Black polyimide film
Black Polyimide Film is made from special formulation and work process with black color, widely used in manufacturing black coverlay,label,etc. for flexible circuit board, and other fields.
Characters:
* In black color (both matte and polish black available)
* Class H insulation and can work for long term under 200℃.
*Higher mechanical strength, better tear resistance and flexibility.
*Good dielectric strength, and excellent radiation and chemical resistance
*Supplied with different width and thickness(0.0125mm--0.20mm)
