Sil-Pad 900S Thermal Pad

NEDC has been die-cutting thermal pads since its inception in 1982. One of the more popular products Sil-Pad 900S by Henkel’s Bergquist. It is one of the most commonly die-cut materials NEDC converts. This product is part of the Sil-Pad family, featuring great thermal conductivity while being electrically isolating. This material exhibits great properties with a silicone binder that is reinforced with fiberglass to become a great solution for low pressure yet thin thermal situations. This pad matches a highly compliant and smooth surface that compliments its high thermal conductivity.

Sil-Pad 900S combination of silicone rubber & fiberglass make it great for electronic applications. For example, it has a great flame rating (UL94 V0), is non-toxic, and has a continuous temperature range of -76°F to 356°F. In addition to these properties, Sil-Pad 900S also exhibits great physical properties, such as tensile strength and elongation. The fiberglass reinforcement provides great resistance against sharp objects that may be present during the assembly process. Considering Sil-Pad 900S is electrically isolating, it is commonly used to isolate power sources from heat-sinks. Its thermal conductivity of 1.6 W/m-K, along with a low thermal impedance, make it a great solution in situations with high thermal requirements. Low clamping force such as spring clips are commonly used with Sil-Pad 900S. Sil-Pad 900S is used in power supplies, power semiconductors, automotive electronics, and motor controls.

The standard color of Sil-Pad 900S is a rugged pink. NEDC commonly die-cuts parts out of these materials in standard & custom non-standard shapes. Sil-Pad 900S is available with a thermally conductive pressure sensitive-adhesive on one side. This material is normally is provided in the thickness of .009″. Sil-Pad 900S is normally available in 12″ x 12″ sheets or roll form. Sil-Pad 900S is also known as SIL PAD TSP 1600S.  For more information on Sil-Pad 900S, or if you believe you have an application that could utilize it, please contact
