Every magnet in our catalog up to this point has been a fixed, molded shape - discs, rings, arcs, cylinders. This A4 sheet is different: a flexible rubber magnet you can cut, bend, roll, or print on, sized to a standard A4 sheet (297x210mm) so it drops straight into signage layouts, whiteboard fabrication, or any application built around a printable magnetic surface.
Material And Construction
The sheet is made from strontium ferrite powder bound into a flexible vinyl matrix - the same composite family used across the flexible magnet industry, available in isotropic or anisotropic grades depending on the pull-force profile you need. Standard thickness runs from 0.3mm to 2mm, with a flux index around 50kG²·mm² and dimensional tolerance held to ±1%. Because the material stays flexible after production, it can be cut, scored, rolled for shipping, and re-flattened without cracking - something none of our rigid NdFeB or ferrite products can do.
Surface Options And Applications
Three surface options cover most use cases: plain adhesive-backed sheet for mounting, printable glossy for high-contrast graphics, or printable matte for a low-glare finish that's easier to write on. That range makes this sheet useful well beyond typical fridge-magnet territory - signage fabricators cut it to shape for POP displays, office suppliers turn it into dry-erase boards, and print shops run custom logos directly onto the surface for promotional magnets and name badges.
Customization
Standard sheets ship at a 1,999-sheet minimum order, but custom logo printing, custom packaging, and custom graphic patterns are available starting at just 200 sheets - useful for testing a design before committing to a full production run. HIMAGNET supports minor customization, drawing-based customization, sample-based customization, and full customization depending on how developed your specification is. Delivery typically runs 22-30 days for standard orders.
Handling Notes
Flexible rubber magnets are far more tolerant of bending and impact than sintered NdFeB, but they should still be stored flat or loosely rolled rather than folded sharply, which can create a permanent crease and a local weak spot in the magnetic field. Keep sheets away from sharp edges during cutting to avoid tearing the vinyl matrix. Quality is backed by ISO9001:2000 certification, with CE and RoHS compliance for the finished product.
Common Questions
Can this be cut into custom shapes?
Yes - the sheet is designed to be cut with standard tools (craft knife, die-cutter, laser cutter). Send your shape requirement and we can also pre-cut to size in production.
What's the difference between isotropic and anisotropic grades?
Anisotropic sheets are magnetized in a single fixed direction for stronger pull force; isotropic sheets can be magnetized in any pattern, which is more common for printable and multi-pole applications. Let us know your use case and we'll recommend the right grade.
What's the minimum order for a custom logo?
200 sheets for custom logo, packaging, or pattern printing - well below the 1,999-sheet minimum for standard unprinted sheets.
