TPU Waterproof Thermoplastic Urethane Film
This 80 μm thermoplastic urethane film features excellent yellowing resistance and is specifically designed for medical device coating, surgical drapes, gowns, medical packaging, and wound dressing applications.
Key Applications
- Protective Films: Excellent abrasion and impact resistance for electronic devices, automotive components, and industrial equipment
- Membranes and Liners: Superior chemical resistance for water/fuel tanks, inflatable structures, and medical packaging
- Apparel and Textiles: Enhanced water resistance and breathability for rainwear, sportswear, and outdoor gear
- Medical Devices: Biocompatible coatings for catheters, wound dressings, and surgical drapes
- Flexible Packaging: Excellent sealability and puncture resistance for food and pharmaceutical packaging
- Laminates and Composites: Enhanced strength and flexibility for aerospace, automotive, and construction applications
Material Types
Polyester-based TPU Films
These films utilize polyesters as the soft segment, providing high tensile strength, excellent abrasion resistance, and superior resistance to oils, chemicals, UV rays, and hydrolysis. Ideal for industrial, automotive, and apparel applications.
PEUR Films
Featuring 'PE' as the soft segment, these films offer high flexibility, elasticity, excellent low-temperature flexibility, transparency, and water vapor permeability. Commonly used in medical, food packaging, and inflatable product applications.
