Heat Resistant (High Heat) ABS
Heat resistant ABS is a grade of ABS. It has the second highest strength and second lowest ductility compared to the other variants of ABS. The graph bars on the material properties cards below compare heat resistant ABS to: styrenic plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
