Product Description

Located in Dongying, Shandong ,China, Shandong Wanda Micro-electronics Company 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 Microelectronic Company Ltd is 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 PI film prodction enterprises. Products are widely used in flexible printed circuit board, LED, power batteries and other field. 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 film (BOPI), the main specifications include 12.5μm, 25μm,50μm. The width is within 1100mm. In addition to the high insulation and high and low temperature resistance (-273°C-300°C) of traditional PI, Our product also have the characteristics of low CTE, high support and high flatness. Prodcts are widely used in LED lighting, flexible circuit board, power batteries and other fields.
