| Because of our quality and unique technologies, Sekisui
S-LEC Film is applied to many uses globally including buildings and automobiles.
The trust from our customers is based on three core technologies that
we are proud of. |
 |
| This co-extrusion technology
simultaneously extrudes several layers from a metallic mold to produce
a multi-layer PVB film. This technology has enabled Sekisui to produce
interlayer films with many new functions including sound control. |
|
 |
For example, the technology that
gives a color to a top shade of a vehicle's windshield is based on a partially
three-layered structure in which a tinted resin layer is bonded between
two transparent resin layers. By adjusting the thickness of the center
part of the tinted layer, the color of the tinted part gradually becomes
lighter toward its end. |
 |
| Furthermore, our Sound Acoustic
Interlayer Film, which has begun to be widely used for architectural and
automotive uses, has a sound control resin layer between two normal resin
layers. This sound control layer gives the interlayer film high sound control
property while the film itself maintains handling easiness and quality
similar to normal interlayer films. |
 |
| |
|
 |
Fine particles and other materials
with various functions are mixed into resins used in interlayer films.
This technology is vital for interlayer films to improve functions and to
ensure uniform qualities. |
|
 |
In Solar Control Interlayer Film
which marketing was started in 2002, fine particles that shield Infra Rad
rays are distributed. To maintain the desirable functions of interlayer
films such as transparency, this fine-particle distribution technology
is effectively applied. |
 |
| |
|
|
 |
| To ensure the safety of laminated
products, Sekisui has developed the capability to adjust the amount
of adhesion between glass and the PVB. By controlling this reaction,
our customers can consistently deliver good products to the marketplace. |
|
 |
A major function
that gives S-LEC film a quality advantage is high moisture resistance.
If moisture resistance is low, adhesive strength becomes deteriorated in
high humidity, and finally the interlayer film may come off from the glass
pane that does not function as laminated glass anymore. For a long time,
SEKISUI have been acknowledged an interlayer film supplier for Japanese
automobile industry that requires rigorous quality. And we have patented
this adhesive strength adjustment technology to ensure stable adhesive
strength of interlayer films. |
