Abstract
If you Google “ABS”, you’ll likely get “anti lock brakes” or a reference to stomach muscles. ABS is also the acronym for Acrylonitrile Butadiene Styrene, the most popular engineering polymer - an engineering polymer is one that is used because of its mechanical properties. You have undoubtedly pounded on this material since one of its many applications is for computer keyboards. ABS plastic is an amorphous (lacks the long range order associated with crystals) thermoplastic (one that can repeatedly re-melted) with a glass transition temperature (when it gets significantly softer) of 105 °C and, thus, is easy to manufacture into products by extrusion or injection molding at relatively low temperatures of 204–238 °C. It is also easy to machine.
