According to our previous paper, rubber deformation and crazing occur mainly in Fracture III (5).
They reported that impact strength improvement was caused by crazing in the case of the MS/SBS system, and by the voids generated in the neighborhood of particles in the case of PE/CaC[O.
In general, two types of plastic deformation mode exist in high molecular weight glassy amorphous polymer blends: crazing and shear banding.
The importance of this phenomenon lies in the fact that polymers are often used in crazing environments.
From the amount of crazing widening, the continuum stress acting in a direction normal to the craze-bulk interface can be deduced (4).
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.
