Practical application of TPU film in the field of architectural glass

Laminated glass, composed of two or more pieces of glass and organic polymer interlayer, has been more and more widely used in the field of construction because of its good safety performance, strong prevention, sound insulation and noise reduction. According to the different interlayers, it can be divided into PVB laminated glass, SGP laminated glass, EVA laminated glass, colored laminated glass, etc.
The life of laminated glass depends mainly on the material of the interlayer. Due to the excellent mechanical properties, ultraviolet resistance, hydrolysis resistance, high transparency and many other excellent properties of TPU material, it has received extensive attention from the glass industry, and the application advantages of TPU film in the field of architectural glass have gradually become prominent, and TPU interlayer laminated glass has gradually risen.
Application of TPU film in the field of architectural glass
Laminated glass has the functions of safety, sound insulation and radiation protection. Laminated glass allows the fragments to stick to the film even if the glass is broken, which effectively prevents the occurrence of puncture injuries and penetrating falls. Normally, EVA laminated glass is mainly used for indoor partitions, and PVB laminated glass and SGP laminated glass can be used for aluminum doors and windows or curtain walls of building broken bridges.
As an interlayer, TPU film can bond glass and PC board, glass and acrylic sheet, glass and glass, etc., and has the following characteristics:
1. Higher strength
TPU film has higher strength, higher load and wind pressure resistance with the same glass structure and thickness.
2. Better safety after crushing
The TPU film has higher tensile strength and tear strength, and the laminated glass also has strong support after breaking.
3. Better optical performance
TPU film has higher light transmittance and lower haze, and has higher transparency and visual effect after being compounded with glass.
Due to its higher bonding properties, optical properties and mechanical properties, TPU interlayer film has been widely used in military and civilian fields, and bulletproof glass made of this film can be used in aircraft, high-end bulletproof cars and banks.
