i was told by a animation major in colledge that there was this foam stuff that goes on armatures for claymation instead of the clay, so its more durable and easy to work w/. so if anyone has heard of this or knows where to find it or how to use it or make it or anyhting please post.

my grammer is looking better ever day

he/she was probably talking about a foam latex. if you take a look at my link page and check out the (easy) stop motion armature page you'll see an armature at the bottom, i was going to sculpt over that, mold it, and foam latex to make a completed puppet out of that, but decided i like the armature as is right now. a soft polyfoam like polysoft can be used, i've seen it done, although you'd probably need to brush in a latex skin first.

the other pictures and random babbleing give an idea how to use hte same foam you might find in a couch/sofa to fill out the puppet. that foam would need a "skin" put over it.

It might be called foam rubber too. But I'm not rellay sure. I think I'm incorrect, but look for it anyway, just to be sure.

Crazy Lou is right on the money, as usual.

Foam latex is widely used in make up for prosthetic appliances, but it is also used as a casting material for animation models with internal armatures.

Rubber is a category of material, not a product. Rubbers can be latex (partially or wholly based on vulcanised rubber tree sap), or they can be synthetic (urethanes, silicones, vynil, etc.)

Foam rubbers are lighter, much softer, and inherently compressible, while solid rubbers are generally just elastic and have memory. Foam rubbers simply are a foamed solid - the rubber material is encapsulating air bubbles, much like a sponge does. Hot Foam is a name for foam latex, which ust be vulcanised with heat. Cold Foam refers to polyurethane foams, which require no heating.

P.S. While Cold Foam doesn't require vulcanisation, I have heated my molds when making prosthetics in the fall. With the lethal fumes given off by the chemical reaction involved, working outside is the only acceptable procedure without professional vapor management equipment. Sorry, even organic filters don't work on Isocyanate gas, so forget a respirator. Since the reaction should take place at 70 degrees F and the outdoor temperatures have been lower, I have had to compensate with a warm mold to keep the reaction from being inhibited.
