One of the most common unexpected brittle failures of all thermoplastic materials is environmental stress cracking. ESC occurs when polymers are exposed to liquid chemicals that accelerate the crazing process, which results in cracking at pressures below standard air temperature. The study of ESC has application within the automobile industry, where the need to keep polymers stable is paramount
