📝 Product Overview

Dioctyl Adipate (commonly known as DOA or Bis(2-ethylhexyl) adipate) is a high-performance cold-resistant plasticizer for Polyvinyl Chloride (PVC) and other resins. It has the CAS number 103-23-1 and chemical formula ${}_{\mathrm{}}{}_{\mathrm{}}{}_{\mathrm{}}$.

DOA is characterized by its excellent low-temperature flexibility, high plasticizing efficiency, and low viscosity. It is particularly valued in applications requiring high clarity and non-toxicity, making it a preferred choice for food-grade materials and products exposed to cold environments.

🚀 Application Areas

① DOA is widely utilized in sectors where softness, cold resistance, and food safety are essential.

Food Packaging (Cling Film): DOA is a key plasticizer for food-grade PVC cling films and wraps. Its excellent compatibility and low migration profile ensure that the film remains flexible and transparent while meeting food safety regulations.

 ② Cold-Resistant PVC Products: It is essential for manufacturing soft PVC products intended for winter use or cold storage, such as refrigeration gaskets, agricultural films, and low-temperature cables. It ensures that the material does not become brittle or crack in freezing conditions.

③ PVC Plastisols: Due to its low viscosity, DOA is used to adjust the flow properties of PVC plastisols. It is ideal for dip molding and rotation molding processes where high-speed production and uniform coating are required.

④ Synthetic Leather and Upholstery: Used in high-end synthetic leather for the automotive and furniture industries to provide a permanent soft feel and improved resistance to weathering and aging.

 ⑤Specialty Lubricants and Coatings: DOA also serves as a synthetic base oil or additive in lubricants and high-performance coatings, providing excellent oxidative stability and lubricity.
