How do Flexible and Elastic age in heat?


#1

I want to print some hard disk vibration dampening washers out of a soft material. I’m considering Flexible v2, Flexible 80A or Elastic 50A. Does anyone have any insight on how these materials hold up with age in an environment warmer than room temperature?

I’ve had cheap grommets made of rubber harden and crumble after 5-10 years of use.

Don’t have any info under prolonged heat, but parts will definitely degrade and tear more easily as they age - similar to rubber grommets.

We’ve heated the material up to 120C and ran force vs. deflection and saw only minor hardening with no cracking on a seal profile - rubber probably deteriorated due to sunlight or ozone - not temperature. I don’t have data on long-term effects at this time.
