Suflex, styroflex, polystyrene, all the same thing?

syn · Jul 28, 2006

Are they the same thing? I was looking at BA284 which uses Suflex,
but on the schematic they appear to be non polarized. Then i found a photo on the net of Suflex caps but they look same to polystyrene (styroflex) which are polarized. I'm :roll: What could i use instead of Suflex caps no one seems to sell them?
thanks

EDIT
Suflex = is an actual company producing Capacitors
Mylar = brand name of a Polyester compound used in Capacitors
Styroflex = brand name for a Polystyrene compound used in Capacitors

I've never heard of Suflex?

Polystyrene (styroflex) is non-polarized, though often marked with a black ring for outer-most layer indication, which can be important in HF-circuits...

That "black ring for outer-most layer indication' led me into the belief that they are polarized...
