PVC? ABS? I'm just curious.
Looks like polystyrene to me.
Some of mine are some sort of hardwood .
One type I have seems to be mostly metal .
Other's , some sort of plastic .
So I guess it varies .
That would be my guess, too.
Depends. Even darkslides have changed plastics over the years. ABS and styrene are common but not universal.
I would say glass filled ABS.
I heard from someone who worked at holder facility in Burbank CA, ABS and Cycolac.
Hope this helps you....
This is a really good question. It is definitely a high impact material. It's very stable doesn't warp or bow when warm. The holders have a smooth surface, My guess would be a blend of some sort of styrenic and possible polycarbonate. High Impact polystrene, ABS. Doesn't look like it has a significant amount of glass fiber or you would be able to see it. Doesn't mean it's not filled with glass or mineral. This is a link to one Covestro's (formerly Bayer) PC/ABS blends there's thousands of different concoctions out there.
The darkslides almost look like a old thermoset like Bakelite or melamine filled with some sort of mineral or fiber. It's not an ordinary plastic.
Is there still NEW Fidelity and Lisco film holder being manufactured?
