Laminating Film
What is SGP Film
SGP is abbreviation of SentryGuard Plus Interlayer, it has stronger impact resistance and is a material with higher safety performance. SGP is a good choice for situations requiring stress, such as glass plank path and glass viewing platform. It is used in building exterior walls, and other places with safety requirements.
Advantages of SGP film
SuperSafeGlas Glass ionic interlayer is an ethylene and methyl acrylate copolymer of a kind of ionic film, containing about 1% of the sodium metal ions, the bond for the film and glass is the result of the ionic bonding effect, SuperSafeGlas film and glass bonding force than the compressive strength of PVB film and glass much higher. Its hardness is 100 times that of the traditional PVB interlayer material tenacity, strength is 5 times that of the traditional PVB interlayer material tenacity.
