Plasticizer DPHP 500ml Sample

DPHP stands for Di(2-propylheptyl) Phthalate, a high-molecular-weight phthalate plasticizer developed as a modern replacement for DOP and DINP in demanding applications. It’s widely used in Europe and other regions because it combines excellent permanence, low volatility, and good mechanical performance with better regulatory acceptance compared to lower-molecular-weight phthalates.

Here’s a structured overview of Plasticizer DPHP:

Full Name: Di(2-propylheptyl) Phthalate

Molecular Formula: C₂₈H₄₆O₄

Appearance: Clear, colorless to slightly yellow, oily liquid

Key Features

High molecular weight → very low volatility and migration

Excellent weatherability and aging resistance

Provides long service life in PVC products (durable in heat and outdoor conditions)

Good balance of flexibility, mechanical properties, and plasticizing efficiency

Performs better than DINP/DOP in high-temperature and long-term use

Applications

Construction materials: PVC profiles, pipes, roofing membranes

Automotive interiors and exterior parts requiring heat and UV resistance

Cables and wires with demanding durability requirements

Flooring, wall coverings, and synthetic leather

Used in high-performance flexible PVC where longevity is crucial
