I´me searching PVC for covering EPS.
It´s a very strong material, 3mm, porous, and bend´s with a heat ventilator (the colour is yellow, a litlle darker).
It comes with about 30 cm x 1 m, and it´s for use between fiberglass cover, with epoxy resin vacuum bagged, for covering EPS.
As I don´t find in Portugal, can you tell me what´s the correct name to find it, or the stores/industry that sell´s it???
Does anyone uses this in surfboard construction (It´s not the same as Tuflite…)
Divinycell
Sounds likr Airex
The yellow/gold stuff is the 60 kg/m3 foam
Perfect for sandwich skins, although I can only get it in 5mm thickness
Really fine pores, so not really “porous”.
It means you don’t use much resin.
Completely thermoformable
What about Roahcell??
Is it good??
Rohacell has the best physicals of all the sheet foams, but it’s very expensive.

We use it all the time…as a space qualified antenna substrate. It handles high proton energy and atomic oxygen well. Surfboards? I’ve often fondled some pieces at work and thought about it, but I use balsa for mine.

These are important criteria for surfboards… if you’re in space. For all of you swaylockers that think I’M crazy, pompano is a good example of the kind of space satellite building engineers (and/or other aerospace parts and pieces) we’re surrounded with here in Brevard County. I went to college with a bunch of them and blame them for all my composite structure addiction ‘‘problems’’.
Yeah, well, you gotta do what you gotta do to afford surf trips these days. 
I can say we’re trying to move to aerogel in some applications now. That is something you definitely don’t want as a surfboard material. At least not yet. It crumbles in your hands.
I actually looked into procuring some Aerogel, but found that all the surfboard -sized pieces were reserved for NASA and
the Jet Propulsion Laboratory. And you don’t even want to know what those pieces would cost. A fascinating material that
was the result of a bar-bet back in 1936 or something ridiculous like that…
And although it’s stupid strong (in some measures) and by far the lightest ‘‘foam’’, it’s water absorbing qualities alone
preclude it’s use as a core material in surfboards. I am jealous that you get to handle the stuff though.
LOL, thanks Mike.
