TPU Film, also known as Thermoplastic Polyurethane Film or PU film, its raw material is thermoplastic polyurethane first developed in 1937. For decades, this material has been used to produce a unique category of films. TPU film outperforms common films such as PP, PE and PVC with its excellent and versatile performance characteristics.
Key Advantages of TPU Film
- Exceptional elongation and tensile strength for superior toughness and stretch resistance
- Excellent elastic memory that enables the film to recover its original shape well after deformation
- Strong chemical and microbial resistance for high stability in various complex working environments
- Outstanding low temperature flexibility that keeps the film soft and flexible without becoming brittle even in low temperature conditions
Classification of TPU Film
TPU film is mainly divided into three categories by chemical structure: polyester based, polyether based and polycaprolactone based. In addition, it can be classified into aromatic and aliphatic types by material properties. Aromatic TPU film has a wide application scope and is widely used in most consumer goods fields. Aliphatic TPU film, with its superior optical transparency and specific bonding performance, is specially applied in scenarios with high requirements for these two performance indicators.
