Good Morning! My company recently purchased a drum of Epsilyte T175A expandable polystyrene beads to run process testing. These beads are designed for lost foam casting and include additives to improve metal flow. We have more beads than we need internally for testing, so we figured we would make them available to others who wanted to try out the "real deal", but didn't want to buy a whole drum. You can find them here: https://www.ebay.com/itm/177460679910 Also, a low-tech primer on how to expand beads in a mold is here:
We mainly do investment casting. Our interest in lost foam stems from our desire to replace some wax and resin components with less expensive EPS components.
