UltraTherm Magnesium Oxide Powder is essential for manufacturing high-performance electric heating elements that operate in extreme conditions. Its applications include:

•       Industrial Furnace Heaters: Ideal for heating elements in high-temperature furnaces, ceramic kilns, and heat treatment processes, where exceptional thermal conductivity in heating elements and superior MgO dielectric strength above 1000°C are required.

•       Industrial Process Air Heaters: Used in heating elements for high-power air heaters in industrial dryers, large-volume HVAC systems, and processes demanding elevated temperatures.

•       High-Power Immersion Heaters: Suitable for heating elements in immersion heaters for corrosive or high-viscosity liquids, where thermal stability and corrosion resistance are critical.

•       Cartridge Heaters: In compact heaters that generate significant heat in confined spaces, such as in the plastics industry, packaging, and molds, high-temperature MgO ensures effective insulation and a long service life.

•       Quartz and Ceramic Heaters: For heating elements requiring rapid thermal response and high resistance to thermal shock.

UltraTherm Magnesium Oxide Powder offers distinctive features and advantages:

•       High Purity: MgO content exceeding 97%, guaranteeing excellent MgO dielectric strength and high-temperature stability.

•       Superior Thermal Stability: Designed for continuous operation at temperatures up to 1200°C, making it an ideal high-temperature MgO powder for the most demanding applications.

•       Excellent Thermal Conductivity: Ensures efficient heat transfer from the resistance wire to the heater surface, improving energy efficiency and temperature uniformity.

•       High Dielectric Strength: Provides robust electrical insulation, preventing current leakage and ensuring the operational safety of electric heating elements.

•       Low Moisture Absorption: While not its primary characteristic, its composition minimizes moisture absorption under normal conditions, contributing to manufacturing process stability.

•       Optimal Flow: Controlled flow properties facilitate uniform filling in automatic machines, reducing production time and improving the quality of the final product.

UltraTherm Magnesium Oxide Powder, as a high-temperature MgO, requires careful handling to preserve its optimal properties.

•       Storage: Must be stored in a dry, cool environment, preferably in its original sealed packaging, to prevent moisture absorption. Exposure to moisture can compromise MgO dielectric strength and performance. Environmental humidity control below 60% and temperatures between 15-25°C are recommended.

•       Transportation: Transport in airtight containers to protect from moisture and contamination. Avoid excessive impacts or vibrations that could alter the powder's bulk density.

•       Usage: Before use, it is crucial to ensure that the high-temperature MgO powder is completely dry. If there has been moisture exposure, an annealing process (baking at elevated temperatures) is indispensable to restore its insulating properties. This step is vital to guarantee electrical safety in heaters and the efficiency of thermal conductivity in heating elements. Use personal protective equipment (gloves, mask) to avoid dust inhalation.

•       Annealing: For heating elements operating at very high temperatures, annealing the Magnesium Oxide powder before final sealing is a recommended practice to eliminate any trace of moisture and optimize MgO dielectric strength.

•       Automatic Filling Machines: The flow properties of MgO-UltraTherm are optimized for automatic filling machines, but it is important to calibrate the equipment to ensure uniform filling and adequate compaction density, which directly impacts thermal conductivity in heating elements and the lifespan of the heating element.

•       Specific Considerations: For applications requiring maximum working temperature (up to 1200°C), the HX-T9 grade is recommended due to its higher purity and lower impurity content, which translates to better MgO dielectric strength and stability at extreme temperatures. Monitoring MgO dielectric strength during the manufacturing process is crucial to ensure the final product's quality.

By following these recommendations, Magnesium Oxide for Electric Heating Elements ensures MgO-UltraTherm performs at its maximum potential, providing safe insulation and efficient heat transfer.
