> We have carried out ten [thermomechanical] recycling cycles, and the epoxy has not lost any significant mechanical strength in the process

Chemical dissolving is only needed for carbon fiber composite. 90% of the resin was cited to be recoverable in this process.

I saw that passage, which addresses that durability doesn't degrade through recycling cycles. But what I was curious about was whether this epoxy is more susceptible to weakening when exposed to heat in working environments, perhaps at lower threshold temperatures than common epoxy. Similarly, I wondered whether there were any chemicals which are commonly encountered in working environments which could serve as dissolving agents and damage this epoxy.
