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.
