INSTILL(TM) open-cell polystyrene foam is for refrigerator and freezer, insulating shipping container, and cold storage-unit applications. The material is made from a non-hygroscopic material, making pre-conditioning INSTILL core prior to evacuation an optional step. Supplied as a lightweight board stock, it requires no special liner for use within the barrier pouch. INSTILL core also minimizes problematic dusting and fragmenting that can compromise seal integrity and vacuum pump reliability.
