Delrin 111P NC010 fatigue curve

[scandroglio]

Hello to all forum, there is someone that can give me or said where find the fatigue curve about Delrin 111P NC010 or other kind of Delrin?
On Dupont web site there aren't these information

Here a link to an excellent design guide for Delrin

No mention of fatigue though. You'll have to ask an actual person at DuPont. They probably do have the data.

DuPont will certainly have the data. As Demon3 says, you will need to contact a real person there, preferably a technical support person.

You get more data if you can find an old technician as often data at that level is no longer in print as the marketing guru's tend to think it looks complicated and scares off prospective customers. They don't seem to consider the counterpoint that those scared of by real data are often headed for a disaster, and without the data to scare them off will charge on regardless. These disasters cost everyone involved.

This book should have it. I have the version for PP and it contains fatigue data.

Fatigue and Tribological Properties of Plastics and Elastomers (PDL Handbook Series) (Hardcover)

For all practical purposes, the useful life of a plastic component is equal to its fatigue life under conditions of cyclic loading such as those that occur in vibration. Equally important to materials engineers and designers are abrasion, friction and wear - tribological properties. Over 80 generic families are covered including thermoplastics, thermosets, thermoplastic elastomers and rubbers. Neat resins, blends and alloys, plastics with various combinations of fillers, additives and more are covered. Also covers plastics mated to plastics and metals.
