Di-2-propylheptyl phthalate

Di-2-propylheptyl phthalate (CAS 53306-54-0), commonly abbreviated as DPHP, is a high-molecular-weight phthalate plasticizer used primarily in PVC compounding.

It functions as a primary plasticizer, imparting flexibility and processability to rigid polymer systems across demanding industrial applications. In PVC formulations, DPHP delivers low volatility and strong permanence.

This makes it a preferred choice for wire and cable insulation where long-term performance under elevated temperatures is required. Flooring materials and roofing membranes rely on DPHP-plasticized PVC for durability.

Wall coverings in the building and construction sector also benefit from its dimensional stability. Rubber compounders use it to improve flexibility in seals, gaskets, and technical profiles where resistance to migration is critical.

Its high boiling point also suits it for automotive interior components and industrial sheeting. These materials must maintain flexibility across a broad service temperature range to ensure long-term structural integrity.

Di-2-propylheptyl phthalate is supplied as a clear, low-viscosity liquid in bulk quantities, including ISO tank, drum, and IBC formats. It is available in technical grade for industrial PVC and rubber processing.

Purity levels typically meet or exceed 99%, with product conforming to established industrial plasticizer specifications. This ensures consistent performance and reliability for large-scale manufacturing requirements.
