A masterpiece of ongoing research and development
evguard® laminating film is an ethylene-vinyl-acetate (EVA) based thermoset interlayer for the manufacturing of laminated safety glass. Through processing, it forms a highly cross-linked three-dimensional composite interlayer that provides the strength for laminated safety, security and architectural glass.

evguard® laminating film is purposefully designed (and fully certified) for numerous glass building facades and extreme heavy impact applications worldwide, including external facades, overhead glazing and balustrades. It has passed all stringent standards to ensure long term stability and durability in these areas.

Folienwerk Wolfen also provides evguard® MPE, a „Modified Co-Polyester“, that brings significant improvement in terms of strength, stability, durability, shear modulus and printability. evguard® MPE is a special high performance multi-layer polyester film for heavy impacts and printed laminated safety glass applications.

More details ...

With its outstanding properties and performances, amongst only few others, evguard® is a high-end, premium quality laminating film for the glass industry – fully certified worldwide.

It has been tested to to the toughest conditions, far beyond the standard certification.

evguard® laminating film already fulfills the highest classification 1 (B) 1 of the pendulum impact test DIN EN 12600:2002 (DEKRA/Certificate No.201330010) with a composite structure of FL 44.1 (float glass, 2x 4.0mm (+/- 0.2mm) with a layer of evguard® laminating film, thickness 0.38mm).

evguard® passes DIN EN ISO 12543-4 for behaviour at high temperature (Bake Test/ IFT Rosenheim). To investigate the behaviour of glass laminates at temperatures beyond the international standard test DIN EN ISO 12543-4, further tests were carried out. To prove the behaviour of laminated glasses with evguard® laminating film, laminated glass samples were exposed stepwise up to a temperature of 240°C. The glass laminates passed the test up to at least 200°C without any delamination effects or visual changes. Also at a temperature of 240°C, no delamination was detected, only a slight yellowing was observed.

In accordance with the norm DIN EN ISO 12543-4, the artificial aging by UV irradiation was carried out by means of a xenon-arc solar simulation spectrum with a power of 50 W / m² in total UV wavelength. The examined samples have been continuously irradiated for 3,000 hours. In this case, a control    measurement of the haze values and the light transmission was carried out for every 500 h. The artificial aging by UV radiation was carried out by Friedmann & Kirchner testing institute (Germany) on laminated glass samples made from a series of different laminates. Both the LSG made with evguard® laminating film and evguard® laminating film + evguard® MPE passed the test successfully. No visual change of the quality of the laminate was observed.

evguard® passes GOST Standard 30826/32996-2014 at minus 70 deg C.

evguard® passes continuous salt spray for 3,000 hours in a salt spray test according to ASTM B117/ISO 9227.

In the test chamber of the salt spray cabinet, which is heated to 35 ± 1°C, a solution of 5 ± 1 percent by mass of sodium chloride with a pH 6.5 – 7.2 is atomized continuously. As a result of spraying this solution, the relative humidity in the test cabinet is more than 95 %. In time, all panels show more or less iridizing colors due to the aggressive attack of salt spray on the top coating on the glass. None of the samples show delamination.

evguard® laminating film provides low deflection and high shear modulus. Thus, for architectural calculations, overall laminate thicknesses can be reduced significantly resulting in savings. evguard® laminating film offers safety properties in a broad temperature range, not only at room temperature but also at temperatures above 50 °C. These properties bring new possibilities in open edge applications since there is no need for frames anymore.

evguard® laminating film is less sensitive to moisture compared to other interlayer films like ionomers or PVB. This offers a great advantage in resistance of the laminate against weathering conditions and durability of the final product. evguard® laminating film is suitable for open edge applications and does not require a strict moisture control during transportation, storage and use. (DIN EN ISO 62)

Sound insulation glass made with evguard® laminating film with a 44.2 construction achieves a sound insulation rate of at least 37 dB without additional sound insulating layers. (ISO 10140-2/MFPA Leipzig)

Because the glass layers form a solid composite once they are laminated with evguard® laminating film, and evguard® nonetheless remains highly elastic, this type of laminated glass is ideally suited for use as protection from break-ins or falls, or even for much stronger loads by adding our evguard® MPE - Special high performance multi-layer polyester insert for heavy impact and printed laminated safety glass applications. With the 55.4.MPE(800) construction it passes Florida Building code TAS 201-94 (Large Missile) and TAS 203-94@ ±120 psf (Cycling).
