High-transparency thermoplastic polyurethane (TPU) is a premium elastomer tailored for the manufacturing and modification of ventilation duct systems, integrating excellent optical clarity, mechanical robustness, and environmental adaptability. Distinguished from conventional ventilation duct materials such as PVC or PE, this specialized TPU grade delivers unmatched performance advantages for scenarios requiring visual inspection of air flow, dust monitoring, or aesthetic integration of ductwork. ## Core Performance Characteristics 1. **Superior Optical Transparency** With a light transmittance of over 90% and haze value below 1%, the material enables clear observation of the internal condition of ventilation ducts, facilitating real-time monitoring of dust accumulation, blockages, or air leakage points. This feature is particularly critical for cleanroom ventilation systems, pharmaceutical production workshops, and food processing facilities where hygiene and operational safety are paramount. 2. **Excellent Mechanical Strength & Flexibility** Boasting a shore hardness range of 85A–95A, the TPU material balances high tensile strength (≥30 MPa) and elongation at break (≥400%), ensuring resistance to deformation under long-term air pressure and external impacts. Its inherent flexibility allows for easy fabrication of curved or customized duct sections without cracking, while maintaining structural stability across a wide temperature range of -40℃ to 120℃. 3. **Outstanding Chemical & Environmental Resistance** The material exhibits strong resistance to hydrolysis, oxidation, and corrosion by common industrial gases, as well as tolerance to mild acids and alkalis. It is non-yellowing under UV exposure for extended periods, making it suitable for both indoor and outdoor ventilation applications. Additionally, it complies with **RoHS** and **REACH** environmental standards, and food-contact grades meet **FDA** requirements, ensuring safety in sensitive environments. 4. **Easy Processing & Installation Compatibility**
This TPU grade is compatible with conventional processing methods including extrusion, injection molding, and thermal welding. It can be seamlessly bonded with standard ventilation duct accessories such as flanges, valves, and connectors, reducing installation time and costs. Its lightweight nature (density of 1.10–1.15 g/cm³) also lowers the load-bearing pressure on building structures compared to glass or metal duct components. ##
