I wonder if they'll switch to polyacrylamide (kapton) tape. It's already used on packs pretty frequently just not on the tabs. Heat shouldn't damage this material.
- andrewxdiamond 4y agoKapton tape is also quite expensive and overqualified for this task. I think the engineers will be able to squeeze out a lot cost by using something more “barely-capable”
- tuatoru 4y agoCellulose tape?
- joecool1029 4y agoThat would be among the worst choices for tape. Gets damaged above 50C, decomposes above 100C, biodegradable and flammable: https://s3-ap-southeast-2.amazonaws.com/wc-prod-pim/Asset_Documents/Sellotape%20Label%20Tape%20SDS.pdf https://s3-ap-southeast-2.amazonaws.com/wc-prod-pim/Asset_Do... Might as well seal it with the yellow adhesive Cyberpower uses on their UPS's which decomposes into flammable and conductive substances.
- astangl 4y agoI was actually just reading about Kapton yesterday, and stumbled upon some info about its deterioration being hastened by heat. See https://en.m.wikipedia.org/wiki/Kapton#Characteristics https://en.m.wikipedia.org/wiki/Kapton#Characteristics
- mitthrowaway2 4y agoKapton tape is polyimide, not polyacrylamide, isn't it?
- joecool1029 4y agoThanks you're correct, polyacrylamide is a cool unrelated material.
