  • Applications

    Di(2-ethylhexyl) phthalate (CAS 117-81-7) is a widely used plasticizer for PVC and other flexible polymers, imparting flexibility and processability to formulations. Typical applications include softening PVC for construction materials, tubing, and wire insulation; a plasticizer in coatings and inks on films and flexible substrates; a component in adhesives and sealants to improve adhesion and flexibility; used in electronics to enhance the elasticity of cable insulation and housings; and in automotive interiors, flexible vinyl components, as well as vinyl flooring and related household vinyl products.
