An impact perfbimance test for materials in accordance with BS EN12600:2002 has been performed on the four given samples. The performance classification of the all test samples is Classification 1 (C) 1.
Performance Test
Sample:5mm tempered glass + 1.14 PVB + 5mm tempered glass
Impact Test: In accordance with Clause 5.1 of ANSI Z97.1-2015 Type 4
Thermal Test: In accordance with Clause 5.3 of ANSI Z97.1-2015
The distinguish between PVB & SGP:
1.The shear modulus of SGP is 50 times of that of PVB.
2.The Tear strength of SGP is 5 times of that of PVB.
3.The bearing capacity of SGP is 2 times of that of PVB.
4. The bending of SGP is only 1/4 of that of PVB.
In a word, SGP has better performance than PVB, and it's widely applied in glass path, glass ceiling, glass floor, Stair Treads,etc.
Longlass Laminated Glass Features
Energy saving
When sunlight directly shines on a piece of colorless laminated glass, the PVB interlayer film can absorb most of the heat and only radiate a part of the heat back indoors, making the indoor and outdoor heat difficult to conduct, reducing heat energy consumption, thereby maintaining indoor temperature and saving air conditioning Energy consumption.
Security
it can withstand the penetration of accidental impact. Once the glass is damaged, its fragments will still stick together with the intermediate film, which can avoid personal or property damage caused by the glass falling, and the whole piece of glass remains intact and can continue to withstand impact, wind and rain
Sound insulation
The interlayer film has the function of blocking sound waves, so that the laminated glass can effectively control the transmission of sound and play a good sound insulation effect.
Noise reduction
In the process of sound wave transmission, the glass on both sides of the film is reflected back and forth, and is attenuated and absorbed by the soft film. Generally, the noise can be reduced by 30-40 dB. The thicker the film, the better the noise reduction effect.
Decorative effect
The laminated glass can be sandwiched with various patterns, which can achieve the decorative effect, and there are also decorative effects such as ice glass.
UV resistance
The interlayer film has the function of filtering ultraviolet rays; the special PVB film can make laminated glass weaken the transmission of sunlight, effectively block ultraviolet rays, reduce the fading of indoor fabrics. The color PVB interlayer film has different light transmittance, and can control the ultraviolet and heat gain as needed. It will not block the penetration of visible light .
