Kraft TU

Cottrell Kraft TU has all the same exceptional properties of their Kraft papers with the addition of thermal upgrading chemical treatment used to improve its thermal stability, allowing it to withstand higher operating temperatures without degrading. This makes it ideal for electrical insulation in applications like transformers, motors, and cables. Cottrell’s Kraft-TU, is manufactured on a multi-ply cylinder machine, offering excellent elongation (ability to stretch without tearing) and physical strengths.

Kraft TU is available from .002″ to .125″ in rolls, sheets, or coils slit to your specifications. 

TU kraft paper is commonly used in electrical equipment where heat resistance is critical, such as in transformer windings or as insulating layers in high-voltage systems. Its enhanced thermal properties ensure durability and reliability under continuous high-temperature conditions.
