Can Hypalon be safely cut?
The material is a polyethylene (CSPE) synthetic rubber (CSM). Sometimes with a fiberglass mat layered in the middle for added strength.
I was thinking it would be really cool to use the Glowforge to repair or replace parts of my Klepper foldable kayaks. https://www.klepperamerica.com/
Hypalon is a popular material used in the hull of that style of Kayak.
