Creep Limit of Polymers
Creep Limit of Polymers
(OP)
I have a situation where I have a polymer that is continuously loaded and I need to look at creep. If I model it as a cantilever beam the extreme fiber stress is 441 psi. I've done some research and found that if this stress is below the "creep limit" I do not need to be concerned with creep but I'm having a tough time finding that information. First, is my approach correct by just finding the stress and making sure it is below the "creep limit"? Second, does anyone know a good place to find that information for the following:
Polypropylene, Homopolymer
Celcon M90 (Acetal, Delrin)
Nylon 66/6
I'm currently working with my vendors, etc. but I'm hoping someone out there can shed some light on the situation. Thanks!

We use a material called Torlon 4203, extruded polyamide-imide. This has very good creep properties. We use in a product that is submerged to 1000 PSI for extended periods of time.
