Application
Diisodecyl Phthalate (DIDP) is a high-molecular-weight, general-purpose plasticizer widely used in flexible PVC products. It offers excellent permanence, high-temperature performance, and low-temperature flexibility, making it particularly suitable for demanding applications such as wire and cable insulation (DIDP-E), automotive interior trim, roofing membranes, and tarpaulins. DIDP enhances electrical resistivity in certain PVC compounds, improving insulation properties, and is favored in products requiring low fogging and long-term durability under outdoor exposure. As one of the highest-volume general-purpose plasticizers in its class, DIDP is also recognized for its safety, as it is not classified as carcinogenic, mutagenic, or toxic to reproduction, and does not meet criteria for endocrine disruption.
Grades Available
Non-Inhibited ("Normal", "DIDP-N"); Inhibited ("Electrical", "DIDP-E").
