Low shrinkage amber polyimide film owns general properties of typical polyimide film, besides, it has better dimension stability, widely used in FCCL laminating.
Good stable dimension
Low shrinkage rate
Available thickness: 25um 50um 75um
Brief introduction of polyimide film
The preparation method of the film is that: the polyamic acid solution is cast into a film, and after the stretching, the film is imidized at a high temperature. The film is yellow and transparent, a prominent high temperature, radiation resistance, chemical resistance and electrical insulation properties, long-term use in the air 280℃ or so.
Technical requirements for polyimide film
1. appearance: smooth surface , no particles, bubbles and pinholes and impurity defects, edge neatly.
2. width is 520mm, some can reach 1040mm, splitting is available
3. thickness tolerance ≦±10%
