Material Notes:
Description: CHO-THERM® 1646 pads offer the best available thermal performance, without the use of grease, in applications where electrical isolation is not required. The low thermal impedance of CHO-THERM® 1646 materials approximates that of thermal grease. One-component CHO-THERM® 1646 pads eliminate the need for grease dispensing equipment or the labor-intensive application process. CHO-THERM® 1646 materials consist of boron nitride-filled silicone coated on one side of .002 in (.05 mm) aluminum foil. Acrylic pressure sensitive adhesive is on the other side of the foil.Information provided by Chomerics
