Mechanical Properties and Performance Criteria Beyond the basic family classification, the specific mechanical properties of plastic molding materials dictate their suitability for demanding applications. Impact resistance, tensile strength, and fatigue resistance are crucial for parts subjected to physical stress or repeated loading.
Core Polymer Families: Decoding Mechanical Behavior and Environmental Resistance
For instance, polycarbonate (PC) is chosen when extreme durability and transparency are required, while acrylonitrile butadiene styrene (ABS) offers a robust balance of toughness, rigidity, and ease of processing. Equally important is resistance to environmental stress cracking (ESC), a phenomenon where a material fails under constant tensile stress when exposed to certain chemicals.
Chemical Resistance and Environmental Stress Cracking In industrial and consumer applications, exposure to chemicals is a common reality, making chemical resistance a non-negotiable attribute. From the housing of your smartphone to the intricate components within a medical device, the polymers selected dictate not only the form but also the function, durability, and cost of the final product.

Flame retardants are critical for electronics and construction applications, ensuring materials meet strict safety standards. Fillers such as glass fiber or carbon black not only improve mechanical strength and dimensional stability but also influence electrical conductivity, allowing a plastic to function as an insulator or a conductor depending on the formulation.
