CHT Group QSil 244 45 Shore A, Thermally Conductive, Industrial Silicone Elastomer
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Product Description: QSil 244 is a 100% silicone solids elastomer designed for industrial applications where good thermal conductivity is required. These applications include rollers, electronic potting applications, thermal interface materials (TIM) and thermally conductive coatings. This two-component system offers a hard, thermally conductive, low modulus material that is readily repairable. Key Features: 100% solids, no solvents Excellent thermal conductivity Heat cure required Formerly Amber Chemical Co (ACC Silicones), aquired by CHT in 2017
