Hutchinson KB23G (75-mm-Roll)

Additional Product Information

Overview

The KB23G adhesive tape is a high-performance thermal insulation solution designed for both civil and military aerospace applications. Engineered from reinforced polyimide film with a pressure-sensitive adhesive protected by silicon paper, it is used to seal and protect high-temperature insulation systems on ducts, walls, tubes, and muffs. Aerospace maintenance teams rely on KB23G for its exceptional adhesion, flame resistance, and reliable performance under extreme temperature conditions.
