  • Applications

    Diisononyl phthalate (CAS 28553-12-0) is a widely used plasticizer for flexible PVC and related polymers, providing softening and processability; typical applications include flexible PVC flooring and decorative vinyl substrates (wall coverings, films); electrical cable insulation and other PVC components; automotive interiors and consumer furniture containing PVC; coatings and inks for flexible substrates; adhesives and sealants formulated with DINP; and elastomeric or soft polymer systems requiring high plasticization.
