**Casting with flexible foams** Posted: 5/7/2011 11:37:14 AM

Sometimes, very soft polyurethane foams can have a tendency to collapse. If this happens then this could be due to some of the common reasons. Using a tin based condensation silicone rather than a platinum silicone. Using the wrong release agent or not allowing the fumes that is generated during curing to escape sufficiently. a simple cure to a cast that has collapsed is to squeeze the foam cast ASAP and expel the gases from the foam replace the cells in the foam with fresh air.
