ETHYLENE-VINYL ACETATE COPOLYMER SHEET, METHOD FOR PRODUCING THE SHEET, LAMINATED GLASS USING THE SHEET, AND SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide an EVA sheet which is improved in transparency and excellent in productivity when the sheet is produced and in handleability when the sheet is used.;SOLUTION: An ethylene-vinyl acetate copolymer layer made of a composition containing an ethylene-vinyl acetate copolymer as a main component is an ethylene-vinyl acetate copolymer sheet having a structure in which at least three layers are laminated. The vinyl acetate content of an ethylene-vinyl acetate copolymer layer 6 (inside ethylene-vinyl acetate copolymer layer) held by at least two ethylene-vinyl acetate copolymer layers (outside ethylene-vinyl acetate copolymer layers) 7A and 7B is higher than the vinyl acetate content of the outside ethylene-vinyl acetate copolymer layers 7A and 7B.;COPYRIGHT: (C)2011,JPO&INPIT
