Characteristic

MTM is a medium temperature Electrofused Magnesium oxide powder. Mainly used in liquid heating elements with wattage loading at 8w/cm2  and air heating elements like Electric Oven Tube with wattage loading less than 7w/cm2. Elements stuffed with this material are proposed to be annealed at 200°C to 400°C for 2 to 4 hours.

Usage: Mainly used in Soybean Milk Machine Tube; Electric Oven Tube and Air Conditioner Tube of medium wattage loading.
