What makes Coreva's Eva different?

Coreva's glass interlayers are engineered to contain peroxide curing agent having sufficient thermal stability to allow the Eva glass interlayer to flow during the early stages of the lamination cycle, wetting out the substrate surfaces and subsequently undergoing cross linking or curing prior to removing from your equipment. Cross linking or curing is the process for converting the thermoplastic Eva into a thermoset Eva that no longer softens or flows upon heat.

The curing process of Eva interlayers result from a hydrogen abstraction reaction. At the elevated temperatures of lamination, the peroxide curing agent thermally cleaves to yield two oxy radicals. The oxy radicals are very reactive and abstract hydrogen atoms from Eva's polymer radicals then combine to form crosslink, commonly referred to as cure.

PEVA / EVA Film

EVA and PEVA are the same thing. EVA is short for "ethylene vinyl acetate". Somehow "polyethylene" got added as a prefix to create the acronym PEVA. Both are words for the same copolymer. PEVA / EVA is a copolymer comprised of the monomers Ethylene C2H4 and Vinyl Acetate Monomer CH2=CHOOCCH3 conjoined to make the copolymer Ethylene Vinyl Acetate, or EVA for short.

Optically clear safety glass

We have engineered and formulated a superior Eva film that is optically clear and strengths comparable to PVB films.
