SGP intermediate membrane is a new polymer material with high elastic modulus and high polymer bond.

First, product features and advantages

1, with high strength and shear modulus, excellent mechanical properties. The shear modulus of SGP is 100 times that of PVB, and the tearing strength is 5 times higher than PVB. After the SGP is laminated, the adhesive layer between the two pieces of glass basically does not slide when the glass is stressed, and the two pieces of glass work as a single piece of glass of equal thickness. In this way, the bearing capacity is twice that of PVB laminated glass of equal thickness; At the same time, under the same load and the same thickness, the bending deflection of SGP laminated glass is only 1/4 of that of PVB laminated glass.

2, excellent glass broken safety performance and anti-intrusion performance. Ordinary PVB laminated glass, especially tempered laminated glass, once the glass is broken, it will have a great bending deformation, and there is a danger of falling off the whole piece, and the risk is greater when the glass is horizontally installed on the top of the lighting. SGP intermediate film laminated glass integrity is good, even if the glass is broken, SGP film can also bond broken glass to form a strength structure after damage, its bending deformation is small, but also can withstand a certain amount of load without the whole piece falling. This greatly improves the safety of glass.

3, with good side stability, can be used on the side. Edge stability refers to the durability of the edge of laminated glass exposed to atmospheric conditions. PVB adhesive is not resistant to moisture, easy to unglue and separate under the action of water vapor, requiring the exposed edge to be sealed. The SGP film has good edge stability, is not sensitive to moisture, low hygroscopicness, and will not open and separate when used under exposed conditions. It can be used with open edges without sealing edges.

4, colorless and transparent, not easy to change color, excellent permeability. The SGP film itself is colorless and transparent, and has good weather resistance, and the yellowing coefficient is less than 1.5, while the yellowing coefficient of PVB film is 6 to 12. At the same time, SGP film can retain its original transparency after many years of use, while ordinary PVB intermediate film will gradually become more yellow during use.

5, excellent weather resistance, not easy to age. After years of aging tracking test by authoritative institutions, there is still no obvious bubble and yellowing phenomenon after 20 years.

6, excellent adhesion with metal. SGP has high bond strength with metals, such as aluminum, steel, and copper. The laminated glass made of SGP and metal wire, mesh and plate can greatly improve the performance of glass after breaking, and has strong anti-damage and anti-intrusion performance.

2. Scope of application:

1, building external curtain wall: point installation of external curtain wall, glass ceiling, glass floor, glass railing.

2, safety protection glass: wind glass, explosion-proof glass, anti-violence intrusion glass.

3. Projects that need to emphasize the glass permeability effect, multi-layer composite laminated glass or places where ultra-white glass is used.

4, large size building glass

5, with metal composite glass

6, the possibility of application in the field of car sunroof, bullet train, aviation, navigation
