Laminated glass, composed of two or more pieces of glass and organic polymer intermediate film, because of good safety performance, strong defense, sound insulation and noise reduction advantages, laminated glass has been more and more widely used in the field of construction. According to the different intermediate film, it can be divided into PVB intermediate film laminated glass, SGP intermediate film laminated glass, EVA intermediate film laminated glass, colored intermediate film laminated glass and so on.
The life of laminated glass mainly depends on the material of the intermediate film. Because TPU material has excellent mechanical properties, ultraviolet resistance, hydrolysis resistance, high transparency and many excellent properties, has been widely concerned by the glass industry, TPU film in the field of architectural glass application advantages gradually highlighted, TPU intermediate film laminated glass gradually rise.
Application of TPU film in the field of architectural glass
Compared with traditional glass, laminated glass has more safety, sound insulation and radiation protection functions. Laminated glass fragments will be stuck to the film even if the glass is broken, effectively preventing the occurrence of splinter injuries and penetrating fall events. Normally, EVA intermediate film laminated glass is mainly used for indoor partition, PVB intermediate film laminated glass, SGP intermediate film laminated glass can be used for building broken bridge aluminum doors and Windows or curtain walls.
TPU film as an intermediate film can be bonded to glass and PC board, glass and acrylic board, glass and glass, etc. Compared with traditional PVB intermediate film, SGP intermediate film, TPU film has the following characteristics:
1. Higher intensity
TPU film has higher strength, higher load and wind pressure resistance under the same glass structure and thickness.
2. Better post-crushing safety
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 fog, and has higher permeability and visual effect after composite with glass.
Because TPU intermediate film has higher bonding properties, optical properties and mechanical properties, it is widely used in military and civilian fields, and the bulletproof glass made of this film can be used in aircraft, high-end bulletproof cars and banks.
TPU interfilm laminated glass has a large safety factor and obvious advantages compared with ordinary glass, and the requirements of modern architecture for glass provide a huge development space for TPU interfilm laminated glass. At the same time, affected by the policy, the overall trend of China's building materials is energy saving and environmental protection, and TPU as an environmentally friendly material is in line with China's current development policy.
TPU film: versatile intermediate film for bonding
TPU (thermoplastic polyurethane) film is a versatile material popular as an intermediate film for bonding a variety of substrates. Its unique properties make it an excellent choice for applications where traditional interlayers such as PVB and SGP may not be suitable.
One of the main advantages of TPU film is its ability to bond to a variety of materials, including glass, PC boards, acrylic sheets, and even other glass surfaces. This makes it a highly versatile choice for applications in industries such as automotive, construction and electronics.
TPU offers several advantages over traditional interlayer films. First, TPU film has excellent adhesion to different substrates, ensuring a strong and long-lasting bond. This is particularly important in applications where the bonded material is subject to mechanical stress or environmental factors.、
In addition, TPU films offer excellent optical clarity, making them ideal for applications requiring high transparency. This is particularly beneficial in the automotive industry, where TPU films can be used to laminate glass to improve safety and visibility.
Additionally, TPU films offer excellent resistance to yellowing and degradation, ensuring long-term performance and aesthetics. Its ability to maintain its performance over a wide temperature range also makes it suitable for different environmental conditions.
In addition, TPU films are known for their flexibility and impact resistance, which further enhances their suitability for adhesive applications. Its ability to conform to curved surfaces and withstand dynamic loads makes it a reliable choice for demanding applications.
In summary, TPU film has become a versatile intermediate film for bonding to a variety of substrates. Its unique combination of properties, including adhesion, optical clarity, durability and flexibility, make it the first choice for applications where traditional interlayers may not deliver the required performance. As industries continue to seek innovative solutions to bonding challenges, TPU films are likely to play an increasingly important role in a variety of applications.
