Could be mylar or polypropylene; I'm guessing mylar. Good for speaker crossovers and high voltage (tube) power supplies. If you've got a voltmeter and even just a nine volt battery, charge up one and then short the leads, let it sit for a minute and then measure the residual voltage. If it's a tenth of a volt, its polypropylene; if it's closer to a volt or more, it's mylar.

I suspect the manufacturer makes 'boutique' caps for various brands. Should be very good quality whatever type of dielectric.

Searched for more info but they could be some older type. I'm pretty sure the are polypropylene and heavy duty.
