THB 100 – Epoxy – Thermal conductivity
Thermoset plastic materials – Thermal Conductivity
Epoxy-based materials such as epoxy-resins have various applications, for example as coatings, adhesives and composite materials. They are for example used for industrial tooling, electronics and in the sports or automotive industry.
Epoxies have a good adhesion, heat and chemical resistance, have good mechanical properties and are also electrical insulating. These properties can be easily modified by additives, so that they can also offer a high thermal insulation or a good electrical conductivity. As they are used frequently in construction, their thermal conductivity is of interest in many application fields.
The thermal conductivity of a cured epoxy sample was measured by THB-100 (new model THB Basic, Advance, Ultimate) at room temperature and 50 °C. Therefore, the sample was placed together with the sensor (sandwich-setup) in a furnace. The thermal conductivity increases from 0.196 W/mK at room temperature to 0.204 W/mK at 50 °C, which is a typical range for hard polymers.
