What is 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.
Where is Di-2-propylheptyl phthalate used?
- PVC compounding: primary plasticizer imparting flexibility and processability to rigid polymer systems
- Wire and cable insulation: low volatility and strong permanence for long-term performance under elevated temperatures
- Flooring materials and roofing membranes: durability
- Building and construction: wall coverings with dimensional stability
- Rubber compounds: flexibility in seals, gaskets and technical profiles with resistance to migration
- Automotive interior components and industrial sheeting benefit from its high boiling point.
Commercial specifications
- Purity typically 99% or higher
- Conforms to established industrial plasticizer specifications
- Bulk quantities: ISO tank, drum and IBC formats
