  • Applications

    Cyclohexyl 2-ethylhexyl phthalate (CAS 1169-98-8) is primarily used as a plasticizer for PVC and other polymers to improve flexibility and low-temperature performance. It is also employed as a plasticizer in coatings, paints and varnishes; in adhesives and sealants to enhance flexibility; in flexible films and packaging materials to impart extensibility and seal properties; and as a processing aid or intermediate in polymer formulation and manufacturing.
