LayTec - Model X Link - Ethylene Vinyl Acetate System (EVA) Brochure

In solar modules, the ethylene vinyl acetate (EVA) or polyolefin encapsulation protects the sensitive solar cells from the environment. In consequence the degree of intermolecular cross-linking of EVA or polyolefin is decisive for the long-term stability and performance of a module. Cross-linking is achieved by thermally curing the polymers during the lamination process.
