EVA COMPOSITE SHEET FOR SOLAR MODULE

摘要

PURPOSE: An EVA composite sheet for a photovoltaic module is provided to improve the stability of a cell in a photovoltaic module manufacturing process by maintaining stable shrinkage against heat or pressure which is created in a lamination process of the photovoltaic module. CONSTITUTION: A base material layer(10) is composed of ethylene vinyl acetate. The MI(Melt Index) of the ethylene vinyl acetate is from 15 to 50. The base material layer is formed into the thickness of 2.1mm to 2.85. A stiffening layer(20) is formed into thickness of 0.15mm to 0.9 in both sides of the base material layer. The stiffening layer protects the base material layer from heat or pressure created in a lamination process.
