Medium Temp. MgO ZSM1B-1
● Features
ZSM1B-1 is medium temperature MgO powder, with good flow property and moisture resistance. It is mainly used in liquid and air flow heating elements with wattage loading less than 7W/cm2, such as fryer heater with the tube length of more than one meter, aluminum heaters (1500w-2000w), and air conditioner heating elements.
