摘要:
Disclosed is a polyamide-ionomer composition suitable for use in a backsheet in a photovoltaic module comprising a polymer component comprising a polyamide and an ionomer comprising a copolymer of ethylene, an alpha, beta-unsaturated C3-C8 carboxylic acid, wherein the carboxylic acid functionalities present are at least partially neutralized to carboxylate salts of one or more alkali metal, transition metal, or alkaline earth metal cations; 0 to 20 weight % of pigment; and 0 to 40 weight % of filler; wherein the combination of pigment and filler comprises 8 to 50 weight % of the composition; and 0 to 5 weight % of weatherability additives.
