Product Description
Located in Dongying, Shandong ,China, Shandong Wanda Micro-electronics Material Co., Ltd, is a subsidiary of China Wanda Group (TOP 500 enterprises of China and TOP 100 private enterprises of Shandong) specialized in manufacturing polyimide films. Shandong Wanda Micro-electronics Material Co., Ltd founded in 2003 has 7 bi-directional stretching production lines with annual sales of more than 150 million yuan. The company now has the largest China production capacity and market share of the highest grade polyimide film (PI film) production enterprises.We passed certification of ISO9001, ISO14001, ISO45001. Our goal is constantly striving to meet customer needs.
The main products of the company are bidirectional stretch polyimide film (BOPI), the main specifications include 12.5μm, 25μm,50μm. The width is within 1100mm. In addition to the high insulation as well as high and low temperature resistance (-273°C-300°C) of traditional polyimide film (PI film), Our product also have the characteristics of low CTE, high support and high flatness. Products are widely used in LED lighting, flexible circuit board, power batteries, tape and other fields.
