Professional R&D and excellent quality plasticizer chemicals

DOA (Dioctyl Adipate) is a non-phthalate, highly efficient plasticizer designed to give excellent low temperature properties to polyvinyl chloride (PVC). Its excellent wetting characteristics make it desirable for plastisol use where low plasticizer content coupled with low viscosity, as well as good fusion characteristics are necessary. DOA is

Dioctyl adipate DOA plasticizer (Bis (2-Ethylhexyl) Adipate) is a light colored, oily liquid generally used as a plasticizer for PVC. It can be used alone or blended with other plasticizers. In PVC, DOA features flexibility at low temperatures, good electrical properties, good resistance to weathering, and good stability to heat.

NOAEL of DEHP compared with some alternative plasticizers. The critical endpoint is shown to indicate that for some of the chemicals it is different from reproductive effects.

TI/N-CPN/IP Plastomoll DOA / June 2025 Page 3 of 4 Plastomoll DOA Description Plastomoll DOA is a highly efficient plasticizer which imparts excellent low temperature flexibility and resistance to impact to the base resin. For these reasons it finds wide use in polymeric systems based on vinyl, nitrocellulose and rubber.

Extenders are a subset of secondary plasticizers. They are commonly employed with primary plasticizers to reduce costs in general purpose flexible PVC. They are mostly low cost oils having limited compatibility in PVC. They are added to reduce cost and in some cases to improve fire resistance.
