Used as a plasticizer in polymer formulations to improve flexibility and durability of plastics, especially in polyvinyl chloride (PVC) and related materials. Enhances low-temperature performance and elongation properties without significantly compromising mechanical strength. Also serves as an intermediate in the synthesis of lubricants, surfactants, and specialty esters due to its bifunctional ether structure. Its hydrophobic nature and stability make it suitable for use in coatings, adhesives, and sealants where moisture resistance and long-term performance are required.
