Advantages of EVA Interlayer Film Compared to PVB Interlayer Film
By Peter www.evafilms.com updated on 2012-08-16
EVA Interlayer Film and PVB Interlayer Film are both used to make
safety laminated glass. PVB Interlayer Films have been used to make
laminated glass far before EVA Interlayer Films have been used to make
laminated glass.
Laminated glass is popularly used as safety glass to protect people
and property. +PVB Introduction:
PVB stands for Polyvinyl butyral. It is made of polyvinyl alcohol by
reaction with butyraldehyde. The major application is laminated safety
glass for architectural building windows and automobile windshields.
(learn more go to wiki: http://en.wikipedia.org/wiki/Polyvinyl_butyral
) . +What’s Wrong with PVB:
However, PVB Interlayer Film is very sensitive to moisture, which
makes it difficult to store and process. It requires high standard of
processing condition to care about humidity.
So EVA Interlayer Film is emerging and playing a more and more
important roll in laminated glass and decorative art glass world. +EVA Introduction:
EVA is the copolymer of ethylene and vinyl acetate. The weight percent
vinyl acetate usually varies from 10 to 40%, with the remainder being
ethylene. (learn more go to
wiki:http://en.wikipedia.org/wiki/Ethylene-Vinyl_Acetate ) Architectural EVA(Ethylene-vinyl acetate) Interlayer Film can be used
in Vertical Safety Glass, Sloped Safety Glass and Overhead Safety
Glass. Architectural EVA Interlayer Film owns high-performance safety
function properties, reliable and long-time weather resistance. The
standard thickness of Architectural EVA Interlayer Film is 0.38mm and
0.76mm. Architectural EVA Interlayer Film past the safety standard of
the safety laminated glass with PVB(Polyvinyl butyral) Interlayer Film
in China. +EVA Interlayer Film has Great Properties
-Great Light Transmission, ≧92%
-Almost Totally UV Blocked, ≧99%
-Long Weather Resistance, ≧15 years
-Great Tensile Strength, ≧21 Mpa
-Good Adhesive Strength, ≧50N /cm
-Qualified Impact Resistance As PVB Does
-Qualified Moisture Resistance As PVB Does +Advantage of Making Laminated Glass with EVA Film Compared with PVB Film
1-EVA Interlayer Film is Less Sensitive of Moisture. And EVA
Interlayer Film can be processed in an common rood condition.
2-EVA Interlayer Film is better at mobility when melted and better for
laminating with papers, PET, silk, wire net, fabric.
3-EVA Film is good at aging resistance, the aging-resistance can be
more than 15years.
4-EVA Film is stronger in adhesive with various materials, PMMA,
PET,Metals, Plastic etc.
5-EVA glass laminating line is easier and less cost to install. PVB
glass laminating is mainly working in a big autoclave, it’s not
suitable for the company to make small quantity creatively designed
artistic laminated glass for special requirement of different
customers. PVB glass laminating machine is a large investment which
would be a barrier for the new company who are interested in
laminating glass world. Can EVA Replace PVB?
Prove 1: In China National Safety Laminated Glass Standard(2009
Edition), the Glass Lamination Ethylene-vinyl acetate EVA Interlayer
Film is recognized as a safety interlayer film for safety laminated
glass, only if the Glass Lamination Ethylene-vinyl acetate EVA
Interlayer Film past the same tests as PVB interlayer film. Prove 2: And Glass Lamination Ethylene-vinyl acetate EVA Interlayer
Film can past the tests which are required for laminated glass with
PVB interlayer film, like High Temperature Resistance Test, Radiation
Resistance Test, Humidity Resistance Test, Ball Impact Peeling Test,
Shot-bag Impact Test etc. All rights reserved by CNC-INTERLAYER TECH:
