Mechanical Properties of Thermoplastic Elastomer Blends
Summary
Thermoplastic elastomer blends combine the elasticity of rubbers with the melting and reshaping capabilities of thermoplastics, yielding materials that can be repeatedly processed without permanent crosslinking. Mechanical performance is governed by the interplay between phase-separated hard domains, which carry load and confer dimensional stability, and soft domains, which allow extensibility and energy dissipation. Key properties such as tensile strength, elongation at break, modulus and abrasion resistance emerge from composition, molecular weight distribution and domain morphology. By blending block copolymers like styrene-ethylene/butylene-styrene (SEBS) with polyolefins, polyurethanes or compatibilisers, it is possible to tailor crystallinity, interfacial adhesion and dispersion. Processing conditions—temperature, shear rate and cooling profile—further refine domain size and connectivity, influencing dynamic mechanical response and fatigue life. These blends find widespread application in automotive interiors, medical devices and consumer goods, offering recyclability, low volatile organic compound emissions and a sustainable alternative to traditional vulcanised rubbers.
