MgO powder suit to working condition: 5W/cm squ surface loading (400-500degree Centigrade)

GG-#6 is mainly used for stainless steel electric heating tubes with water or as the heat transfer medium. It need anneal to expel moisture at the temperature at 350oC for 5-6 hour

It is usually used for Soya-bean milk extractors and electric kettles.
