Flexible rollable soft magnetic sheet, also known as flexible rubber magnet sheet, is a new type of composite magnetic material made of ferrite magnetic powder, rubber polymer and auxiliary additives through calendering, extrusion and vulcanization molding. Different from rigid hard magnets such as NdFeB and ferrite magnets, this soft magnetic sheet has excellent flexibility, bendability and rollability, can be freely curled, folded, cut and pasted without cracking or demagnetization, and has unique application advantages in flexible installation and special-shaped fitting scenarios. The overall structure of the flexible soft magnetic sheet is uniform and soft, with moderate toughness and tensile strength, and can adapt to curved surfaces, irregular surfaces and flexible base materials that rigid magnets cannot match, solving the installation limitations of traditional hard magnets in complex structural environments.

In terms of material performance and characteristics, flexible rollable soft magnetic sheets have stable magnetic properties, uniform surface magnetism and good magnetic permeability. Although their magnetic strength is lower than that of NdFeB hard magnets, they have obvious advantages in flexibility, processability and cost performance. The product has excellent weather resistance, can work stably in the temperature range of -20℃ to 80℃, and is not easy to age, deform or demagnetize in conventional indoor and outdoor environments. It has good waterproof, moisture-proof and corrosion resistance, no need for complex surface anti-corrosion treatment, and long service life. In addition, the flexible magnetic sheet supports arbitrary cutting and shaping, and users can cut it into various sizes and shapes according to actual use needs without special professional equipment, which is extremely convenient for on-site construction and personalized customization. Most flexible soft magnetic sheets are equipped with self-adhesive backing on one side, which can be directly pasted on metal, plastic, wood, glass and other flat surfaces, with simple installation and firm bonding.

The application scenarios of flexible rollable soft magnetic sheets are extremely extensive, covering civil life, commercial advertising, industrial auxiliary fixed, intelligent equipment and many other fields. In the advertising and printing industry, it is widely used for magnetic advertising stickers, car body advertisements, display board backgrounds, promotional display cards, etc., which can be freely pasted and disassembled without damaging the pasted surface, and is reusable and environmentally friendly. In daily life and office scenarios, flexible magnetic sheets are used for refrigerator stickers, whiteboard magnetic stickers, file fixing, door and window sealing and fixing, which are convenient and practical. In the industrial field, they are used for auxiliary fixing of production line accessories, magnetic shielding of electronic equipment, flexible magnetic induction components of small intelligent sensors, and fixing of mechanical auxiliary parts. In addition, flexible soft magnetic sheets are also applied in the fields of toy manufacturing, handicraft production, medical auxiliary equipment and automotive interior accessories. With the continuous upgrading of flexible functional materials, the optimized flexible magnetic sheets with enhanced magnetic force and high temperature resistance are gradually applied to emerging fields such as flexible wearable devices and soft robot accessories, showing broad market development prospects.
