foam or rubber molding

[engineerjoe]

I am looking for some foam or rubber material that I can mold to a specific shape. The two main constraints I have for the material are as follows: it needs to work quickly (30 minutes or less) and form shape at room temperature. To be more specific I need to press a shape into the foam or rubber and have the material take the shape fast. The reaction can be exothermic but must not create so much heat it could cause a burn human skin. Does anyone know of a material like this? Does a product already exist that does this? Could I make it myself? Thank you

platinum-catalyzed silicone may be an option.
