Electro casting resins are decisive in the further development of numerous industrial sectors. Whether in the automotive, electronics, energy or household industries, they are all heavily dependent on progress in the storage and transport of electrical energy.

The encapsulation of sensitive electronic components with electro casting resins from RAMPF Polymer Solutions protects them reliably and efficiently against chemical substances and environmental influences such as heat, cold and wetness - which increases performance. One requirement in particular is becoming increasingly important for electro casting resins: the thermal conductivity.

Increasing importance of thermal conductivity

In general, thermal conductivity is a measure of the material property of transporting thermal energy in the form of heat. The velocity with which heat flows through a material determines its thermal conductivity. We give the thermal conductivity in the unit W/m*K (watts per meter and Kelvin). 

But why is the significance of thermal conductivity increasing?

There is one main reason for this: components of electronic components are becoming smaller and smaller. This is associated with an increase in power density. In order to guarantee efficient heat dissipation with low thermal load at the same time, a correspondingly high thermal conductivity of the electro casting resin is required.

Due to their outstanding thermal conductivity, resin systems from RAMPF Polymer Solutions ensure both the efficient dissipation of heat from the components and the maintenance of the required mechanical flexibility. This enables the reliable implementation of innovative solutions for power electronic components.

As the thermal conductivity of electrical casting resins increases, so does their viscosity. The more viscous an electro casting resin is, the stronger its particles are bound to each other and therefore less mobile. As a result, electro casting resins with a high viscosity transport heat better and thus dissipate it faster.
