Flexible Magnetic Strips & Sheets

Bend it. Twist it. Cut, slit, punch, drill, or stamp it.

Bunting® Flexible Magnetic Strips conform to irregular shapes and provide holding power superior to conventional magnets on uneven metal surfaces. You can cut or form them easily without cracking or loss of magnetic energy. They’re light in weight and can be removed, reused, bent, or twisted again and again. Their flexibility and magnetic strength make them ideal where rigid, brittle, or electrically conductive materials can’t be used.

Applications include latches or catches, gaskets, door seals, tool holders, and holding fixtures. For signs, charts, displays, shelf labeling, and novelties, they’re a reusable alternative to adhesive or fasteners. They can also be used in switches or sensing devices or to dampen noise and vibration.

Bunting® Magnetic Strips are sold by the foot, so you can order exactly what you need. Perhaps best of all, they cost less than most other magnetic materials. And our large, centrally located inventory ensures that what you need will be in stock for immediate shipment.

Custom Fabrication Services

Bunting® Magnetics Co. can convert Flexible Magnetic Strips to meet your requirements.

Custom Slit-To-Width

If you don’t find the width of magnet you need from our stock inventory, Bunting® can slit Flexible Magnets of various standard thicknesses to the widths indicated in the chart at the right. Refer to this chart to select the right magnet thickness for the strip width you require.

Custom Cut-To-Length

Bunting® can cut or score Flexible Magnetic Strips to your specifications. Refer to the diagrams below to select the cutting or scoring method you prefer.

Magnetic Strip Cutting Capabilities

CP Cut Part
Cutting blade severs all substrates. Strip is cut into individual pieces.

CTM Cut Through Magnet
Cutting blade cuts completely through magnet and PSA adhesive but leaves the PSA liner intact. Cut pieces are peeled from the liner.

STM Score Through Magnet
Cutting blade cuts 3/4 of the thickness of the magnetic strip. The strip can be broken into cut pieces by bending at the score.

STP Score Through Paper
Cutting blade cuts PSA paper carrier, adhesive layer, and penetrates 3/4 of the thickness of the magnetic strip. The strip can be broken into cut pieces by bending at the score.

STV Score Through Vinyl
Cutting blade cuts colored vinyl top coating and penetrates 3/4 of the thickness of the magnetic strip. The strip can be broken into cut pieces by bending at the score.

Magnetization Patterns

Magnets with a conventional magnetization pattern have a single, equal strength pole on each opposite face.

Magnets with a multipole magnetization pattern on both sides have multiple poles along both faces. The magnetic force is of equal strength on both sides.

Magnets with a two-pole or multipole magnetization pattern have two or more poles on one face of the magnet. This pattern creates a greater concentration of magnetic strength on that face.

Adhesives

Bunting® can laminate Flexible Magnetic Strips with a variety of adhesives. See below for more information.

Adhesive options

PSA-HR: High-performance rubber-based, pressure-sensitive adhesive custom formulated for use with magnetic strip material. It has good adhesion and high initial tack qualities. High temperatures and plasticizers can soften this adhesive.

PSA-AC: General-purpose acrylic-based, pressure-sensitive adhesive that resists moderate amounts of plasticizer in plastics and PVC. Greater temperature and chemical resistance than rubber-based adhesives. Acrylic-based adhesives have lower initial tack but higher ultimate performance after a cure time of 24 hours. This adhesive is available on special order only and is not normally stocked.

PSA-F: High-performance acrylic-adhesive custom formulated for use with magnetic strip material. Adhesive features 1/32” thick polyethylene foam and is recommended for use on rough or irregular surfaces. This adhesive is available by special order only and is not normally stocked.

Vinyls

Bunting® can laminate Flexible Magnetic Strips with vinyls. White vinyl is standard. Red, orange, yellow, gold, black, blue, green, and silver vinyls are also available for larger custom runs.
