Architecture-grade PVB interlayer films and automotive-grade interlayer films.

PVB interlayer film (polyvinyl butyral film) is a special resin material that is widely used in the field of safety glass.

According to product types and application fields, it can be divided into Architecture-grade PVB interlayer films and automotive-grade interlayer films.

Architectural-grade PVB is mainly used in the production of laminated glass for building glass curtain walls. Its working principle is to sandwich a layer of PVB film between two pieces of glass and undergo high-pressure compounding, heating and other processes to form laminated glass with special properties.

Architectural grade PVB laminated glass has the following main advantages:

1. Safety: PVB interlayer film can effectively prevent glass from splashing when it is impacted or broken, thereby reducing the risk of injury to personnel.

2. Anti-theft: PVB laminated glass is very tough. Even if it is cracked, because the middle layer and the glass are firmly adhered together, it can still maintain structural integrity and prevent glass penetration, which has a certain anti-theft function.

3. Ultraviolet filtration: PVB interlayer film can filter more than 99% of ultraviolet rays in sunlight to protect people’s health.

4. Sound insulation: PVB interlayer film can weaken the sound vibration through the glass, providing a quieter and more comfortable indoor environment.

5. Energy-saving effect: By adjusting the thickness and formula of the PVB film, the light transmittance of the laminated glass can be controlled to control sunlight and heat, thereby reducing the energy consumption of the building and improving indoor comfort.

In addition, the construction-grade PVB interlayer film also has the characteristics of being recycled, processed and reused, and meets environmental protection requirements. In the construction and decoration industry, PVB interlayer film has a wide range of applications, such as high-rise buildings, commercial buildings, home decoration and other fields.

Automotive grade PVB film is sandwiched between two layers of glass. This structure gives the glass higher strength and impact resistance. At the same time, when the glass is shattered by impact, the PVB film can keep the fragments aggregated to prevent the fragments from flying and hurting people, greatly improving the safety of passengers.

In the mean time, automotive grade PVB film has the function of blocking ultraviolet rays. Its blue belt, green belt, etc. can effectively prevent ultraviolet radiation from shining on drivers and reduce the occurrence of traffic accidents. At the same time, due to its poor thermal conductivity, it is more comfortable than vehicle front windshields without PVB interlayer film, which can save energy consumption of car air conditioners and avoid driver inconvenience after being exposed to the sun for a long time.

Automotive grade PVB laminated glass has the following main advantages:

1. High safety: The biggest advantage of PVB glass is its safety. When subjected to impact or external force, even if the glass breaks, the PVB intermediate layer will stick the fragments together and prevent them from flying, thus greatly reducing the risk of injury.

2. Good sound insulation effect: The PVB middle layer has good sound insulation performance, which can effectively reduce the spread of noise and provide a quieter and more comfortable indoor environment.

3. Anti-UV: PVB film can filter out more than 99% of UV rays, protect indoor items from UV damage, and is also beneficial to human health.

4. Energy saving: PVB glass can control the light transmittance by adjusting the thickness and formula of the PVB film to control sunlight and heat, reduce the energy consumption of the building, and improve indoor comfort.

5. High aesthetics: The appearance of PVB glass is smooth and beautiful, which can increase the overall beauty of the building.

With the continuous development of the automotive industry, the application of automotive-grade PVB films is becoming more and more widespread. Not only is it used in front windshields, it is also increasingly used in the manufacture of side panels and roof glass for luxury vehicles to improve safety and reduce noise and light rates.

Overall, automotive-grade PVB films play an indispensable role in automobile manufacturing with their unique properties.
