Parker Chomerics THERM-A-GAP™ A574 Highly Conformable, Thermally Conductive Gap Filler
Categories: Ceramic; Polymer; Thermoset; Silicone

Material Notes: Composition: Ceramic-Filled-Silicone Elastomer on 5 mil Aluminum Carrier

Description: The 574 Series materials provide superior thermal performance and are softer than the other THERM-A-GAP materials. Their flexible, elastic nature allows them to blanket highly uneven surfaces, drawing away and transferring heat from components such as microprocessors, video chips and power devices. A574 material consists of an extremely soft silicone elastomer loaded with ceramic particles, coated onto a 5-mil (.127 mm) aluminum carrier.

Product Attributes: High thermal performance; Softest materials and Flat sheets
