Stress-strain behavior is at the core of any application development. This tool predicts the stress-strain curve of our grades for any given temperature and humidity. Always the right conditions for your application!

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?

Why can't I select conditioned samples at high temperatures?
All conditioned samples (50% or 80% relative humidity) were conditioned at room temperature. Because heat transfer is much faster compared to moisture diffusion, it's possible to heat the conditioned samples to testing temperature, while maintaining the equilibrium moisture content inside the sample. Experience shows that this is still valid above 100°C (212°F). However, the higher the temperature, the more pronounced is the drying at the surface of the samples. We have seen that above 140°C (284°F), this starts to affect the measurement results. Therefore, we don't provide predictions for conditioned samples above that temperature.
