and workability of plastics. Improves low-temperature performance and elongation properties in polyvinyl chloride (PVC) and related synthetic materials. Also functions as a lubricant additive, providing thermal stability and reducing friction in industrial applications. Employed in coatings and adhesives to improve film formation and adhesion to substrates. Its long alkyl chains contribute to water resistance, making it suitable for use in sealants and moisture-resistant materials.
