Recently, at the Port of Yingkou, Liaoning, containers fully loaded with 45 tons of CHIMAG electrical grade magnesium oxide (MgO) powder successfully completed loading and customs clearance, officially setting sail for South Korea.
The core product of this delivery is our highly favored CMM series, marking a further expansion of CHIMAG’s high-quality heating materials footprint in the Northeast Asian market.
Widely Used in Heating Elements & Industrial Applications
The CMM series electrical grade MgO powder is specially engineered for high-performance insulation and heat conduction in tubular heating elements. It is widely applied in:
- Industrial flange immersion heaters
- Water heater elements
- Electric oven and air heater tubes
- Cartridge heaters
- Appliance heating components (washing machines, HVAC systems)
With its excellent balance of electrical insulation and thermal conductivity, CMM series MgO powder ensures long service life and stable performance even under high temperature and high load conditions.
Proven Performance: Free Samples Pass Rigorous Testing
The successful delivery of this bulk order is built on a strong foundation of mutual trust.
Before establishing a formal partnership, to allow the customer to directly evaluate the product’s performance, CHIMAG provided free trial samples of our CMM series in advance.
After multiple rounds of simulation and prototype testing on the customer’s actual heating element production lines, the CMM series MgO powder demonstrated outstanding stability in:
- Dielectric strength
- Thermal conductivity
- Filling density and flowability
It perfectly matched their high-end manufacturing standards, ultimately leading to this 45-ton bulk purchase.
Key Technical Advantages of CMM Series MgO Powder
To meet the increasingly demanding requirements of modern heating element manufacturers, CHIMAG continuously optimizes its MgO formulation. The CMM series stands out with:
- High Purity MgO Content – Minimizes impurities that affect insulation performance
- Excellent Electrical Resistance – Ensures safety in high-voltage applications
- Stable Particle Size Distribution – Improves filling efficiency and consistency
- Low Moisture Absorption Rate – Reduces storage and transportation risks
- High Thermal Conductivity – Enhances heating efficiency and energy saving
These advantages make it an ideal choice for both standard and high-end heating element production lines.
Strict Attention to Shipping Details: Multi-Layer Moisture-Proof Packaging & COA
As an experienced industrial material manufacturer, CHIMAG deeply understands that shipping details determine the ultimate delivery experience.
Professional Sea Freight Packaging
Given the hygroscopic (moisture-absorbing) nature of magnesium oxide powder, all 45 tons of cargo in this shipment utilized:
- High-strength woven bags
