Design Properties for Engineers: UL RTI vs HDT of Commodity, Engineering and High Performance Polymers

In this blog post, we compare the long-term thermal properties (based on UL RTI 746B) to the short-term properties (based on the Heat Deflection Temperature, HDT @ 1.8 MPa).

The figure below shows the comparison of the long-term and short-term thermal data. This allows designers to immediately assess the suitability of a selected polymer in terms of continuous heat exposure as well as short-term heat impact. Furthermore, alternative polymers can be selected too.

I made a YT video which shades light into this topic in more detail:
