It is indeed polystyrene by both B&W and Airdux. Back back in the
days when electronic distributors had outside salesman, I worked for
Hughes-Peters in Cincinnati. We sold both lines.

I don't recall significant differences between Airdux and B&W other
than
the color of the box. I still have some of both. And they were made
by
melting a hot wire into the plastic, most likely NOT nylon, delrin,
or
polycarbonate (Lexan) more likely polystyrene because of its better
RF
characteristics at the cost of temperature sensitivity. I'm sure I
have
catalogs for each.

Airdux is the stouter of the two - but still plastic - maybe a nylon

delrin, but not polycarbonate like miniductor.
