Ergoplast SDO plasticiser is a clear, colourless organic liquid, insoluble in water, used in the processing of plastics, in particular PVC and copolymers thereof. Can also be used as an admixture to other plasticisers such as dioctyl terephthalate.

Ergoplast SDO is the primary plasticiser giving the PVC products very good resistance to low temperatures. In mixtures, PVC has high plasticising capacity, low volatility, and good dielectric properties. Ergoplast SDO can also be used in the processing of rubber and as an additive for lubricating oils and greases.
