IDE commercial use has proved that Dibutyl Sebacate materially aids processors t o adapt natural and synthetic elastomers t o industrial ap plications. This plasticizer is especially valuable in compounding elastomers for applications where the finished product must have low-temperature flexibility. A typical use is i n equipment for high flying bombing and fighting planes where extreme cold is encountered. As produced b y The Resinous Prod ucts & Chemical Company, Dibutyl Se bacate, is eminently workable in the rubber factory. Its purity, water-white color and uniform high quality guaran tee users unvarying results from one production run t o the next.
