Magnetic sheet (the main kind of flexible magnets) is made of strontium ferrite powder compounded with plastics or rubbers (NBB or CPE) by calendering process. There are 3 grades of magnetic sheet: Isotropic, Semi-anisotropic, Anisotropic, although the magnetic properties with (BH)max from 0.6 MGOe to 1.6 MGOe, special magnetic properties can be produced once the MOQ is met.
The main characteristics of a magnetic sheet are soft and flexible, it can be easily cut to any shape, bent, twisted, coiled, no loss of magnetic properties will happen during this.
Types of Magnetic Sheet
Pvc Laminated Rolls
Self-Adhesive Laminated Rolls
Dry Erase Finish Laminated Rolls
Colorful PVC Laminated Pieces
Manufacturing method of Magnetic Sheet
The production ways of the magnetic sheet are that firstly the materials are calendered in wide format rolls, the standard sizes are thickness(0.4mm, 0.5mm, 0.75mm, 1mm, 1.5mm), width(620mm, 1000mm, 1200mm, 1370mm) and length(10m, 15m, 20m, 30m). Special roll sizes can be custom made, also can be cut into small sheet-like A3 and A4 sizes.
The magnetic sheet is always multiple poles magnetized on a single face with magnetic pitch 1.5mm, 2mm, 2.5mm, 3.0mm, or 5.0mm. Though magnetized thru thickness is also possible for a magnetic sheet if it is required for special applications, a single pole will be on each face at this condition.
The non-magnetic face of the magnetic sheet can be plain or laminated with PVC, self-adhesive, dry-wipe PET, PP upon request, while the magnetic face is generally with UV coating.
Applications of Magnetic Sheet
The magnetic sheet is widely used in various commercial and industrial applications, mainly for Automotive Signs, Business Cards, Commercial Signage, Crafting Projects, DIY Home Improvement, Fridge Magnets, Large Format Graphics, Name Badge Holders, Office Presentations, Packaging Closures, Paint Masking Applications, POP & Tradeshow Displays, Promotional Giveaways, Warehouse Labeling, Windows & Door Seals.
