I am in the process of testing a new air blower. The impeller is injection molded with glass filled Ultem. After about 10 hours of testing with air temperature around 65C there is a noticeable increase in the material brittleness.
Do you think these low temperature could increase brittleness in Ultem? I plan on doing some additional testing but I'm curious if there is any experience or advice out there with Ultem brittleness and heat cycling.
Thanks.
