🌟 Material Advantages
-
TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics, combining strength and flexibility.
-
Compared to generic TPE, TPU is more rigid, durable, and abrasion-resistant.
-
Offers excellent bed adhesion, minimal warping, and high transparency.
💪 Performance Benefits
-
High resilience & mechanical strength (bending, tension, compression).
-
Abrasion, chemical, and aging resistance.
-
Waterproof, cold-resistant, and UV-resistant (anti-yellowing, withstands sun exposure).
-
Softer than TPU-95A, but stronger than elastic filaments.
🎯 Wide Applications
-
👟 Footwear & soles (sports shoes, golf shoes, prototypes)
-
⚙️ Machinery & automotive parts
-
📱 Phone cases & electronic accessories
