Product Description
Specifications
1.Used for semi-anisotopic bonded magnetSound dampening of automotive, fridge magnets,visual aids and
Sealing strip
1. Introduction of Product
BMXF-2H is a barium ferrite powder for the preparation of semi-anisotopic bonded magnets. It is compatible with the matrix material, such as CPE, NBR. Permanent magnets are formed by extrudering technique.
2. Typical Powder Properties
Chemical Composition BaFe12O19
Average Partical Size 1.4-2.0 µm
Moisture <0.5 %

4. Test condition
Test condition A:
40 grams of powder mixed with 4 grams of wax heated at 110°C for 15 minutes to make the wax melt. Then make the mixed powder pass through a 40-mesh sifter. 18 grams of the - 40-mesh powder is compressed at a 1.6´104 N/cm2 pressure to get a green sample for magnetic properties measuring.
Test condition B:
Compounding Equipment: Two roll rubber mill.
The two rollmill is heated to 80 °C . 32 grams of binder is sheeted onto the mill and 460 grams of BMXF-2H powder is added and mixed with the binder. This mill sheet is calendered onto another which roll gap is adjusted to produce a 2.7mm sheet. A portion of this mill sheet is evaluated to determine magnetic properties.
