Features of S-LEC EN Film 2

1) Safety
Compared to the PVB interlayer film (S-LEC Film), EN Film more effectively prevents glass from shattered. If glass is broken when a person collides, this EN Film in the glass minimizes the person's injury.

2) Security
EN Film has high crime prevention performance same as the one of the PVB interlayer film (S-LEC Film) if it is bonded with PET film. Moreover, the film's crime prevention performance is further improved by bonding with polycarbonate.

3) UV Filtering
EN Film screens about 99% of UV rays similar level to the PVB interlayer film (S-LEC Film).

Penetration Resistance of EN Film
Ball Drop Test (JIS R 3212)
The test checks penetration status of a 300m*300mm laminated glass after a ball 2260g in weight,
82mm in diameter is dropped on its center. (At 23°C)
