TPU – Flexibility Meets Strength
TPU
TPU Material Introduction
TPU (Thermoplastic Polyurethane) is a versatile elastomer that combines the elasticity of rubber with the processability of thermoplastics. Known for its outstanding abrasion resistance, flexibility, and mechanical strength, TPU offers excellent durability and resilience across a wide temperature range.
With superior impact strength, oil and chemical resistance, and transparency, TPU is widely used in footwear, automotive parts, cables, hoses, protective films, medical devices, and industrial components. Its easy processability through injection molding and extrusion makes it an ideal material for both consumer and industrial applications.
FAQ – TPU (Thermoplastic Polyurethane)
