Di(2-propylheptyl) Phthalate (DPHP)
CAS: 53306-54-0
Chemical Formula: C₂₈H₄₆O₄
Molecular Weight: 446.6624
DPHP is a premium high-performance primary plasticizer widely utilized as a core additive in the mass manufacturing of polyvinyl chloride (PVC) plastic products. Engineered with an advanced molecular structure, this plasticizer significantly enhances the inherent flexibility, tensile extensibility, and softness of PVC resin base materials while strengthening structural stability and long-term service durability.
- Superior Thermal Stability: Outstanding heat resistance for long-term high-temperature PVC service
- Ultra-Low Volatility: Minimal weight loss and anti-fogging performance for automotive interior parts
- Premium Insulation: High volume resistivity to meet strict wire & cable electrical standards
- Low Migration Performance: Prevents additive bleed-out and extends product service life
- Wide Polymer Compatibility: Perfect miscibility with PVC, rubber, coating resins and DOP/DINP blends
- Excellent Weather Resistance: Stable UV performance for outdoor films and waterproof cloth
- Efficient Plasticization: Powerful softening capacity with low addition dosage
- Anti-Leaching Property: Strong resistance to water and soap liquid extraction
Application Guide: Mainly used in the production of wires and cables, automotive interiors, artificial leather, waterproof oilcloth, automotive chassis sealing materials, coil coatings, advertising films, and related applications.
