Cho-Therm® thermal insulators

HITEK offers the Chomerics range of Cho-Therm® thermal insulators. In that range there are several materials that offer themselves for general use.

Cho-Therm® 1674, Chomerics’ original thermal interface pad, CHO-THERM® 1674 provides good thermal performance at economical prices. 1674 material is a low-cost, aluminium oxide-filled silicone elastomer designed for applications, which require good heat transfer performance and moderate electrical isolation characteristics.

CHO-THERM® 1678 material is Chomerics lowest cost boron nitride-filled thermally conductive insulator. 1678 material is reinforced with fibreglass cloth to provide maximum resistance to tear, cut-through and punctures due to burrs and other mating surface irregularities.

CHO-THERM® T500 material is a highly thermally conductive interface insulator designed for use where the lowest possible thermal impedance is required. Fibreglass reinforced CHO-THERM® T500 insulators combine a silicone binder with a boron nitride filler to deliver thermal impedance of 0.19 C-in2/watt.

There are other materials in the CHO-THERM® range that offer other features. These can be found on the Thermal selector chart. If you have an application that you think requires one of the other materials please contact HITEK Electronic Materials Ltd
