Mechanical Properties and Performance Criteria Beyond the basic family classification, the specific mechanical properties of plastic molding materials dictate their suitability for demanding applications. Within this group, materials like polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC) are valued for their chemical resistance and flexibility.
Selecting Right Material for Injection Blow Thermoforming: Key Properties and Considerations
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. 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.
Equally important is resistance to environmental stress cracking (ESC), a phenomenon where a material fails under constant tensile stress when exposed to certain chemicals. 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.

Engineers must also evaluate the material’s behavior across temperature ranges; some polymers remain stable in cryogenic environments, while others are engineered to withstand continuous exposure to high heat without deforming or melting. Flame retardants are critical for electronics and construction applications, ensuring materials meet strict safety standards.
