Film EVA

Film EVA (ethylene vinyl acetate EVA film) made of elastomeric polymer material by bezavtoklavnogo, high-temperature regime.This film is made of ethylene vinyl acetate resin. Very high tensile strength, the ability to withstand high temperatures, high moisture resistance and reliability in long-term operation, makes it a very popular application in the workplace.EVA film is very high interlayer for laminated glass production. Manufacture of safety glass "triplex" and decorative glass by vacuum (safe) and bezavtoklavnogo laminating one of the major applications of EVA film.The film has a very good coupling properties of such materials as silk fabric. rice paper, sheets, PET film, polycarbonate sheet, banner and banner mesh wire.After lamination glass film EVA, it gets very good strength and insulating properties. Glass, EVA laminate film, almost entirely retards ultraviolet radiation.A very interesting application is found for the film in the production of laminated glass art. For this purpose, a special furnace EVA BM. EVA film is placed between the decorative materials. It could be fabric, and the leaves of plants, all kinds of decorative films, paper and many other materials.Compared with other materials, EVA film has the following advantages:very high quality laminated glass;miniscule percentage of defects in the finished product;high strength glass;to store film EVA, is not required, any special conditions.Among the drawbacks is worth noting the high opalescence (frosted glass), it is particularly noticeable in multilayer lamination. During the operation may cause yellowing. Laminated glass technology EVA, is not very high shear strength. This is particularly evident at low sub-zero temperatures and can lead to phase separation (delamination). Also, EVA film is sensitive to humidity.
