IG 70 High temperature strength board |
IG 70 is a revolutionary new development in high-temperature strength board. Operating in high temperature environment, IG 70 has a low thermal conductivity, high strength, and size stability all other materials of the current market can not match.
In many international steel plants, IG 70 has been recognized for being the material for ladle and tundish, because of it's strength and safety. |

The data above is measured by the British Ceramic Society (Ceramic Society) using the Calorimeter Panel Method method. It has a higher measurement then the data provided by manufacturers, but should still be more accurate. (Hot Wire Method should not be used to test material like IG 70 and other non-homogeneous materials,so there will be an error in the table above) |
