What is this?

[SignStudent]

Similar to ultraboard but has more dense foam and the faces are like a wood veneer. The stuff is very hard, almost like MDO and doesn't dent at all. The foam is black all the way through, not just painted black on the outside.

hmm kinda looks like sintra?

I agree, looks like black sintra to me also...

 

[SignStudent]

Hmm, I've never used a thick brand name sintra, only the thin economy pvc stuff. The economy pvc seems kinda soft but this stuff is much harder and totally rigid. Is actual sintra more rigid/hard, or maybe it's just because it's thicker?

 

[SignStudent]

I just checked and if I push my fingernail into the economy pvc it leaves a permanent indentation but there's no way I can push my nail into the stuff I'm looking for.

Durafoam?

Komatex?

 

[SignStudent]

From what I've found Komatex is pretty much the same as Sintra. Anyone know for sure if either of them are hard enough that you can't dent them with your fingernail?

Is durafoam a sign material? The only stuff I can find about it is for roofing or exercise mats.

HDPE High Density Polyethylene???

Sintra, Komatex, Celtex that's what it looks like to me also. I cut tons of that.

All those brands are PVC all the way thru....no foam that I remember. Years ago I used half inch foam board with a thin wood veneer front and back...loved it, then they stopped selling it
