12.8 W/mK thermal pad for compact gaps

This 0.5 mm thick silicone pad measures 120 by 20 mm and weighs 15 g. It targets builders servicing laptops, graphics cards or small-form-factor boards where a thin, high-conductivity interface is required. The material is electrically non-conductive and non-corrosive, so it can sit directly on exposed circuitry without risk of shorts.

Fits tight spaces between die and heatsink

The pad compresses to fill uneven surfaces and microscopic air gaps that impede heat flow. Its operating range spans -40 °C to 200 °C, with a long-term rating to 400 °C, making it suitable for sustained loads on GPU memory modules or voltage-regulator zones. No curing time is needed; the natural tack holds position during assembly and allows rework if the heatsink is removed.

Single reusable pad simplifies maintenance

One 15 g piece covers the stated area without cutting multiple strips. The gray silicone resists drying out, so thermal performance remains stable across disassembly cycles. Breakdown voltage exceeds 9.8 kV at 1 mm thickness, confirming reliable insulation even under high electrical stress.

Preguntas sobre este artículo

Does the 12.8 W/mK thermal pad maintain its conductivity after long periods at high temperature?

The pad is rated for continuous operation from -40 °C up to 200 °C, with a long-term limit of 400 °C, so sustained heat will not degrade its 12.8 W/mK performance.

Will the 0.5 mm silicone pad stay cool and quiet during all-day operation?

The pad itself generates no noise or heat; it simply transfers heat between components, and its non-curing, non-toxic silicone stays stable across the full -40 °C to 200 °C range.

What thickness of gap can the 120 x 20 mm pad fill without extra material?

The pad is 0.5 mm thick and compresses to bridge uneven surfaces, so it covers gaps up to its own thickness without needing additional shims or paste.
