Technical Induction of Polyvinyl Butyral PVB Interlayer Film
By Peter Shin www.HelloGlass.com
Polyvinyl Butyral PVB Interlayer Film Polyvinyl butyral PVB interlayer film is the resin that compounded
from polyvinyl alcohol reacted with butyraldehyde. Polyvinyl butyral
PVB interlayer film is usually implied in the situation that needs
strong binding, toughness and flexibility. Polyvinyl butyral PVB
interlayer film as a protective interlayer film, is often used to make
automotive laminated glass and architectural laminated glass.
Polyvinyl butyral PVB interlayer film has many properties: Impact
resistance, great adhesion, sound control, UV-radiation filtered, and
good aging resistance.
Technical Parameters of Polyvinyl Butyral PVB Interlayer Film
Note: Following data is general number of PVB Film, and the data may
be different of different Polyvinyl Butyral manufacturers, because the
formula of manufacturing Polyvinyl Butyral may be different.

Polyvinyl Butyral PVB Interlayer Film for Laminated Glass
Polyvinyl Butyral PVB interlayer film have the impact resistance. The
single flat glass would lead to serious injuries to human being or
other properties when it’s broken, but Laminated glass with Polyvinyl
Butyral PVB interlayer film can stick the glass together when it’s
impacted, which can remain it’s safety. The safety of the laminated
glass with Polyvinyl Butyral PVB interlayer film is popularly
recognized as safety glass in architectural design.
And Polyvinyl Butyral PVB is good at penetration resistance, so is
better than tempered glass in Automotive windshield implication.
