Introduction:

Compared with PVB film, SGP film (ionized interlayer film) is stronger, more transparent. It is the best choice for ultra-white glass.
The tear strength of SGP film is 5 times than that of PVB film, and hardness is 100 times than that of PVB film. It's the best material for bullet proof glass.

Application:

Bullet proof glass
Explosion proof glass

Where to use:

Cash trucks, prisons, banks, glass open air ceilings, glass stairs (good bonding to metal), glass handrails, glass bridge
