Description
Bis(2-propylheptyl) phthalate, commonly known as DPHP and sold under trade names including Hexamoll DPHP and Palatinol 10P, is a high-molecular-weight phthalate plasticizer with CAS number 53306-54-0. It carries no assigned E-code and is identified under EC number 258-469-4.
DPHP is used primarily in PVC compounding for wire and cable insulation, automotive interior components, and flexible flooring, where its branched C10 alcohol structure reduces polymer chain interactions to deliver flexibility at elevated temperatures. Its low volatility makes it suitable for applications requiring long-term dimensional stability under thermal stress.
DPHP is supplied as a clear oil and is subject to REACH registration requirements within the European Union. Procurement teams should verify current SVHC status and regional regulatory compliance before specification. Standard packaging formats include drums and IBC containers, with bulk quantities available depending on supplier agreements.
