  • Applications

    Bis(2-(2-(2-butoxyethoxy)ethoxy)ethyl) succinate (CAS 65520-45-8) is a diester of succinic acid bearing a polyether-containing diol arm with a 2-butoxyethoxy group. In practical industrial use, it is commonly evaluated as a plasticizer for polymers and polyesters to improve flexibility and processability; it may also function as a solvent or co-solvent in coatings, inks, and related formulations to enhance flow and component dispersion. Its polyether character makes it suitable as a compatibilizer or processing aid in polymer blends and in coating or adhesive formulations. It can be employed as a processing solvent in cleaning or surface-treatment products where polar and semi-polar components need dissolution. Depending on local regulations, it may be used as an intermediate or additive for the preparation of polyether- or polyester-based materials.
