MagFlex® Ultra A4 Flexible 3M Self-Adhesive Magnetic Sheet

Our strongest self-adhesive flexible magnetic sheet has more than double the pull-strength of our standard sheet but is still easily cut to size which makes it ideal for creating magnetic pictures, artwork, signs or displays.

MagFlex® sheets are not suitable for sticking magnets to as the strong magnetic field will realign the magnetic particles in the sheet. View our FerroFlex® sheets if you need a surface to stick magnets to.

MagFlex®+ Ultra self-adhesive flexible magnetic sheets are easily cut to size with scissors, making their creative uses endless. Whether you are a craft enthusiast, want to create your own signs or make your artwork or photos magnetic you will find our magnetic sheets really useful. MagFlex®+ Ultra flexible magnetic sheets are double the strength of our standard version but are still much less powerful than 'hard' Neodymium magnets and are therefore much easier to handle and work with and of course, each sheet is made from non-toxic material. If you are looking for a flexible sheet to create a magnetic surface for 'hard' magnets, then you should use our ferrous sheet and tapes.

These magnetic sheets utilise a firm acrylic pressure-sensitive adhesive that substantially increases in bond strength with natural aging. While the initial touch bond strength is enough to keep the grip secure, to ensure the adhesive can withstand the pull strength we recommend allowing between 24 to 32 hours for the adhesive to fully cure.

This product is often utilised in applications where you require an instant fixing. It can be attached and removed without the need for additional equipment, greatly decreasing downtime and labour. One example where our flexible magnetic sheets are handy is in steel containers, where magnets can be used to hold light fixtures, display signage and create storage space. Visit our brochure here.

Our flexible sheets are very versatile and can be used in various customer applications to provide an instant fixing. See our steel container magnetic solutions as one example.
