E&N Hongjia specializes in providing high-quality SGP interlayers. We are also a China SGP laminated glass supplier, with over twenty years of experience in the research, development, and production of laminated glass films, as well as extensive export experience.
SGP, short for SentryGlas Plus, is an ion-exchange polymer interlayer developed by DuPont (now Kuraray). SGP interlayer is also used in the manufacture of laminated glass, but it is not traditional PVB or EVA. SGP is a revolutionary material that endows laminated glass with unprecedented strength, stiffness, and durability. In short, SGP laminated glass is a structurally reinforced advanced glass that elevates the performance standards of safety glass to a whole new level.
SGP is called a "super interlayer" due to its unique ionomer structure. Unlike PVB's plasticized polyvinyl butyral, SGP's molecular structure gives it semi-rigid properties.
• Ultra-high strength and stiffness: SGP is 100 times stiffer than traditional PVB and has 5 times the tear strength. This means that, for the same glass thickness, laminated glass using SGP interlayer exhibits less bending deformation and greater load-bearing capacity.
• Excellent weather resistance: SGP is extremely resistant to moisture, high temperatures, and ultraviolet (UV) radiation. Unlike some interlayers, it does not easily fog or delaminate at the edges.
• Durable Optical Transparency: SGP boasts exceptionally high light transmittance and an extremely low Yellowness Index. Even after prolonged exposure to sunlight, it maintains crystal-clear transparency without yellowing.
• Stability in Extreme Climates: Whether in the humid heat of the tropics or the frigid temperatures of the Arctic, SGP interlayers maintain their mechanical properties and adhesive stability, making them ideal for high-performance glass.
E&N Hongjia Ionoplast interlayers offer exceptional strength and transparency, making them ideal for laminated glass structures. Compared to traditional interlayer films, SGP interlayers have more than five times the impact resistance of ordinary films, effectively improving the compressive strength and safety of glass. They are widely used in high-security buildings, glass curtain walls, large glass floors, glass skylights, and other projects.
Our Ionoplast SGP interlayers are suitable for the glass interlayer market, providing customers with higher product performance and a more stable production process. Whether for building facade glass, transparent structural glass, or high-strength glass applications, E&N's SGP interlayers ensure the safety and aesthetics of your project.

SGP interlayers Application
1. Structural & Safety Glass
SGP laminated glass is widely used in high-rise curtain walls, glass facades, and skylights, where superior mechanical strength and impact resistance are required. Compared with traditional PVB laminated glass, SGP interlayers provide higher tear strength and maintain structural integrity even under extreme loads.
2. Hurricane & Seismic Resistant Glazing
In areas with frequent hurricanes, earthquakes, or other natural disasters, SGP laminated glass ensures enhanced protection against flying debris and seismic vibrations, reducing the risk of breakage and ensuring building safety.
3. Balustrades & Canopies
For balustrades, handrails, and overhead glazing systems, SGP interlayers provide long-term stability and transparency. Even if the glass is broken, the interlayer holds fragments firmly, preventing falling hazards.
4. Architectural & Design Applications
SGP's optical clarity and UV resistance make it ideal for applications requiring both safety and aesthetics, such as museums, luxury storefronts, and interior partitions. Its ability to resist yellowing ensures long-lasting visual quality.
5. Transportation & Specialty Glass
SGP interlayers are also applied in railway, marine, and aerospace glazing, where extreme durability, vibration resistance, and long service life are essential.
