Product Description

About DPHP(Di(2-propylheptyl) phthalate)

DPHP, or Di(2-propylheptyl) phthalate, is a high-performance phthalate plasticizer designed to offer excellent durability, low volatility, and enhanced thermal and UV stability.

As a branched-chain phthalate, DPHP provides superior long-term aging resistance, making it particularly suitable for demanding applications that require extended service life and resistance to environmental exposure.

DPHP appears as a clear, colorless, and oily liquid with low odor.
It exhibits excellent compatibility with PVC and other polymers, offering a good balance of plasticizing efficiency and mechanical properties.

DPHP VS DINP

DPHP	DINP
Higher Plasticizing Efficiency with superior long-term performance	Moderate efficiency, stable for general-purpose use
Superior thermal stability, suitable for high-temperature applications	Good thermal stability
Excellent long-term Aging Resistance	Good aging resistance, but lower than DPHP
Better UV and Weather Resistance	Decent UV resistance, less than DPHP
