Raw Materials

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Fabricating and Machining

Firebrick Repair Coatings

Firebrick Repair Coatings

Renew heat resistance and performance of worn firebrick

Firebricks

Insulate furnaces to minimize heat loss while adding flame resistance
