Product Features
Safety: Hengte PVB heat-insulating interlayer film and composite glass layer have a strong adhesive strength, in the case of external impact, can prevent the impact of material penetration, even if the glass is broken, can still be attached to the glass fragments in the interlayer, will not fall off the four scattered injuries.
Energy Saving: PVB interlayer made of architectural, automotive laminated glass can effectively block infrared rays, have good thermal insulation performance, and high energy efficiency; the product has a high visible light transmittance, through the nano-insulating medium and the production process of reasonable adjustment of the visible light transmittance of the film as well as the adjustment of the coefficient of thermal insulation.
Anti-theft: PVB made of laminated glass is very tough, even if the burglars will break the glass, due to the intermediate layer with the glass firmly adhered together, but still maintains the integrity, so that the burglars can not enter the room.
Sound Insulation: As Hengte PVB film has the function of sound wave blocking, PVB laminated glass can effectively inhibit the spread of noise, especially in airports, stations, downtown, and road buildings on both sides of the installation of laminated glass, the sound insulation effect is very obvious.

Can Jiangsu Daruihengte Science & Technology Co., Ltd.'s PVB Heat Insulation Film be Used for Security or Shatterproof Applications?

In an era where safety, efficiency, and durability are paramount, the materials we rely on must deliver on multiple fronts. Jiangsu Daruihengte Science & Technology Co., Ltd., a recognized leader in the development of polyvinyl butyral (PVB) films, has revolutionized the industry with their PVB Heat Insulation Film. Widely used in various sectors, including photovoltaics, aerospace, defense, architecture, and automotive, this film offers an array of advantages beyond just thermal insulation. But can it also meet the demanding requirements of security and shatterproof applications? The answer, undeniably, is yes.

An Unyielding Barrier Against Impact
The core of PVB's unique appeal lies in its incredible adhesion properties. When used in laminated glass, Daruihengte’s PVB Heat Insulation Film forms a robust bond between the layers of glass, making it resistant to the types of impacts that would typically cause glass to shatter into dangerous shards. This high adhesive strength is particularly critical in security applications where breaking and entering are a concern.

In the unfortunate event of a glass breakage, the film effectively holds the shattered pieces together, preventing them from dispersing. This minimizes the risk of injuries from flying glass shards and, more importantly, maintains the integrity of the window, making it much harder for intruders to gain access. Whether in commercial buildings, homes, or vehicles, PVB laminated glass with heat-insulating film serves as a safeguard against both theft and injury.

Energy Efficiency with an Added Layer of Protection
While security is paramount, energy savings are also crucial for modern applications. Daruihengte’s PVB Heat Insulation Film doesn’t just block out the heat; it also blocks infrared radiation, significantly improving thermal insulation properties. The film allows high visible light transmittance while simultaneously enhancing thermal performance, offering a perfect balance between natural lighting and temperature regulation.

This efficiency is further elevated through nano-insulating technology, allowing for a more precise adjustment of the film’s thermal insulation coefficient. This results in a product that not only helps keep spaces cooler in the summer and warmer in the winter but also reduces energy consumption, leading to long-term cost savings.

A Robust Solution for Anti-Theft Needs
Security goes beyond just physical barriers; it extends to the resilience of the materials used in critical infrastructure. Laminated glass made with Daruihengte’s PVB heat-insulating film provides a tough and formidable defense against break-ins. Even in high-pressure situations where a glass layer might break under force, the film ensures that the glass fragments remain intact, keeping the structure secure.

This anti-theft characteristic makes the film ideal for use in high-risk environments such as banks, jewelry stores, and high-security buildings. The film provides a significant deterrent against theft, as burglars are unable to easily bypass the protection the film offers, even after attempting to break the glass.

Sound Insulation Benefits for Enhanced Comfort
As if its security and energy efficiency capabilities weren’t impressive enough, Daruihengte’s PVB Heat Insulation Film also offers exceptional sound insulation properties. By blocking sound waves, the film effectively reduces noise transmission, making it an ideal choice for buildings in noisy environments such as airports, train stations, and downtown areas. In these high-traffic locations, the film helps to maintain a quieter, more comfortable atmosphere inside.

Whether you’re in the bustling city center or near a busy highway, laminated glass with PVB heat-insulating film ensures that external noise is significantly reduced, providing a more tranquil and productive environment for both residential and commercial spaces.

A Global Standard in Quality and Innovation
Founded in 2010, Jiangsu Daruihengte Science & Technology Co., Ltd. has built a reputation for excellence in the development, manufacturing, and promotion of polyvinyl butyral (PVB) films. Their commitment to innovation is evident in their pioneering technology, including the first 3.6-meter-wide automatic die head for PVB film production in China.
