Thermoplastic Polyurethane (TPU) has long been one of the most widely used elastomers in consumer products. It combines flexibility, impact resistance, and easy processing, making it suitable for applications such as phone cases, wearable devices, electronic accessories, and household products. However, as consumer expectations continue to rise, product designers are looking for materials that not only perform well when new but also maintain their appearance and tactile quali

FKM Alternatives for Wearable Products | PFAS-Free Materials Guide (2026) Discover why engineers are evaluating alternatives to FKM as PFAS regulations evolve. Compare HNBR, silicone, TPU, TPE, and next-generation silicone thermoplastic materials for wearable products. FKM Alternatives for Wearable Products: How PFAS Regulations Are Reshaping Material Selection For decades, FKM (Fluoroelastomer) has been one of the most trusted elastomer materials for demanding applications.

For more than a decade, TPU (Thermoplastic Polyurethane) has been one of the most widely used materials for smartwatch straps, children’s smartwatches, fitness bands, and many consumer electronic products. TPU is a mature engineering material known for its excellent abrasion resistance, flexibility, and ease of processing, making it a popular choice across the industry. However, when products require overmolding with rigid engineering plastics such as PC, ABS, or PA, manufact
