In modern polymer processing and flexible PVC compounding, shifting toward robust raw materials with superior stability under harsh environments is essential. Plasticizer DPHP (Bis(2-propylheptyl) phthalate) stands out as a premier branched high-molecular-weight plasticizer. Chemically defined under CAS No. 53306-54-0, DPHP acts as an optimized substitute for lower phthalates like DINP and DIDP. Because of its heavier molecular chain structure, it minimizes evaporation losses during processing and service, ensuring excellent low-temperature flexibility and elite structural retention for long-life industrial products.

Why Choose Our DPHP Plasticizer?
- ✓ Extreme Low Volatility: The high molecular structure significantly lowers weight loss during dry-blending and high-temperature extrusion, keeping plasticizer mist low inside your manufacturing facility.
- ✓ Superior Weathering & UV Resistance: DPHP demonstrates an inherently strong resistance against solar degradation and oxidative embrittlement, keeping flexible PVC from cracking outdoors.
- ✓ Excellent Fogging & Migration Performance: Its molecular layout lowers plasticizer migration into adjacent layers and suppresses vehicle window fogging, making it highly preferred for modern transportation substrates.
Primary Applications
DPHP is widely used to formulate premium-grade flexible vinyl sheets, plastisols, and technical synthetic elastomers:
Automotive & Wire Engineering
Extensively selected for high-temperature electrical wire cables, protective harnesses, automotive underbody coatings, and soft interior vinyl dashboards.
Outdoor Construction & Roofing
An industry standard for heavy-duty swimming pool liners, weather-resistant PVC roofing membranes, tarpaulins, and dynamic architectural coated fabrics.
Industrial Profiles & Hoses
Perfect for creating high-flexibility vinyl window gaskets, weatherstripping profiles, agricultural spray hoses, and robust conveyor belt top coats.
Quality Assurance & Global Compliance
As a leading international supplier, we understand that substance purity, molecular consistency, and strict regulatory tracking directly safeguard your production lines. Our advanced chemical refineries operate under strict control standards to ensure stable international integration:
- Advanced Analytical Quality Control: Every delivery batch of our DPHP plasticizer liquid undergoes strict gas chromatography-mass spectrometry (GC-MS) verification, acid value titration, and refractive index checking to maintain consistent batch metrics.
- Comprehensive Regulatory Alignment: We maintain up-to-date tracking structures across continents. Our DPHP comes with fully integrated multilingual GHS Safety Data Sheets (SDS), technical datasheets, and regulatory confirmations fully matching EU REACH guidelines and regional criteria.
- Flexible Logistics Infrastructure: We provide diverse logistics delivery choices, including stainless steel ISO tank containers, intermediate bulk containers (IBC drums, 1000kg), and standard steel drums (200kg) packed under dry nitrogen padding to prevent moisture intake.
⚠ Storage & Handling Guidelines
Maintaining appropriate climate controls is necessary to safeguard the long-term chemical purity of Plasticizer DPHP liquid. While naturally stable, improper moisture or temperature exposure can cause a slow trace rise in acidity.
- • Warehouse Environment: Store the chemical containers in a cool, dry, and well-ventilated space. Keep storage zones separated from strong oxidizers, open spark risks, and high-heat processing equipment.
- • Moisture Protection: Phthalate liquids can absorb trace ambient humidity. Keep bung caps and container seals securely closed when not actively dispensing liquid to avoid atmospheric water absorption.
- • Inventory Shelf Life: Under appropriate sealed warehouse storage, our premium DPHP carries a certified shelf life of 24 months from the date of manufacture. Utilizing a strict First-In, First-Out (FIFO) warehouse workflow is strongly recommended.
