业内专家通过进行拉伸测试后发现,使用均匀的弹性体基片容易在金属薄膜上造成微裂痕,这最终会破坏到传导系统。但是如果使用聚氨酯泡沫胶基片,这些裂痕只会出现在气泡上,而在气泡中间的金属薄膜则不会受到损害,导电系统也就完好无损。近日,一篇关于聚氨酯泡沫的论文引起了人们的关 Tensile testing conducted by industry experts found that the use of a uniform elastomeric substrate tends to cause micro-cracks in the metal film, which can ultimately destroy the conductive system. However, if a polyurethane foam substrate is used, these cracks will only appear in the bubble, while the metal film in the middle of the bubble will not be damaged, and the conductive system will be intact. Recently, a paper on polyurethane foam aroused people’s concern
