Dielectric properties of our plastics become very relevant when it comes to applications in the high frequency domain, such as 5G communication. This tool offers you insights into both the dielectric constant and the dissipation factor as function of temperature and frequency.
The model is based on physical experiments covering a wide range of temperatures and frequencies:
At the certain frequency ranges (1MHz to 1GHz, 10GHz to 100GHz) and at various temperatures, there is lack of practicable measurement methods. Thus the dielectric properties are deduced from physics modelling and existing data. By fitting the Havriliak–Negami equations, the dielectric data can be predicted for a wider frequency range (0.1Hz to 100GHz).

Why can't I select all Envalior grades?
We're in the process of expanding this tool to more grades, but this depends on the availability of experimental data as well as on the demand for that particular grade. Let us know what grades you're looking for by filling in the feedback form on the bottom right of the page!
Why am I not allowed to export the data from the graph?
