High quality encapsulation film
Quality is ever important in our industry and now
Breyer have come up with a high quality, high speed extrusion process which has already been tested by TÜV Rheinland Germany….
BREYER’s extrusion system “CellProtect” allows the production of low shrinkage EVA encapsulation film at high production speed. Most importantly, there is no interlayer film and there is no energy consuming anealing process, which means the production is economic in terms of both cost and energy. Furthermore, Polyolefin encapsulants can be processed using the same method.
Encapsulation film produced on regular extrusion lines has a natural shrinkage which affects not only the laminating process but can result in destroyed wafers and therefore creating waste and thus increased production costs.
A high quality and low-shrinkage film allows a smooth and fast laminating process. The more shrinkage a film has the more carefully the warm up procedure must be controlled and could increase the laminating time.
Since the regular extrusion systems, using calendars or cast rolls, are limited to a certain speed/output, BREYER has developed a profitable system for the production of EVA film and other gluey materials. For the first time, using BEYER CellProtect, it’s possible to extrude EVA or Polyolefine films film at high speed by keeping the shrinkage low. The process avoids tension in the film right from the start. Post annealing systems are therefore not required. In this way the line also consumes less energy.
EVA film makers can have higher profitability by using the new technology since the output is much higher. For the module manufacturers’ using such low tension film means that their laminators
are more stable and also run as fast as possible.
