Quality Control of EVAFORCE® SUPER CLEAR INTERLAYER FILM
Testing Adhesive Strength Properties of Laminated Glass with EVAFORCE SUPER CLEAR INTERLAYER FILM
Testing Humidity Reststance Properties of Laminated Glass with EVAFORCE SUPER CLEAR INTERLAYER FILM
Placing the laminated glass with EVA FILM samples vertically inside the climatic chamber and maintaining them for two weeks at a temperature of 50 degrees and 95% relative humidity. Water condensation on the surface of the laminated glass samples is allowed.
No bubbles or opaqueness are noted in the spacer in any of the laminated glass samples tested.
Testing UV Radiation Resistance Properties of Laminated Glass with EVAFORCE SUPER CLEAR INTERLAYER FILM
Make the laminated glass with EVA FILM subjecting to 2000 hours of radiation. The samples of laminated glass with EVA Film are placed at a distance of 1,100mm from 16 ULTRAVITALUX lamps which was form a 1m*1m field. The temperature is maintained at 45℃ (5℃ tolerance )and the humidity is 50%.
To measure the durability, the luminous transmission has been measured by the wavelength between 380nm and 780nm before 2,000 hours of exposure to the ULTRAVITALUX lamps.
A minimum 3 transmission measurements have been taken from each laminated glass sample and the average has been calculated from these data.
In the end, compare the differences of Light Transmittance and check the presence of any faults(bubbles, opaqueness, degumming etc)

Application of EVAFORCE® SUPER CLEAR INTERLAYER FILM
Ethylene-vinyl acetate EVA Interlayer Film for Laminated Glass
EVA 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 stick the two piece of glass together, in order to make the sandwiched glass safer and more secure.
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 glass. It has been partly taking the places of PVB film in laminated safety glass, laminated art glass, laminated color glass.
EVA film is not adhesive before heating. After heating, it melts and reacts. 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 processed under normal climatic conditions, no clean room with climatic control is required. And the producing machine of laminated glass with EVA Film is less cost and easier to process.
Laminated Glass with EVA Film
Laminated Glass with EVA Film is an important kind of laminated glass in glass industry .The processing principle of EVA laminated glass is similar to most of the laminated glass . Furthermore, using EVA film to laminating glass does not require autoclave. All laminating processing will be finished and completed in one vacuum laminator. EVA Film for laminated glass has excellent transparency, outstanding adhesion and aging-resistance (more than 15 years), can be used for architectural glass, decorative glass with fabric, privacy glass, auto glass etc.
Advantages of EVA film :
– High tensile strength
– Excellent transparency
– Outstanding adhesion
– UV protection
– High impact resistance
– Good temperature withstanding
– Water proof
– Humidity durable
– Long-term reliable (long-term aging resistance)
– Sound barrier
