TIR®700-35 Series Carbon Fiber Thermal Pad
TIR®700-35 Series is a high-efficiency carbon fiber thermal pad that combines high thermal conductivity carbon fiber with polymer silicone material. Using advanced technology, the carbon fibers are vertically aligned to achieve excellent heat transfer performance, effectively reducing interface thermal resistance and improving cooling efficiency. It features ultra-thin, lightweight design and mechanical flexibility, making it suitable for applications that require high heat dissipation while demanding good mechanical strength of the material.

What is a carbon fiber thermal pad?
A carbon fiber thermal pad is a thermal interface material (TIM) in which high-conductivity carbon fibers are vertically embedded in a silicone matrix. Unlike conventional silicone-based gap pads, the aligned fibers channel heat directly through the thickness, delivering much higher through-plane conductivity (up to 35 W/m·K here) at lower bond lines.
Is TIR® 700-35 electrically insulating?
No. This product is **electrically conductive**. The carbon fibers make it thermally super-conductive but also electrically conductive, so it must not be placed between points that require electrical isolation. If your design needs both thermal and electrical insulation, ask us about our silicone/ceramic insulating TIM series instead.
What is the difference between a carbon fiber pad and a standard silicone thermal pad?
Standard silicone gap pads usually reach 1–16 W/m·K and are electrically insulating. Carbon fiber pads reach far higher conductivity (35 W/m·K) at thinner bond lines, but are conductive and generally denser (2.8 g/cm³) and stiffer. Choose carbon fiber when maximum heat extraction at a thin gap is the priority and no isolation is needed.
What thicknesses are available?
Standard thickness ranges from 0.30 mm (0.012") to 5.00 mm (0.200"), in the standard sheet size of 5" × 6" (127 × 152.4 mm). Custom thicknesses, die-cut shapes and forms are available on request.
