Russ, I have to thank you for introducing me to these PP filter caps. I learned about them in one of your postings a few years ago and have been using them ever since.
They are especially useful when restuffing an electrolytic can, where you never really want to open it up to replace the cap again. Ripple current and ESR are no longer a problem.
I measured less than 0.1 ohms ESR with a 10 uF polypropylene, compared to 4 to 6 ohms with a 10 uF 500V electrolytic. Big difference
