Material information

Useful information

Rubber Ferrite (magnetic sheets) are made of hard ferrite powder and an elastic, thermoplastic binder and can be produced in the form of sheets and strips and as extruded profiles. As a binder, EPDM is generally used for thicknesses of 0.5 mm to 2 mm, and for thicknesses of 1 mm to 15 mm nitrile.

There are isotropic to anisotropic qualities, with anisotropic qualities having higher magnetic values. They can be magnetized on one or both sides multipolar or over the height. Through an iron backing plate (thickness at least 0.3 mm), the adhesive force can be significantly increased.

Rubber Ferrite is resistant to air, ozone, water vapor and weak acids / alkalis. The swelling or even the dissolution of the material may trigger by gasoline, mineral oil, acetone, benzene and chlorinated solvents. Rubber Ferrite bound with EPDM has a max. Operating temp. of 80°C, those with nitrile binder 100°C, in short term even 150°C.

There are different versions available:

The advantage of this material is the high flexibility, the rational production for large quantities and the ease of machining by punching, cutting with scissors, drilling, etc.
