Can packers expire? I hear some silicone expires so I’m curious.
autumn says:
takes off trans hat and puts on polymer scientist hat
after the silicone has polymerized, its not gonna expire. You can absolutely degrade it, but you're not gonna degrade it by general use/wear. Silicone polymers are extremely resistant against heat, and a lot of chemicals. Yeah they will probably degrade, but this is over the span of years of heavy use (I don't think just wearing a packer would constitute heavy use). The expiry that I think you might be thinking of is uncured silicone, which can "expire."
hope this helps. maybe other people who follow the account will have other experiences with them though.
edit: i really hope you aren't exposing (by exposing I mean like, dipping it in beakers of these solvents) your packers to the chemicals that I'm thinking of, that would be very weird, don't wear your packer after you submerge it in DCM or chloroform or like hot acid, that's not good for your skin.
The survival strategies employed by one of the most aggressive, territorial and venomous ant species may pave the way to revolutionize robotics, medicine and engineering.
Fire ants survive floods by temporarily interlinking their legs to create a raft-like structure, allowing them to float collectively to safety as a unified colony and then releasing to resume their individual forms.

I hate that my phone cam didn't capture the details on these. Even the colors were a bit off - it's supposed to be granite gray but the lightings are turning them into blue
god sometimes i wish i was a polymer, life would be so much easier if i was a polymer.
i would just have to carry your groceries and be so helpful to you, or i could play music for you on a second-hand record player, i could brush your teeth for you, i could be so useful as a polymer.
trust me i wouldn’t be like one of those nasty polymers. i wouldn’t be part of the great pacific garbage patch or disintegrate into microplastics in your oceans and in your food. not me sir no i’m not like the other polymers
