TIC800M — Product overview
TIC800M is a metal phase change thermal interface material (bismuth alloy) developed by mixing multiple metals to solve high-power heat dissipation problems and improve application reliability. The material delivers very high thermal conductivity (18.9 W/m·K), is not easily volatile, is safe and non-toxic, and has stable physical and chemical properties. When the temperature rises above its phase transition temperature (>60°C), the metal foil softens and undergoes phase transition, tightly filling the small irregular contact surfaces on the device to form a low contact thermal resistance interface — significantly outperforming polymer-based PCMs and greases on raw thermal conductivity.
