3M 5516 Technical Data

3M™Hyper Soft Thermally Conductive Interface Pads
5516 / 5516S

Product Description

3M™ Hyper Soft Thermally Conductive Interface Pads 5516 / 5516S are designed to provide a preferential heat transfer

path between heat generating components and heat sinks, heat spreaders or other cooling devices. These products consist

of a highly conformable slightly tacky silicone elastomer sheet filled with thermally conductive ceramic particles which

provide special features listed as follows.

• Good thermal conductivity and good electrical insulation properties.

• Good softness and conformability even to non-flat surfaces.

• Softness results in low stress on board components.

• “S” version incorporates a thin PEN (polyethylene-naphthalate) film carrier for improved handling and a non-

tacky surface for ease of rework.

• Slight tack allows pre-assembly. Good wettability for better thermal conductivity.
