Product Description of Dioctyl Adipate CAS#123-79-5
Dioctyl Adipate (DOA) is a widely used plasticizer valued for its excellent low-temperature flexibility. It is typically a clear, colorless to slightly yellow oily liquid with a mild odor at room temperature.
With its low melting point and outstanding cold resistance, DOA helps maintain the softness, flexibility, and durability of materials in low-temperature environments. It is particularly suitable for applications requiring reliable cold-weather performance.
