2025 Top 10 SGP Laminated Glass Factory in the world

Introduction to SGP Laminated Glass

SGP (SentryGlas Plus) laminated glass is a high - performance safety glass product. It consists of two or more layers of glass bonded together with a special SGP interlayer. This type of glass offers several outstanding properties. Firstly, it has extremely high strength. Compared with traditional PVB (Polyvinyl Butyral) laminated glass, SGP laminated glass can withstand much greater impact forces, making it an ideal choice for applications where safety and security are of utmost importance, such as in high - rise buildings, museums, and airports.

Secondly, SGP laminated glass has excellent clarity. The SGP interlayer is highly transparent, ensuring that the glass does not distort the view through it, which is crucial for architectural designs that require a clear and unobstructed visual effect. Additionally, it has good weather resistance. It can resist the effects of ultraviolet rays, moisture, and temperature changes, maintaining its performance and appearance over a long period.
