Tufquin TPT is a three-ply composite of TUFQUIN mineral insulation paper bonded to both sides of 25µm polyimide film with a high quality resin.
The TFT composite combines the high mechanical and dielectrical strength of polyimide film with the excellent thermal aging characteristics and resin absorption of mineral papers.
