Thermal Gap Filler Pads

Thermal gap filler pads are designed to transfer heat away from sensitive electronic components while accommodating uneven surfaces and tolerance stack-up.

Stockwell Elastomerics fabricates custom thermal interface pads from engineered silicone elastomers formulated for efficient heat conduction and long-term reliability.

Engineered for thermal performance. Built for demanding electronics.

Why Thermal Gap Filler Pads?

Thermal gap filler materials are commonly specified when applications require effective heat transfer to a heat sink or chassis. They are conformable to fill air gaps and offer vibration dampening. While gap fillers do not rebound well, they offer long-term compression performance.

These materials help extend the service life of electronics by improving thermal management and reducing hot spots.

Custom Fabrication Capabilities

We manufacture thermal gap filler pads using various production methods including precision die cutting, waterjet cutting, and flash cutting.

Stockwell offers custom thickness and multi-layer constructions for these products.

Die cutting and fabrication of high-performance elastomers, including thermally conductive materials, are part of our core in-house capabilities.

Integrated engineering and manufacturing teams allow for fast response to design revisions and urgent production timelines.

Common Applications

Thermal gap filler pads are frequently used in power supplies and control systems, telecom and data infrastructure, EV charging equipment, renewable energy systems, medical diagnostic electronics, industrial automation, and robotics applications.

Applications often require balancing thermal conductivity, electrical insulation, compression force, and long-term material stability.
