Notes:
The balance of engineering properties of rubber-modified polystyrene make it attractive for many applications, but it is difficult for the design engineer to relate laboratory data to service requirements because of differences in strain rates, temperatures, etc. Data are presented which show how the toughness and stiffness of an appliance-grade, impact polystyrene vary with impact velocity (or loading rate), temperature, fabrication method, and pigment level. The ability to survive multi-axial impact loads is strongly dependent on loading rate; a maximum in energy-absorbing ability was observed in the range 500-2000 in./in./min, where the failure mechanism changed from ductile to brittle.
