Dioctyl Phthalate (DOP) & Dibutyl Phthalate (DBP)
Plasticizers such as DOP and DBP are widely used to enhance flexibility, softness, and workability of plastics, especially PVC. They improve processing efficiency and durability. With good compatibility and stability, these plasticizers ensure consistent performance in cables, films, flooring, and other polymer applications.
Description
DOP & DBP Plasticizer Supplier — High-Quality PVC Additives for Flexible Film, Cable & Footwear Industries
Plasticizers are the single largest category of polymer additives by volume, and within this segment, dioctyl phthalate (DOP) and dibutyl phthalate (DBP) remain the workhorse plasticizers that define the performance envelope of flexible PVC products worldwide. These phthalate esters function by intercalating between PVC polymer chains, reducing intermolecular forces and imparting flexibility, elongation, and low-temperature performance that rigid PVC cannot achieve. For procurement managers in the wire and cable, footwear, films, and flooring industries, the quality of the plasticizer directly governs the end-product’s migration resistance, volatility, and long-term flexibility retention. Davar ChemTech supplies both DOP and DBP in industrial-grade purity, sourced from ISO-certified esterification plants with full traceability from 2-ethylhexanol and phthalic anhydride feedstock through to finished product. Every batch is accompanied by test certificates covering ester content, acid number, color (Pt-Co), and moisture content.
Key Technical Features

- DBP offering excellent compatibility with nitrocellulose, cellulose acetate, and synthetic rubbers beyond PVC
- Low volatility grades ensuring minimal plasticizer loss during prolonged service at elevated temperatures
- Good UV stability for outdoor PVC applications such as tarpaulins and greenhouse films
- Compatible with primary and secondary stabilizer systems used in PVC compounding
- Available in 200L MS drums and IBC totes for flexible order quantities and safe handling
Industrial Applications
| Industry | Reason for Use |
| PVC Pipes & Fittings | Imparts flexibility, impact resistance, and processing ease to rigid PVC formulations for plumbing and irrigation |
| Wire & Cable | Provides insulation flexibility and thermal stability for building wire, power cables, and automotive wiring harnesses |
| Footwear Manufacturing | Used in PVC soles, straps, and synthetic leather to achieve required softness and flex endurance |
| Films & Sheets | Enables production of flexible packaging films, stationery folders, and inflatable products with consistent gauge |
The PVC industry consumes approximately 80% of global phthalate plasticizer production, and for good reason — the performance-to-cost ratio of DOP in flexible PVC remains unmatched by alternative chemistries. In wire and cable insulation, DOP plasticized PVC must meet stringent IEC standards for heat deformation, volume resistivity, and thermal aging retention. The plasticizer’s migration resistance is critical here; premature loss of plasticizer causes insulation hardening and eventual electrical failure. DOP’s relatively high molecular weight and low volatility make it the preferred choice for power cable insulation where service temperatures can reach 70–85 °C continuously. In the footwear sector, plasticizer selection directly influences sole flexibility, abrasion resistance, and low-temperature cracking behavior — DBP is often preferred here due to its faster gelation rate in PVC plastisols and its ability to produce softer compounds at lower addition levels. The flexible films and sheets segment relies on DOP for its balanced processing window, good clarity in thin-gauge films, and compatibility with a wide range of PVC resin grades.

Storage, Handling & Safety
Both DOP and DBP require careful handling under standard chemical safety protocols. Use chemical-resistant gloves (nitrile recommended), safety goggles, and adequate ventilation when handling open containers. Avoid prolonged skin contact and inhalation of vapors. Store in tightly sealed original containers in a cool, dry, well-ventilated area away from heat sources and open flames. DOP and DBP are classified as marine pollutants under IMDG — proper shipping documentation and container labeling are mandatory. In case of spills, contain with inert absorbent material and dispose of as hazardous waste per local regulations.
Supply Capability & Distribution Strength
Davar ChemTech’s Vadodara location provides direct highway access to India’s largest PVC consuming clusters — including the cable belt in Hyderabad, the footwear hub in Agra and Kanpur, and the pipe and fittings corridor in Gujarat and Rajasthan. Our liquid chemical logistics capability includes dedicated tank-truck arrangements for high-volume buyers, as well as standard drum shipments for smaller requirements. We typically maintain ready stock of both DOP and DBP, enabling dispatch within 48 hours of order confirmation. Custom blending and alternative plasticizer grades (such as DINP, DOTP, and DOA) can be arranged on request for specialty applications.
