Acrylonitrile- Butadiene-Styrene (ABS) is a rubber toughened ther-moplastic, characterized by its notch insensitivity and low cost. On the other hand, the ABS limitations are: poor flame and chemical resistance, and low thermal stability [1]. The commercialization of PC began in 1958; the pro-duction of the PC/ABS blends started on 1977.
