Type: heavy silicon modified moisture resistant electrical grade Magnesium Oxide L series

Characteristics and uses:

L series is a heavy silicon modified damp-proof Electrical Grade Magnesium oxide, divided into A B C D four grade specifications, electrical grade magnesium oxide is suitable for non-air-fired electrical heating components (such as copper, aluminum, Bundy or stainless steel pipe, such as strong convection, contact heat conduction), not suitable for high temperature heat treatment (such as annealing at 1050 C), with strong moisture resistance, can be. Simple sealing. Before sealing, it is recommended that the components should be dried at 200 c -350 C for /2-4 hours.

Suitable for: all kinds of low load heating pipe, such as: drinking machine pipe, soybean milk machine pipe, bread machine pipe, electric iron pipe, coffee pot pipe, etc.

Main chemical components


Mesh size distribution:


Note: + 425 m and - 45 m contents will be strictly controlled within the prescribed range, in order to obtain the required compaction and flow rate, the content of other items may exceed the above range. (special requirements can be produced according to customer needs)

Flow density and density:

The density of compaction is T.D. (g/cm3): 2.30-2.45 g/cm3.

Flow velocity (F.T. s/100g): 35 + 4

Flow rate (F.R. s/100g): 175 + 20


25KG cartons, woven bags, 1 tons of pallets or packaging according to customer requirements.

Safety and storage:

Electrotechnical grade magnesia powder is non-toxic and has trace dust. It is recommended to wear masks and gloves during use. The product should be stored in dry place, and it is recommended to be used within 12 months after the factory is released.

Leakage current VS pipe surface load


Power load (W/cm2)

Test conditions:

Tube: SUS304, Phi 8 x 0.5, L500 wire: 0Cr25AL15, 0.35mm, wire coil 2.3mm

Shrinkage: 8.0 6.6 mm heating length: 450 + 10 mm drying treatment: 250 / 1 Hr, power on time: 30 min

Note: the chart shows that the typical value of the product under the specified test conditions is L/C for reference only.


Heavy silicon modified moisture resistant and electrical resistant Magnesium Oxide L series products:

1) strong moisture resistance:

Most manufacturers at home and abroad produce moistureproof electrical grade magnesia powder mostly moistureproof ability can only reach below 2000M_, and the company's moistureproof high-temperature electrical grade magnesia L series products are more than 1x106M_moistureproof ability, not sealed by wet test (humidity 92% temperature 50) 72 hours above the long time storage, insulation capacity is also not available. Decrease; strong moistureproof capability can greatly improve the production cycle. To reduce sealing material requirements, ordinary silica gel can be used for sealing.

2) strong insulation capacity:

Even if it is used in the electrothermal components with low working temperature and high insulation performance requirements, different specifications and grades of products can be selected according to the technical specifications of the electrothermal components.

3) the product is uniform in color, beautiful in appearance and small in dust, which is beneficial to improving the environment of adding powder.
