When manufacturing magnetic elements for technical applications, GraviFlex® magnetic foils score points above all due to their temperature resistance, which - depending on the foil variant - covers a total range of -20° C to +200° C. This large "temperature window" opens up plenty of scope for using the magnetic sheet in both cold and hot environments. In practical terms, this means that magnetic elements made of GraviFlex® film from Schallenkammer adhere to icy-frosty surfaces as well as hot pipes, containers or machine housings. Product developers, designers and engineers can therefore use the magnetic foil for technically demanding tasks. It can also be used for the cost-effective realization of small batch sizes of moulded parts, machine elements or vendor parts for use in production, storage and assembly.
For lightweight magnetic products with or without a coating. Magnetic sheets 0.4–2.0 mm thick, uncoated, with PVC color film, or self-adhesive. Remanence 205 mT, HcB 119 kA/m, energy product 7.31 kJ/m³. For magnetic signs, magnetic pockets, die-cut parts, as well as advertising, planning, and organizational symbols.
Magnetic Sheets 170
For dimensionally stable magnetic products with higher holding force. Magnetic sheets 0.5–3.0 mm thick, uncoated, with PVC color film, or self-adhesive. Remanence 260 mT, HcB 183 kA/m, energy product 13.29 kJ/m³. For automotive magnetic signs, magnetic pouches, die-cut parts, and advertising, planning, and organizational symbols.
For technical film products with extremely strong adhesion
Single-sided magnetic foils with very high adhesive force made from an innovative neodymium-iron-boron alloy. Processing-friendly alternative to ceramic permanent magnets. Available in thicknesses from 0.8 to 6.0 mm and dimensions of 300 x 1,000 mm (W x L) as well as uncoated, coated with colored foil or with a self-adhesive layer on the back. With remanences of up to 650 mT, coercive field strengths (HcB) of up to 280 kA/m and energy products of up to 44 kJ/m3, it is an ideal semi-finished product for manufacturing highly magnetic stamped parts, strips and sheets for mechatronic assemblies. Temperature stable from -40° C to +100° C.
For flat components with front and rear magnetic adhesion
Double-sided magnetic, easy-to-process film with a standard thickness of 1.0 mm and a width of 610 mm. Available on 15-meter rolls uncoated, coated with coloured film, printed or with a self-adhesive backing. With remanences up to 263 mT, coercive field strengths (HcB) up to 203 kA/m and energy products up to 13.5 kJ/m3, a universal solution for product development, construction, production, office, laboratory and logistics. Well suited for the production of sensors, micromotor parts, packaging, heat-resistant paint covers, connecting elements and - with double-sided coating - colored reversible symbols.
For technical applications requiring exceptionally high holding force
Single-sided, multi-pole magnetized, anisotropic magnetic sheet with exceptionally high holding force despite its thin profile. Available in 0.5 mm, 1.0 mm, and 1.5 mm thicknesses with holding forces of up to 160 g/cm², 420 g/cm², and 600 g/cm², respectively. Ideal for reliable holding, securing, and positioning in confined spaces, as well as for demanding technical and industrial applications. The flexible magnetic foil can be custom-cut and further processed into stamped parts, strips, and customer-specific formats. Available in sheet sizes of 1,000 × 300 mm and temperature-resistant up to +70 °C.
