3M 5515S-20 Gray Thermally Conductive Silicone Interface Pad

5515S-20

3M™ Thermally Conductive Silicone Interface Pad 5515S is the same as 3M™ Thermally Conductive Interface Silicone Pad 5515, but with a thin 13 µm polyimide film laminated onto it to help enhance the electrical insulation performance, anti-abrasion and ease of handling and die-cutting. The main function of this product is to help provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices.

Good thermal conductivity (2.7 W/m-K)
Hardness: Shore 00 = 90
Good dielectric properties

Color: Light Gray with Yellow

Liner Material: Unwind Side: Film, Liner Side: Film

Backing/Carrier Material: Silicone Elastomeric Sheet Filled w/ Conductive Ceramic Particles w/ a Thin Polyimide Film Carrier

TotalThickness: 0.20 mm
