Product Description
Dioctyl Adipate (DOA) is a widely-used cold-resistant plasticizer. At room temperature, it presents as a colorless to pale-yellow transparent oily liquid with a faint odor. Its exceptionally low melting point greatly enhances low-temperature softness, enabling end-products to retain outstanding flexibility and ductility under cold-condition environments. DOA serves as a critical additive for formulating cold-resistant end-products.
