The 3M Thermally Conductive Silicone Interface Pads are designed to transfer heat from hot components to cooler surfaces. They offer excellent conformability, gap‑filling capability, and environmental durability, with thermal performance up to 150 °C. Some versions include a PET permanent film on one side, giving a non‑tacky surface that eases rework and improves dielectric strength.
A selection guide lists the various part numbers (5516, 5516S, 5519, 5519S, 5591S, 5592, 5592S, 5595, 5595S) together with key specifications such as thermal conductivity, Shore hardness, thickness options, and operating temperature limits. The document also contains warranty, liability, and contact information for 3M Electronics Markets Materials Division.
