Laminated Glass with SGP Film

Laminated Glass with SGP Film

DuPont™ SentryGlas® Plus (SGP) interlayers help create safety glass that protects against bigger storms, larger impacts and more powerful blasts. They become an engineered component within the glass, holding more weight, so the glass can serve as a more active structural element in the building envelope. And they do all this while increasing framing system design freedom and improving long-term weather resistance.SGP laminated glass is a kind of strength greater laminated glass, stronger than conventional laminated materials , it is also called structural laminated glass.
SGP interlayers:
SentryGlas plus with high penetrability safety  is the latest product of Dupont laminated glass, it makes the invention of laminated glass beyond the existing technical performance. Continue reading “Laminated Glass with SGP Film”

Laminated Glass with PVB Film

Laminated Glass with PVB Film
sponsored by  northglass sunny glass
Laminated glass is processed with special technology under high temperature and high pressure by adding one or more layers of Polyvinyl Butyral (PVB) with tough and strong binding between or among two or more glass layers. For the great binding performance, laminated glass could stop external force attack and the chips will be bind with PVB after breakage to avoid making harm to person. And even the glass could still resist attack from wind and rain in breakage status.
PVB Film Description:
PVB film is  a macromolecule material molded by polyvinyl butyral resin that is plastificated and extruded by plasticity DHA.PVB film, with the excellent light transparent performance, heat resisting and cold-resisting, elasticity, is well-sticking to inorganic glass and becoming the best gluey material in the world of making laminated safety glass at present.
PVB film is the semitransparent membrane,with no impurity,flexibility and smooth surface.Though there is certain roughness,it has well intensity of stretch proofing and extension at break. Continue reading “Laminated Glass with PVB Film”

Laminated Glass with EVA Film

Laminated Glass w/t EVA Film Laminated glass with EVA film is much important  one in the series of laminated glass.The processing principle of EVA laminated glass is  similar to most of the laminated glass . Specifically , using EVA film to laminating glass does not require pre-heating, pre-pressure and autoclave. All laminating processing will be finished and completed in one vacuum laminator.  EVA  film for glass have nice transparency, outstanding adhesion and aging-resistance,can be used for architectural glass.

EVA film:

EVA film is made out of macromolecule material and it performs excellent in bonding strength, heat resistance, cold resistance, humidity resistance and tensile strength in laminated. It has been partly taking the places of PVB film in laminated safety glass, laminated art glass, laminated color glass.

Advantages of EVA film :

– high tensile strength         – excellent transparency                   – outstanding adhesion

– UV protection                     – high wind resistance                       – good temperature withstanding

– water proof                        – humidity durable                   – long-term reliable                  – sound barrier

EVA film for safety glass:
  1. Extremely high transparency .The transmittance rate can reach 92.1%.
  2. Outstanding heat, humidity and ultraviolet ray durability and long-tem reliability
  3. Superior low moisture ingression than PVB,can fit for side-naked processing in high humidity environment.
  4. Widely use in more fields than other internal EVA films, which only lamiante silk and films with glass.
  5. Highest interlayer laminating strength and security characteristics, can avoid ungluing and air bubble caused by low-quality film.
  6. Superb compatibility with polymers and other insert media, such as PET,PC ,PVC,glass,wood cloth,paper,liquid crystal sheet, solarcell,etc
  7. Easy handling, using low-cost small vacuum-kiln equipment.
  8. Highest productivity, low waste.

In the processing of EVA laminated glass,owing the ordinary glass with its green color,it will  influence the original design effect.  However, using  ultra-clear glass can have a excellent performace, it can make the interlayer fabric more  clearly.

EVA film: EVA interlayer film

EVA stands for ethylene vinyl acetate, a copolymer resin used in the production of laminated glass as the interlayer sandwiched between two pieces of glass. The main function of the interlayer is to hold the two piece of glass together, thus making them safer and more secure. EVA film is translucent and has a light pattern on the surface before heating.

After heating, it becomes completely transparent, offering good visibility. In the production of laminated glass with EVA interlayer, no autoclave, roller press, air bag, or vacuum rubber ring is required. As EVA interlayer can be handled under normal climatic conditions, no clean room with climatic control is required.



1. About Us:

China New Concept Glass Materials Co., Ltd. ( ) is focusing on the research and development (R&D) and producing EVA FILM interlayer for Laminated Glass. CNC GLASS has built a great technical team to study modifying the property of EVA FILM. High quality is the most important core of our compatibility. Our final goal is to be the provider of NEW CONCEPT of EVA FILM for Laminated Glass to create a NEW CONCEPT living environment for our customers.

2. Features of Our Products

1.) Clean and smooth, having no black dots, can be stored for a long time without becoming yellow.

2.) Our films are ultra-transparent .

3.) Great conglutination. The film are becoming adhesive at the temperature about 100 degrees.

4.) Improved by eliminating static and tension of the films to forbid the glass self-bursting.

5.) Our films reduce the leaking glue during the laminated processing.

6.) Our films have past the tests of “High Temperature Resistance, Humidity Resistance, Radiation Resistance, Ball Impact Peeling Test and Shot Bag Impact Test”.

3. Processing Procedure Notes

1.)  Activate vacuum pump for 2-3min till the vacuum value reach 0.095Mpa, then start heating.

2.)The temperatures and times for processing based on 1Pc 5mm Glass +1Layer EVA Film + 1Pc 5mm Glass

3.)For thicker glass or more layers of EVA Film, the heat-holding-time should be longer, please check with “The Processing Parameter of Different Glass Thickness and EVA Film Layers” or consult us.
