Flexible Ferrite Magnetic Sheet

Magnetic Sheet

Flexible magnetic sheet is made from strontium ferrite particles dispersed in a flexible polymer binder, calendered into thin sheet form. It is easily cut with scissors or a knife and can be printed, laminated, or adhesive-backed. We supply uncoated, adhesive-backed, and PVC-laminated grades in standard roll widths.

Technical Properties

Typical values across stocked grades. Specific grade data sheets available on request.

Magnet TypeHard ferrite (strontium ferrite SrFe₁₂O₁₉) in vinyl or NBR polymer binder — generates a static field. NOT a soft-ferrite EMI absorber
Magnetic Energy Product0.6–1.1 MGOe (isotropic) / 1.2–1.6 MGOe (anisotropic)
Coercive Force (Hc)1400–2000 Oe (flexible anisotropic)
Curie Temperature (intrinsic)~450 °C (strontium ferrite); however, polymer binder limits service ceiling far below this — see Temperature Range
Temperature Range-20 °C to +80 °C continuous (vinyl/NBR binder limit; polymer binder decomposes above ~150 °C — the magnet powder itself remains magnetic)
Thickness Range0.4 mm to 3 mm
Standard Roll Widths300 mm, 600 mm, 620 mm
Density3.2–3.8 g/cm³ (commodity isotropic toward lower end; high-loading anisotropic toward upper)

Common Applications

  • Point-of-sale signage and displays
  • Warehouse and workshop labelling systems
  • Tool organisation and shadow boards
  • Door and panel closures (light duty)
  • Craft and educational use
  • Light-duty mounting and fixturing on non-ferrous panels (note: this is hard-ferrite static magnet sheet, not a soft-ferrite EMI absorber — for AC magnetic flux suppression specify soft-ferrite NiZn or MnZn sheet from Laird, Würth, or KGS)

Not Recommended For

  • Polymer binder decomposes above ~150 °C — the sheet loses structural integrity; intrinsic strontium ferrite Curie point is ~450 °C, so the magnet powder itself remains magnetic. Service is limited to 80 °C continuous by the binder
  • Not a structural magnet. Pull force is modest compared to sintered NdFeB or ceramic magnets
  • Adhesive-backed grades have limited repositionability, since the adhesive is permanent once applied to smooth surfaces
  • Not suited to outdoor use without UV-resistant laminate; bare ferrite/polymer compound degrades in direct sunlight

Available Grades

Flexible Magnetic Sheet (Uncoated)

Plain ferrite/polymer sheet with smooth dark brown surface. Accepts direct printing (screen, digital, UV) or can be used as a magnetic substrate for attaching to steel surfaces.

Flexible Magnetic Sheet (Adhesive-Backed)

Magnetic sheet with pressure-sensitive adhesive on the non-magnetic face. Peel-and-stick application to non-ferrous surfaces — turns any flat panel into a magnetic mounting surface.

Flexible Magnetic Sheet (PVC Laminated)

White PVC film laminated to the display face for a clean printable surface with improved UV and moisture resistance. Preferred for signage and display applications.
