Both polyester-based and polyether-based TPUs are thermoplastic polyurethane materials, yet they exhibit distinct performance characteristics. Polyester-based TPU offers superior mechanical strength, as well as enhanced resistance to abrasion, oil, and chemicals, making it suitable for high-performance applications such as industrial components, footwear materials, and automotive parts.
In contrast, polyether-based TPU excels in resistance to hydrolysis, low temperatures, and microbial degradation, making it ideal for medical devices, underwater equipment, and products exposed to long-term humid conditions. Overall, polyester-based TPU is better suited for dry environments requiring abrasion and oil resistance, whereas polyether-based TPU is preferable for humid and low-temperature environments; material selection should be based on a comprehensive assessment of actual operating conditions.
