3M 5590H-10 Thermally Conductive Acrylic Interface Pad

5590H-10

3M™ Thermally Conductive Acrylic Interface Pad 5590H is a moderately conformable and medium-soft pad with high thermal conductivity of 2.8 W/m-K (3M test method). This pad consists of a slightly tacky acrylic elastomeric sheet filled with thermally conductive ceramic particles. It is designed to transfer heat from heat generating components to heat sinks and cooling devices, improving device reliability and extending the component's life.

Non-silicone acrylic elastomer
Good softness and conformability to non-flat surfaces
Excellent compressive stress relaxation

Color: White / Gray

Liner Material: PET Film

Backing/Carrier Material: Acrylic Elastomer Sheet Filled w/ Thermally Conductive Ceramic Filler

TotalThickness: 1.0 mm
