Thermal Interface Materials

Thermal Interface Materials (TIMs) are used between a warmer surface and a cooler surface to promote heat transfers.

Applications for thermal interface materials also include batteries in electric vehicles (EVs). To avoid overheating and to help reduce the risk of fire.

We proudly work with these material partners

Converting Thermal Interface Materials

At ISP, we understand thermal interface materials (TIMs) and source them from industry leading suppliers, like Polymer Science and Henkel Adhesive Technologies. We then convert these materials into thermal gap pads, made from thermally conductive silicones and other polymers. ISP also sources and converts thermal adhesive tapes, another type of TIM.

Depending on your volumes and required tolerances, ISP can process these materials through digital knife cutting or precision die cutting technologies to transform thermal interface materials into finished products. ISP also works with customer supplied materials and can recommend the optimal converting process for your thermal management application.

The ISP Advantage

ISP is more than just a die cutter and fabricator. We provide engineering support and prototyping, with the flexibility to adapt to your specific process needs. Most importantly, we can guide your decision in choosing the right thermal interface material and in the most cost-effective quantities.

From prototyping through production, ISP can be an extension of your engineering team

Thermal Gap Pad Materials
Thermally Conductive Tape

Thermal Gap Pad Materials

Most thermal gap pad materials use thermally conductive silicone foams, cellular materials that transfer heat and provide high-temperature resistance. Normally, silicone foams are thermally insulating; however, ISP can source silicone foams with filler particles that provide thermal conductivity. For silicone-sensitive environments, ISP can convert gap pads made from other thermally conductive polymers instead.

Among their advantages, thermally conductive silicone foams keep their shape under prolonged compression. They also “bounce back” when this compressive force is removed. In addition, thermally conductive silicones retain their properties after prolonged exposure to heat. When used as thermal gap pads, these soft but solid materials can replace messy gap fillers or greases.

Key Features of Silicone-based Gap Pads

Thermal Conductivity

They transfer heat efficiently and are available in a range of TC values to meet application-specific requirements.

Softness and Conformability

They can fill gaps and uneven surfaces without damaging sensitive electronic components.

Temperature Range

They have a wide operating range, often from -50°C to +200°.

Lightweight

Foams are low-density materials that help reduce product or vehicle weight.

Electrical Insulation

Most are electrically insulating (rather than electrically conductive), which helps protect electronics from short circuits.

Variety and Customization

Thermally conductive silicone foams are available in a range of thicknesses and support die cutting or digital knife cutting and custom packaging.

Environmental Resistance

Silicones resist moisture, ozone, and chemicals.

Flame Retardant

Some grades meet flammability standards such as UL 94V0.

Common Applications

Electronics and Electrical Equipment

Battery Thermal Management

Lighting

Computer and Data Centers

Aerospace and Defense

Thermally Conductive Tape

Thermally conductive tapes can replace or reinforce metal screws, clips, or fasteners in electronic assemblies. ISP die cuts thermally conductive tapes, or thermal adhesive tapes as they are sometimes called, and can suggest materials and material manufacturers for your application..

Thermal adhesive tapes consist of a pressure-sensitive adhesive (PSA) that is applied to a backing material that distributes stress along the tape and provides reinforcement. To impart thermal conductivity, the acrylic adhesive that’s used contains specialized fillers. These TIMs are easier to apply than pastes or greases and do not require hand tools.

Key Features

Thermal Management with Adhesion

These thermal interface materials manage heat efficiently and use a structural adhesive that supports product assembly.

Easy, Clean Installation

Unlike greases or pastes, tapes are dry and easy to apply. Peel-and-stick products eliminate the need for clamping, mixing, and curing.

Mechanical Attachment

In miniaturized electronic designs, tapes are easier to apply than mechanical fasteners.

Conformability

Tapes fill air gaps between uneven surfaces and are available in a range of thicknesses.

Electrical Insulation

Most tapes are electrically insulating, which makes them ideal for isolating live components while transferring heat.

Variety and Customization

Thermal adhesive tapes support die cutting or digital knife cutting along with custom packaging.

Lightweight

Tapes weigh less than metal fasteners.

Flame Retardant

Some tapes meet flammability standards such as UL 94V0.
