Diundecyl Phthalate (DUP) is a linear phthalate ester plasticizer which is produced from a mostly linear C11 alcohol. Due to its excellent high temperature properties, DUP is a good choice when high temperature stability is required. DUP boasts strong outdoor weathering capabilities and good low temperature flexibility properties, making it a prime plasticizer for long-life outdoor products such as vinyl coated fabrics. DUP’s low fogging characteristics make it useful for car interior plastic parts. Other applications for DUP include films, vinyl rooming membranes, automotive wire harnesses, and electrical wire insulation.
