[Hammarlund] [Fwd: Polyester or polypropylene?]

[Craig Roberts]

Okay gurus -- here's one for the hardcore restoration mavens:

Which is preferable for general paper cap replacement in HF circuits, 
metallized polyester film or metallized polypropylene film?

I tend to use them interchangeably, depending upon what's at hand.  I 
prefer the tubular film caps to Orange Drops (or clones) simply because 
they're not as awkward to install in tight spaces and the leads are 
easier to dress and insulate from nearby objects..  Is there any 
operational difference in these film types?  Polypropylene sounds cooler 
and more "techie".  I mean, polyester is what leisure suits were made 
from.  Ughh.  I don't suppose that would be considered an engineering 
criterion, though :-) .

Thanks and 73,

Craig
