MAGNETIC COMPOUNDS FOR EXTRUSION, INJECTION MOULDING AND CALENDERING


Magnetic compounds are made by embedding a Barium or Strontium ferrite reinforcement into a polymer-elastomer matrix using open or closed mixers. The quamtity of ferrite powder in the compound may be higher than 90% of total weight. Ilpea supplies both isotropic and anisotropic compounds, which can be extruded, calendered or injection moulded to make finished products, such as:

1) Flexiblle magnetic profiles for refrigerator door gaskets
