DownloadsDOS / DOA
DOS (CAS 122-62-3) and DOA (CAS 123-79-5) are aliphatic dibasic ester plasticizers that markedly improve flexibility and flexing performance at low temperature, commonly used in -40°C-rated cable compounds, conveyor belts and low-temperature flexible goods, usually combined with a primary plasticizer. The exact ratio should be confirmed through a low-temperature brittleness test.
