Softtherm 86/300, 86/320 - MH&W Thermal Products

Softtherm 86/225 and 86/320Single layer Softtherm films with graded thermal behavior. These films are partial fiberglass reinforced and are a low cost alternative to the two layer Softtherm films. 86/300 is fiberglass reinforced up to a thickness of 1.0mm and 86/320 up to 1.5mm.

86/300 is optionally available with an one-sided adhesive as 86/300K.

Possible Thickness:
86/300: 0.5mm – 5.0mm
86/320: 1.0mm – 5.0mm
