Crazing is the phenomenon that produces a network of fine cracks on the surface of a material, for example in a glaze layer. Crazing frequently precedes fracture in some glassy thermoplastic polymers.razing occurs in some thermoplastics such as acrylonitrile butadiene styrene (ABS plastic) when stressed. It is a typical response in rubber toughening, where crazes are initiated at the surfaces of the rubber particles added to toughen the material.
