Dupré Vermiculite spread on molten metal acts as a dramatically effective
insulator. As the
photograph demonstrates, heat loss is minimal.
Dupré Vermiculite's dramatic insulation properties give you:-
Increased yields;
Substantially reduced oxidation;
Controlled directional solidification;
Retention of exothermic reaction;
Conservation of high temperatures when holding molten metal and
transporting ingots;
Improved working conditions;
and it's clean and pleasant to handle, inexpensive and readily available.
