Abstract
Official abstract text for this publication.
Disclosed are multilayer structures comprising polyamide-ionomer compositions suitable for use in a backsheet in a photovoltaic module comprising a polymer component comprising a polyamide and an ionomer; 0 to 20 weight % of pigment; and 0 to 40 weight % of filler; preferably wherein the combination of pigment and filler comprises 8 to 50 weight % of the composition; and 0 to 5 weight % of weatherability additives.
First claim
Opening claim text (preview).
What is claimed is: 1 . A multilayer structure suitable for use as the backsheet in a photovoltaic module, the structure comprising at least one layer comprising a polyamide-ionomer blend composition comprising (i) a polymer component comprising 1) 53 to 64 weight %, based on the combination of (1) and (2), of polyamide; 2) 36 to 47 weight %, based on the combination of (1) and (2), of an ionomer comprising a copolymer of copolymerized units of (a) ethylene; (b) from 2 we…
