Ethyl vinyl acetate

with ethyl vinyl acetate (abbreviation EVAC) is designated a group by copolymers. Other ways of writing, designations and/or abbreviations are ethyls/vinyl acetate, ethyl vinyl acetate, EH, E/VA and ethyl vinyl acetate and/or. PEVA (polyethylene vinyl acetate).

chemical and physical characteristics

EH is available as granulates, aqueous dispersion in addition, as foil material. For a plastic it has a high heat resistance and a good resistance to aging.


use

from ethyl vinyl acetate copolymers most diverse products are manufactured: Welding foils (office supplies, solar modules), soles, Duschvorhänge, floor coverings, electrical cable. Also one makes fusion adhesives of these polymers.

With very high-quality Tuft carpet or needle bonded fabrics - materials EH serves dispersions for the fiber integration.

In the Photovoltaik solar cells are embedded in EH. Here the EH used in foils becomes at temperatures over approx. 150 °C melted, highly transparent and interlaced three-dimensional. After the cooling such a durable group is present, which protects the cells against environmental influences.
