SGP film has high strength and shearability. Its bearing capacity is 2 times that of PVB film of the same thickness. After laminating with SGP film, it has good resistance to moisture, does not require edge sealing treatment, and there is no need to worry about the risk of delamination. Moreover, the yellowing coefficient is less than 1.5, and the tear strength of SGP laminated film is 5 times that of PVB. SGP laminated glass is not sensitive to external climate changes and will not turn yellow after long - term use. When SGP laminated glass is hit by a heavy object, even if the glass is completely broken, the glass will not fall off.

SGP ionic interlayer film has high strength and shear modulus, with excellent mechanical properties. Its shear modulus is more than 50 times that of ordinary PVB, and its tear strength is 5 times higher than that of ordinary PVB. After laminating with SGP film, when the glass is under stress, there is basically no sliding between the two pieces of glass in the interlayer, and the two pieces of glass work as a single-piece glass of equal thickness. In this way, the bearing capacity is twice that of ordinary PVB laminated glass of equal thickness. At the same time, under the same load and equal thickness, the bending deflection of SGP laminated glass is only 1 / 4 of that of ordinary PVB laminated glass. Due to the increased bearing capacity and reduced deflection, the glass thickness will be correspondingly reduced. It is possible to reduce the glass usage by about 40%, and correspondingly reduce the self-weight of the curtain wall. This is not only beneficial to the main structure design, but also saves materials and energy.
It has good edge stability and can be used exposed without edge sealing:
Edge stability refers to the durability of the edge of laminated glass exposed to the atmosphere. PVB laminated glass is not resistant to moisture. Under the action of water vapor, it is easy to delaminate and separate, so the exposed edges need edge sealing treatment. On the contrary, Tongdun SGP laminated glass has good edge stability, is not sensitive to moisture, and will not delaminate or separate under exposed conditions. It can be used with open edges without edge sealing. Therefore, SGP laminated glass can be conveniently used for components with exposed edges such as balustrades, canopies, glass curtain walls, and glass sunshades without taking any special edge sealing measures.
After the glass is broken, it retains sufficient residual bearing capacity and will not fall as a whole:
Ordinary PVB laminated glass, especially tempered laminated glass, will produce large bending deformation once the glass is broken, and there is a risk of the whole piece falling off. The risk is even greater when the glass is horizontally installed on the skylight. There have been cases where the glass has fallen as a whole. SGP interlayer film laminated glass has good integrity. Its tear strength is 5 times that of ordinary PVB interlayer film. Even if the glass is broken by accident, the SGP interlayer film can still bond the broken glass to form a temporary structure after damage. Its bending deformation is small, and it can still bear a certain amount of load without the whole piece falling. This greatly improves the safety of the glass.
It is colorless, transparent, not easy to change color, and has good transparency:
The SGP laminated film itself is colorless and transparent, and has good weather resistance and is not easy to turn yellow. The yellowing coefficient of the SGP film is less than 1.5, while that of the PVB film is 6 - 12. Therefore, SGP laminated glass can better meet the architectural art requirements of architects. If ultra-clear glass (low-iron glass) and SGP interlayer film are used to make ultra-clear laminated glass, it will have a crystal-clear optical effect.
Mechanical properties of laminated glass with ionic interlayer film:
The working performance of several pieces of glass laminated together depends on the mechanical properties of the interlayer (interlayer film). If the shear modulus G and tear strength f of the interlayer film are very small (ordinary PVB laminated glass), when the laminated glass is bent, a large slip will occur in the interlayer, and the glass will slide relative to each other. In fact, the interlayer film does not play the role of connecting the glass into a whole. These pieces of glass seem to be laminated together, but actually they still work independently. The bearing capacity is only the sum of the individual bearing capacities of each piece of glass. On the contrary, if the shear modulus G and tear strength f of the interlayer film are very high (SGP laminated glass), when the laminated glass is bent, the slip amount of the interlayer film is extremely small. At this time, several pieces of glass can work together, just like a single piece of glass.
