SGP laminated tempered safety glass

SGP is called the ionic interlayer film (SentryGlas Plus), which is a high-performance interlayer developed by DuPont.

Everyone is watching:

ꄲNext： Tempered clear laminated glass with PVB or SGP used for railings,buildings etc.

SGP is called the ionic interlayer film (SentryGlas Plus), which is a high-performance interlayer developed by DuPont.

Performance:

1. Excellent mechanical properties and high strength. At the same thickness, the SGP interlayer bearing capacity is twice that of PVB; under the same load and thickness, the bending deflection of SGP laminated glass is one quarter of PVB;

2, tear strength. At the same thickness, the PVB interlayer film has a tear strength of 5 times that of PVB, and can be bonded to the glass in the case of tearing without causing the entire glass to fall.

3, strong stability, moisture resistance. SGP laminated glass is colorless and transparent, anti-ultraviolet. After long-term sun and rain, it is not easy to turn yellow, and the yellowing coefficient is less than 1.5. However, the yellowing coefficient of PVB interlayer film is 6~12. Therefore, SGP is the darling of ultra-white laminated glass.

4.The SGP interlayer is marketed as a product that offers 5-times the tear strength and 100-times the rigidity of standard PVB. This means that in the unlikely event of both panes of toughened glass breaking then the SGP will, in most applications, hold the glass in an upright position. Comparitively, if both panels of glass smashed with a PVB interlayer (it is very important to understand that this is an extremely unlikely occurrence) then the interlayer would not hold the panel in an upright position.
