Bis(2-propylheptyl) Phthalate DPHP

Product Overview

Bis(2-propylheptyl) Phthalate (commonly called DPHP) — chemical name Bis(2-propylheptyl) phthalate, CAS 53306-54-0 — is a high-performance phthalate-type plasticizer formulated for demanding PVC applications. DPHP combines excellent thermal stability, low volatility and superior weather resistance, making it well suited for outdoor PVC, wire & cable insulation (including 90°C compound formulations), automotive interiors and synthetic leather.

Performance & Benefits

Low volatility & minimal migration: DPHP shows lower volatility than DIDP and DINP alternatives, reducing plasticizer loss and fogging in automotive interiors.
Excellent heat-aging resistance: suitable for cable compounds rated to 90°C and high-temperature applications.
Superior weatherability / UV stability: extends service life of outdoor PVC products (pool liners, tarpaulins, awnings).
Good electrical insulation: comparable to DIDP for wiring and cable insulation.
Low fogging (low-fog): favored by automotive leather manufacturers for interior trim and seating.

Typical Applications

1. Wire & cable insulation and jacketing (90°C cable compounds; can replace DIDP).
2. Automotive interior components (trim, synthetic leather, dashboards) due to low fogging.
3. Outdoor PVC products (pool liners, tarpaulins, awnings) requiring long weather life.
4. Synthetic leather & coated fabrics to improve appearance and reduce volatilization.
5. Specialty polymer formulations where lower specific gravity and improved performance vs DINP are desired.
