MULTILAYER SHEET, SOLAR CELL ELEMENT SEALING MATERIAL AND SOLAR CELL MODULE

摘要

A multilayer sheet including an (A) layer containing an ethylene type zinc ionomer as a main component and a silane coupling agent, and a (B) layer containing a polyethylene-based copolymer with a melting point of 90° C. or higher as a main component and a silane coupling agent having a content ratio with respect to the resin material that is lower than a content ratio of the silane coupling agent with respect to resin material in the (A) layer, wherein the total thickness of the (A) layer and the (B) layer is from 0.1 to 2 mm. Such multilayer sheet may be superior in adhesive strength, durability and heat resistance, and obtained at a suppressed cost.
