Laminated glass is made of two or more pieces of glass with one or more layers of interlayer films between them. A bonded composite glass product. There are variety types of interlayers, like PVB, EVA, ionoplast interlayer film (Known as SGP),etc.
Laminated glass is gaining more and more attention due to its high safety. In the field of architectural glass, it is hard to say which type of interlayer film is more popular, because they have different product characteristics, each has its own advantages.
EVA interlayer film
The full name of EVA is ethylene-vinyl acetate copolymer, which has water resistance and corrosion resistance. Compared with PVB film or ionoplast interlayer film, it has a lower melting temperature and good fluidity, it can be operate at 110℃-120℃and the finished glass transparency and adhesion strength are both qualified.
A Simple oven with vacuum and heat will meet the production needs of EVA lamination, so the investment in production equipment is small, and occupies a small area for equipment installation.
Due to the good fluidity of the EVA film, it is suitable for variety types of insert layer lamination which make decorative glass with rich patterns.
