Thermoplastic Polyurethane (TPU) film is an advanced interlayer material specially developed for laminated glass, serving as an ideal alternative to traditional PVB interlayer. With outstanding flexibility, high adhesion strength and superior weather resistance, TPU interlayer perfectly bonds glass panels to form safe, multi-functional composite laminated glass.It delivers excellent impact resistance: once the glass cracks under external force, broken fragments will be tightly adhered to the TPU film without splashing, greatly reducing injury risks. Besides core safety performance, TPU laminated glass features high light transmittance, stable optical property, low yellowing rate under long-term UV exposure, and remarkable sound insulation & heat insulation effects.Compared with conventional PVB, TPU interlayer boasts wider operating temperature range, superior hydrolysis resistance and long service life. It is widely applied in architectural facade glass, balcony railings, shower room glass, automotive sunroofs, vehicle side windows, bulletproof & explosion-proof safety glass, as well as high-end decorative laminated glass. Our customized TPU raw materials can be adjusted in hardness, thickness and functional formulas to meet diverse customer requirements for construction, transportation and security fields.
Detailed Technical Version
TPU Interlayer Raw Material for Laminated Glass — Product Application IntroductionThermoplastic Polyurethane (TPU) is a thermoplastic elastomer material adopted as the core interlayer medium of laminated safety glass. Through high-temperature hot-pressing lamination process, TPU film fuses seamlessly with two or more pieces of float glass, tempered glass or patterned glass, constructing integrated laminated glass structures with comprehensive safety and functional advantages.Core Material Advantages Ultimate Safety Performance TPU possesses ultra-high peel strength and tensile toughness. Under impact, penetration or blasting loads, it firmly locks all broken glass shards, eliminating secondary damage caused by scattered glass pieces. It also provides reliable anti-penetration capacity for explosion-proof and anti-theft glass scenarios. Stable Optical & Anti-UV Property Premium glass-grade TPU raw material adopts anti-yellowing UV stabilizer formula, featuring high visible light transmittance, low haze value and long-term anti-discoloration performance. It maintains consistent transparent appearance after years of outdoor exposure, outperforming ordinary PVB interlayers in anti-aging capacity. Superior Environmental Adaptability The material shows excellent hydrolysis resistance and moisture stability, with no delamination, bubbling or whitening in high-humidity, high-temperature environments. Its applicable temperature range covers low-temperature cold regions and high-temperature sun-exposed areas, solving the failure defects of traditional interlayers under extreme climates. Multifunctional Additional Value Custom functional TPU grades support sound insulation, infrared heat insulation, matte frosted, colored and bulletproof modified formulas. The thermoplastic characteristic enables reprocessing and recycling of leftover TPU raw materials, lowering production waste costs for manufacturers. Main Application Scenarios Construction field: High-rise building curtain wall laminated glass, indoor balustrade glass, bathroom shower glass, stair handrail glass, skylight daylighting glass Transportation field: Automobile panoramic sunroof, new energy vehicle side window glass, yacht & ship cabin window glass, high-speed rail partition glass Safety & special industry: Bulletproof security glass, explosion-proof barrier glass, museum anti-theft display glass, high-end decorative art laminated glass Processing CompatibilityOur glass lamination TPU raw materials match fully-automatic hot roller laminators and autoclave processing lines.
