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.

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
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
Common Applications
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.
