APC Powder is an exothermic cum insulating powdered material commonly used for the casting of molten metal. This industrial-grade substance prevents the formation of the undesirable pipe over the top layers of the metallic melts by maintaining its molten state. It is flammable and ignites at the temperature of molten metal to compensate for heat loss. The expansion properties of the offered APC Powder ensures better covering to avoid contact with the riser.
