Dioctyl adipate (DOA), also known as bis(2-ethylhexyl) adipate, is a high-performance ester plasticizer derived from adipic acid and 2-ethylhexanol, with the molecular formula C₂₂H₄₂O₄ and CAS number 103-23-1. It appears as a clear, colorless liquid with a faint odor, characterized by low volatility, good thermal stability, and excellent compatibility with PVC and other polymers.
 

Core Properties

• Exceptional low-temperature flexibility: Maintains polymer pliability at sub-zero temperatures, critical for cold-environment applications.

• High plasticizing efficiency: Reduces polymer melt viscosity and glass transition temperature, improving processability.

• Good compatibility: Works well with PVC, polystyrene, synthetic rubbers, and cellulose derivatives.

• Low volatility & migration: Minimizes property loss over time, suitable for durable and food-contact applications.

• Non-phthalate & low toxicity.

Key Applications

1. PVC products: Cold-resistant agricultural films, cable insulation, hoses, artificial leather, and outdoor pipes.

2. Wire & cable: Enhances electrical insulation and cold-crack resistance.

3. Automotive: Interior materials, seals, and components requiring low-temperature durability.

4. Food packaging: Approved for flexible PVC films (e.g., cling wrap) for frozen/refrigerated goods.

5. Adhesives/coatings: Improves elasticity, spreadability, and cold resistance in sealants and surface coatings.

6. Rubber & elastomers: Acts as a softener for synthetic rubbers in cold-environment seals and parts.

Advantages vs. Traditional Plasticizers

• Outperforms phthalate plasticizers in low-temperature performance and environmental safety.

• Balances flexibility, stability, and processability better than many cold-resistant alternatives.

• Meets strict regulatory standards for sensitive applications like food contact and medical devices.
