I've had similar problems with pads separating and melting onto backing plates. This was with Meguiar's pad & plates. Then I tried using PC plates with Meguiar pads and still had meltdowns. Next I tried SM Arnold pads and haven't had a problem since.
When compounding isn't necessary but to remove minor to slightly moderate scratching/swirling I'll use it at speed 6 with a good amount of pressure. I can be abusive on pads because I'm trying to generate some heat like in the above circumstance. SM Arnold pads look & feel inferior to Meguiar's pads but I can't afford paying for new plates and pads every other detail and the difference is negligible.
Another problem I encountered was the loops on Meguiar's plates are very short resulting in a short lifespan. I'm guessing this is a profit thing.
I have asked Meguiars personnel about this but none of their suggestions worked hence the move to SM Arnold.
