Unformatted text preview: High-impact polystyrene (HIPS, PS-I) displays a less steep initial rise in the curve and, after reaching the yield point, pronounced deformation until rupture. This behaviour is characteristic of tough materials. The toughness of high-impact polystyrene increases with increasing rubber content. The stress-strain behaviour is dependent on the temperature and on the deformation rate....
