Product Description
Dioctyl Adipate (DOA) is the dioctyl ester of adipic acid, a colorless or light yellow transparent oily liquid. Above all, DOA has efficient plasticization and good thermal stability. Also it is used as packaging film for frozen foods, plates, etc. Offered here at Integratechem, one of the leading and professional China manufacturers and suppliers. Furthermore, dioctyl adipate factory produces it use adipic acid and octanol.

Application & Advantages
Dioctyl Adipate (DOA) is a typical cold-resistant plasticizer. This product has high plasticization efficiency when heated, and little color change when heated. It is suitable for various resins such as polyvinyl chloride, vinyl chloride copolymer, polystyrene, and synthetic rubber. So dioctyl Adipate can give products good low-temperature softness and light resistance, and the products have good hand feel. Manufacturers mostly use DOA with main plasticizers such as DOP and DBP for cold-resistant agricultural films, frozen food packaging films. Also it is used for wire and cable coatings, artificial leather, boards, outdoor water pipes, etc.
Packaging / Storage / Transport of Dioctyl Adipate (DOA)
Packing and loading: firstly, factories packed it in 200L iron drum or plastic drum,190 kg for net weight. Secondly, store in a dry and ventilated place indoors and prevent violent impact and rain during transportation. Most importanly, risk of burning in high heat, open flame or contact with oxidants, and keep container tightly closed when not in use. Furthermore, store in an airtight container and keep in a cool, dry, well-ventilated area away from incompatible materials.
