KR> experimenter Polyisocyanurate Foam

2009-03-22 Thread mbz...@comcast.net


You might want to double check the Tuff-R 



I think it has an aluminum laminate on both sides 



I'm not sure, but if thats true, the laminate IMHO makes the foam useless 



for construction. Also I'm not sure if the properties of the foam are with or 
with out 



the aluminum laminate. So if you peel the laminate away, the properties 



might go down the hill.

Thanks Dave,

I compared properties of the two and found :

Both are made by "Dow" and are suppose to be unaffected by ethanol laden 
fuels.

"Tuff-R" has a much higher flexural strength & will absorb much less 
moisture.

There's a locale supplier that carries up to 2" thickness and the price is 
right!

The possible draw back for Tuff-R":  an operation temperature range of -50 
to +190 F. and having to remove facing materials from each sheet.

The plus for "Trymer 2000" is it's operation temperature range of -297 to 
+300 F, but I don't remember seeing that product name in my travels so far.

It seems Urethane Foam has an operation temperature range of 65 to +200 F.

I guess my next question is, "What do the high priced urethane foams have 
that 'Tuff-R' doesn't ? "

You should also look for Trymer 2000. I found a supplier nearby a
few years back, but they don't carry it anymore.

Is anyone using Polyisocyanurate Foam, (e.g. Tuff-R) in their construction?
