A/B Cold foam


Has anyone used A/B cold foam to make armor?
I was wondering if this would work.

Re: A/B Cold foam


I have some cold foam foot armor for my 89 boots that David made several years back. It's good for this,but I don't know about full armor.
It's soft and flexible,but I don't know if it would be strong enough.
I have velcro on the inside--the 'foam' side--and I have to be very careful taking them off by getting my fingers in between the velcro,then peeling it off,or it could rip.

I assume what I have is the same or similar stuff to what you're referring to.

I was thinking maybe useing cold foam with a latex skin to help make it a little stronger.
I figure it would be lightweight as opposed to latex or urethane.

DavidYR1 did that back in 2002/2003 and though he'll say it was successful I would have to disagree (and enough other guys that were around at the time will agree with me, Sorry Dave). The latex and the cold foam have different stretch vs return to original properties and what usually happens is the latex winds up peeling away from the foam and the foam tears. Then again the latex "skin" he (David) was doing was quite thin. I made a suit the same way back around the same time but made my latex quite a bit thicker. In the end it was much more durable but the separation issue was/is still somewhat evident. I still have the suit I made (it was used recently as a Robin suit on Halloween and held up well) and have a Panther suit that I got from Dave that he made that I wouldn't even think of trying to wear because it would come completely apart by the end of the evening. It's even got buckling just from being on display in my basement, (NEVER WORN). Bottom line, it "can" be done but it's hardly worth the extra effort adding the foam. BTW, the foam HAS to be added before the latex is demolded or it will shrink funny and take the latex with it.

Re: A/B Cold foam


I've been wondering if this would work too. I've used Flex Foam-IT to fill my latex master cowl and afterwards I was able to peel the latex away from the foam even though I added the foam before the latex skinned over.

I've seen pictures on the Smooth-On site that are masks make from Flex Foam so I'm wondering if you got a really dense version of the foam, sculpt the cowl or armor thin and cored it, it may work. It's something I'd love to try once I've figured out cored molding. Just to see how well it works, if at all. Would be a cheaper alternative to foam latex. Well maybe not cheaper but you wouldn't need the oven and experience in mixing the foam.

Re: A/B Cold foam


I found a good tutorial HERE which gave me the idea of cold foam and how it may work for armor. But if what Ed say's is true it would just be a waste of time.

I would never say it's a "waste of time", depending on what you want to accomplish. What I would say is that the basic latex piece needs to be thick enough that when the cold foam pulls away it won't deform the external surface of the piece. Also cold foam, being urethane can only be glued with cyanoacrylate (not sure if that's spelled correctly) type glues (like super glue) which "usually" are quite rigid so I suggest using the foam as just a backing/support under certain areas, like chest muscles and leg muscles but keeping it only latex at the edges to facilitate glueing. :wink

You could always make foam backed urethane armor . Would be more work but would also stand up better.
