In the field of consumer electronics, various thermoplastic elastomers each play their own role. TPU, with its excellent wear resistance and mechanical strength, is commonly used in phone cases and smartwatch straps. TPE and TPR, known for their soft touch and easy colorability, are widely applied in headphone cables and device grip overmolding. TPV offers outstanding aging resistance and is often used for sealing precision components. Skin-friendly and stain-resistant TPV-SiR is becoming an ideal choice for wearable device bottom shells. TPEE, due to its high resilience, is frequently used in internal antennas and thin-walled structural parts.
