Dioctyl Adipate (DOA)

Dioctyl Adipate (DOA) is a versatile, colorless or light yellow transparent oily liquid that emits a faint ether-like smell. Known for its excellent plasticization capabilities and thermal stability, DOA is a top choice for plasticizer applications, particularly in the production of flexible plastics and packaging films for frozen foods. With a density of 0.925 g/ml at 20°C, a boiling point of 208–218°C, and a freezing point of -67.8°C, it is widely used for various purposes. Comparing Dioctyl Adipate with other plasticizers, it stands out for its cold resistance and durability.

Dioctyl Adipate Applications & Advantages

DOA is a cold-resistant plasticizer that performs well at low temperatures. So it is widely used in plasticizers for PVC, vinyl chloride copolymer, polystyrene, and synthetic rubber. Additionally, its uses in flexible plastics and other cold-resistant applications make it a preferred choice for products like:

Agricultural Films: Cold-resistant films ideal for outdoor use.
Frozen Food Packaging: Provides flexibility and cold resistance for packaging films.
Wire and Cable Coatings: Enhances flexibility in wire insulation and outdoor water pipes.
Artificial Leather & Boards: Improves material performance, ensuring softness, durability, and resistance to light.

Best Practices for Using Dioctyl Adipate in Manufacturing recommend combining it with primary plasticizers like DOP and Dibutyl Phthalate for enhanced flexibility and performance. Further more, its low-temperature performance makes it ideal for products exposed to extreme weather conditions.

Compare Dioctyl Adipate with Other Plasticizers: When comparing DOA to other plasticizers, such as DOP (Dioctyl Phthalate), DOA stands out for its superior cold resistance and lower toxicity. It offers excellent performance in environments where flexibility and stability at low temperatures are critical, making it a better choice for specific applications like frozen food packaging and agricultural films.

Packaging / Storage / Transport

DOA is packed in 200L iron or plastic drums with a net weight of 190 kg. For safe handling and transport:

Storage: Store in a cool, well-ventilated area away from heat sources.
Safety and Handling of Dioctyl Adipate: Avoid contact with strong oxidizers and heat. Ensure proper sealing of containers to prevent contamination.
