Expertise
We were world’s first with this technology and still are industry leader in sound acoustic automotive interlayer films, enhancing comfort in the majority of cars around the globe.
We work closely with leading glass manufacturers. Where possible, our technical engineers assist customers by finding solutions to increase production line efficiency.

Multi-layer Technology
The sound-insulation succes of SEKISUI S-LEC™ Acoustic Film lies in a three-layer extrusion technology: A soundproof layer (core layer) is placed between two conventional interlayer films (outside layers). This method significantly improves sound insulation performance, while maintaining the same basic benefits of S-LEC™ Clear Film (Standard Interlayer).
Laminated glass with S-LEC™ sound insulation interlayer film works best at dampening the 1,000 to 4,000Hz sounds humans hear most. This opens possibilities for more quiet, creative spaces. S-LEC™ Sound Acoustic Film, with superior dampening performance, reduces glass vibration and blocks outside noise.

Minimize distraction with clear Head-Up Display images
Many 2019 launched premium- and mid-range vehicles use our Wedge-shaped S-LEC™ Film for clear performance of the Head-Up Display functionality. The appearance of double images belongs to the past. This is yet another invisible example where our technology truly supports in 'leading the way'!

Customized design for electrical vehicles
In close cooperation with a leading producer of electric vehicles we developed unique S-LEC™ PVB Film with natural gradient shading, applied in the roof and front/rear window of 2 recent models. The gradual transition from transparent to tinted glazing perfectly fits the modern design of the electrical vehicles.

European Research Centre at Brightlands Chemelot Campus
In 2017 SEKISUI S-Lec B.V. established its European Research Center (ERC) at Brightlands Chemelot Campus in Sittard-Geleen (the Netherlands). This landmarks a substantial boost for our technology evolution, product development, and global business in interlayer film for laminated glass, through the fusion of resources from SEKISUI and Brightlands.

Advantages
Noise Reduction
S-LEC™ Sound Acoustic Film brings peace and calmness to the interior of the car by significantly reducing noises coming through glass from engine, tires, wind and rain.
Safety
S-LEC™ PVB film with high impenetrability, will protect the glass from shattering, saving visibility and preventing shattering to minimize the likelihood of occupant injury.
UV-Filtering
Sunbeams contain ultraviolet rays which can cause sunburns and color fade for car interior. S-LEC™ PVB Film filters more than 99% of these harmful ultraviolet rays.
