TPU (Thermoplastic Polyurethane) interlayer films are high-performance, optical-grade materials used as the core interlayer in laminated glass, offering superior safety, durability, and versatility compared to traditional PVB/EVA films. ## Core Material Properties – **Optical Clarity**: Up to 90% visible light transmittance, low haze, no yellowing (aliphatic grades) – **Mechanical Strength**: High tensile strength, tear resistance, and impact absorption; prevents glass spalling – **Flexibility**: Maintains elasticity at extreme low temperatures (down to -68°C) – **Adhesion**: Strong bonding to glass, polycarbonate (PC), PMMA, and other substrates – **Weatherability**: Excellent UV resistance, hydrolysis stability, and long-term durability – **Processing**: No plasticizers; room-temperature storage; compatible with autoclave/vacuum lamination (100–130°C) ## Key Applications ### 1. Architectural & Building Safety – **Security Glazing**: Embassies, government facilities, banks, schools, and high-end commercial buildings (anti-burglary, blast resistance) – **Hurricane/Storm Resistant Glass**: Coastal structures and high-wind zones – **Sound Insulation Windows**: Reduces noise transmission for residential/commercial spaces – **Smart Glass Interlayers**: Enables integration of PDLC/EC films for switchable privacy glass ### 2. Transportation – **Automotive**: High-end windshields, sunroofs, and side windows (impact resistance, noise reduction) – **Rail**: High-speed train windshields and cabin windows – **Aerospace**: Aircraft canopies, helicopter windshields, and military transport glazing – **Marine**: Ship bridge windows and yacht glazing (saltwater resistance) ### 3. Defense & Security – **Bulletproof/Ballistic Glass**: Armored vehicles, military facilities, and VIP transport – **Blast-Resistant Glazing**: Critical infrastructure protection – **Anti-Riot Glass**: Correctional facilities and public safety zones ### 4. Specialty & Industrial – **Medical**: Radiation-shielding glass and cleanroom glazing – **PV & Smart Glass**: Lamination for solar panels and electrochromic systems – **Display & Electronics**: Touchscreen cover glass and flexible display laminates ##
