Details:

With the magnetic rubber 150/180, Schallenkammer Magnetsysteme offers an extremely flexible material solution for the production of magnetic moulded parts and components. The anisotropic material made of a rubber-like polymer with embedded strontium ferrite powder can be easily machined and is an inexpensive alternative to ceramic magnets. It has high holding power, achieves long service lives and is resistant to ozone, water vapour and diluted chemicals.

Contactless contactors, covers for painting work, catching systems above conveyor belts and fastening elements are among the typical products made from Schallenkammer's magnetic rubber 150/180. Wherever rings, strips or surfaces with a high magnetic holding force are required, the material, which is available in sheet and tape form, is a highly interesting solution. It can be punched, drilled, sawn and cut (also by water jet) without splintering (!), proves to be highly resistant to weathering and ageing and is insensitive to ozone, water vapour and diluted acids and alkalis. In many cases, the flexible material is an inexpensive alternative to ceramic magnetic materials.

Schallenkammer offers its magnetic rubber 150/180 in two variants: Type A has magnetisation axially aligned across the height (thickness) and is supplied in blanks with widths of 140 mm; Type C, on the other hand, has a single-sided multipole surface magnetisation and is available in blanks with widths of 440 mm. The length of the sheets or strips can reach up to 2500 mm; the standard stock length is 1040 mm. The thicknesses range from 1.5, 2.5, 3.0 to 8.0 mm in eight gradations.

Semi-finished or finished part

Schallenkammer supplies the magnetic rubber 150/180 as a prefabricated semi-finished product or manufactures 2D moulded parts from it according to customer requirements - also with coloured film coatings and adhesive film. Even individual geometries can be realised very economically in small quantities. And for those who require particularly high adhesive forces for their application, the moulded parts made of magnetic rubber 150/180 type C can also be provided with an iron backing made of sheet steel. With a material thickness of 2.0 mm, this doubles the holding force of the material from 75 g/m2 to 155 g/m2 !

Schallenkammer's magnetic rubber 150/180 is suitable for applications with continuous temperatures of up to 100° C and can also withstand short peak temperatures of up to 150° C. If this value is exceeded for a longer period of time, the magnetic rubber can be used as a magnet. If this value is exceeded for a longer period of time, the material loses its flexibility and begins to solidify (bakelisation). The material is non-toxic and complies with the European standard EN71/3.
