Clear TPU (Thermoplastic Polyurethane) Film is a high-performance, transparent plastic film known for its exceptional clarity, flexibility, and durability. It combines the optical properties of glass with the toughness of plastic, making it ideal for applications requiring impact resistance, elasticity, and weatherproofing.
Features
Material & Optical Properties
Base Material: Thermoplastic Polyurethane (TPU) – polyester or polyether-based.
Transparency: Up to 92% light transmission (similar to glass).
Clarity: Low haze (< 3%) for distortion-free visibility.
Surface Finish: Glossy, matte, or anti-glare options.
Mechanical & Chemical Performance
Elasticity & Flexibility: Can stretch 300–600% without permanent deformation.
Tear & Puncture Resistance: 5–10x stronger than PVC or PE films.
Abrasion Resistance: Withstands repeated friction (e.g., screen protectors).
Chemical Resistance: Resists oils, solvents, and UV degradation.
Environmental Durability
Temperature Range: -40°C to +80°C (short-term up to +120°C).
UV Stability: 5+ years outdoors (with UV inhibitors).
Waterproof & Moisture-Resistant: 100% impermeable.
Functional Enhancements
Self-Healing Properties: Minor scratches disappear with heat (optional).
Adhesive Backing: Peel-and-stick versions for easy installation.
Printability: Compatible with screen printing, digital printing, and embossing.
Advantages
Superior Clarity
Near-glass transparency with no yellowing over time.
Extreme Flexibility
Can be bent, folded, or thermoformed without cracking.
High Impact Resistance
Protects surfaces from scratches and drops.
Weatherproof
Performs in rain, snow, and UV exposure.
Eco-Friendly
Recyclable and free from phthalates/BPA.
Versatile Processing
Easy to cut, weld (RF/ultrasonic), or laminate.
