  • Applications

    Tetraethylene glycol di(2-ethylhexanoate) (CAS 18268-70-7) is used primarily as a high-boiling plasticizer for PVC and other polymers, improving flexibility and processability; it also serves as a solvent or co-solvent for coatings, inks, and adhesives due to its polarity and compatibility with polyols and resins; as a processing aid in polymer manufacturing it can assist resin dissolution and viscosity control; it can function as a lubricant or lubricant additive in industrial lubricants and metalworking fluids; and it may act as a nonionic surfactant or emulsifier in coatings and cleaners because of its polyether backbone.
