Company tests show the material is highly resistant to surface crazing caused by food and beverage contact or extensive dishwashing, out-performing competitive resins such as polycarbonate, SAN and straight acrylic.
They concluded that crazing is the dominant deformation mechanism for high impact polystyrene (HIPS) blends, regardless of the strain rate, and the difference in capability to initiate crazes is a dominant factor for the significantly different fracture energy of the two HIPS at the highest strain rate.
A review of the literature addressing crazing in polymers indicates that a number of different models have been proposed to predict craze formation, growth, and subsequent separation in polymers.
The occurrence of crazing in semicrystalline polymers, particularly in polyethylene, is well documented [1, 2].
There is also evidence of multiple crazing in PE100 and BMPE, but there are fewer secondary crazes.
The residual mechanical properties of crazed polycarbonate were then correlated to the crazing stress, relative craze density and strain rate.
The Design of Experiments (DOE) approach was used to build quantitative empirical models of the residual mechanical properties of crazed polycarbonate as functions of relative craze density, crazing stress, and strain rate.
Crazing in polymers may arise at crack tips owing to high stress concentration, as reviewed by Kramer and Berger [1, 2].
Results will be used to support the development of models to predict stress-induced crazing in these structures.
2) SEM (scanning electron microscope) and TEM (transmission electron microscope) observations on the broken surface revealed that shear yield and crazing occurred in a whitened portion, and crazing was observed only near the surface of the broken section in a non-whitened portion.
The toughening mechanism investigation shows that a widespread crazing zone is generated in the crack tip damage zone.
