Softtherm U 105 and U 200 - Keratherm

Flexible ceramic thermal conductive and isolating films Softtherm U 105 & U 200 are especially designed for silicone sensitive applications and are alternative materials to the silicone based Softtherm films. The U 105 & U 200 films have excellent electrical isolation and a very good thermal conductivity.

Possible Thickness:
U 105: 0.5mm – 5.0mm
U 200: 0.5mm – 4.0mm
