Sil-Pad 2000, 10mil die-cut

Sil-Pad 2000, 10mil die-cut

NEDC has an affinity for an incredible amount of thermal management materials. TIMs, as they are called, have started to replace messy thermal greases & mica in some applications as electronics have become ubiquitous. One of the most popular thermal pads that NEDC converts through die-cutting is Sil-Pad 2000. The reason for its popularity is obvious. It becomes readily apparent after a review of the properties and characteristics of the material.

What is Sil-Pad 2000 (SIL PAD TSP 3500)?

Sil-Pad 2000 is a silicone elastomer reinforced with fiberglass insert that is filled with thermally conductive fillers. This yields a thermal pad that is quite impressive in its different properties. This pad features a 90 Shore A durometer, and a thermal conductivity of 3.5 W/m-K.* As of this writing, it has the highest thermal conductivity value in the Sil-Pad family. Despite its high thermal conductivity, it is still a high reliability insulator that features a high volume resistivity of 1011 Ohms. As with most Bergquist thermal pads, this material features the arduous UL 94 V-O rating. In addition, this material has a impressive continuous usage temperature of -76° to 392°F. This material also comes in a clean, and neat white color. Given Sil-Pad 2000s high performance, it is found in a number of demanding applications ranging from avionics to high-performance power supplies.

Sil-Pad 2000 vs Sil-Pad A2000? Are they the same?

I was going to write a blog on this, but I thought it would be better to have a note in here. A lot of times customers confuse Sil-Pad 2000 with Sil-Pad A2000. They are different materials. One may ask, what are the differences? 

-The Outgassing with Sil-Pad A2000 on the TML(Total Mass Loss is slightly higher

-Sil-Pad A2000 is available only .015” and .020”, while Sil-Pad 2000 is available slightly thinner at .010”.

-Thermal Conductivity to better with Sil-Pad 2000, but only slightly.. 

-Dielectric Constant is slightly better for Sil-Pad A2000

-The thermal performance and thermal impedence are essentially neck, and neck with Sil-Pad 2000 being slightly better.

Well its always a good idea to test in the application, Sil-Pad A2000 can be considered a good alternative to Sil-Pad 2000 for thermal applications.

Availability

Sil-Pad 2000 aka SIL PAD TSP 3500 can be provided with pressure-sensitive adhesive, on one side or both. This adhesive is an unloaded acrylic tape(AC). This adhesive aids in assembly by peel and sticking parts. NEDC commonly die-cuts or waterjet cuts these materials into special custom or generic shapes for its customers.
