Getting Started

Whether you are looking for a common size and/or shape or require a completely custom configuration, the process of selecting a flexible magnetic strip starts the same way.  The steps below provide a way to specify your magnet or serve as a starting point for a quotation for a custom order.  You can order from our "Quick Ship" products in our On-line Store or Contact Us to help you select the right flexible strip magnet design an approach that works for you.  It all starts with a few key attributes below:

Step 1 - Magnetic Strip Material Options

Select Magnet Thickness & Width 

These basic parameters define the magnet's fundamentals and direct us toward the raw material required. 

Thickness
A range of thicknesses from 0.020(in) to 0.120(in) are available for Flexible Strip Magnets.

pole configurations2Pole Configurations

Standard Flexible Magnets are MultiPole Single Faced Magnetized.  The image to the right shows this configuration which is applicable to most applications (Multipole One Face).

Other options are available (to the right) for arranging the poles on a flexible magnet.  If your project calls for specific magnetization, Rochester Magnet can also accommodate this requirement.

AWESOME SOLUTIONS FOR SIGNS AND DISPLAYS!!!

Matched Pole Strip

Matched Pole strip is available for magnet face to face applications.  When a magnetic receptive surface is not available, Matched Pole allows face to face without the challenge of aligning poles. Contact us for details. See More at Solutions for Signs and Displays.

High Energy and Nitril Butile for "Special Applications"

Need more strength for your flexible strip?  - You may require a High Energy magnet.

Have a high temperature application or require chemical / solvent resistance? - Nitrile Butile Bonded Magnet may be right for your project.

Click to learn more about our High Energy and Nitrile Butile products.

FLEXIBLE - HIGH ENERGY

Offering a stronger level of pull force when compared to a comparable thickness of standard energy flexible magnet,  High Energy flexible is highly resistant to demagnetization and free from chipping or cracking, while allowing for ease of fabrication and handling.  High Energy flexible is available in adhesive-backed, vinyl laminate or plain material.

Both Standard and High Energy flexible are available in High and Low Modulus Binder. Maximum continuous operating temperatures—175° F (High Modulus), all other 160° F (70° C).Custom Profiles available.High Energy Strip and Sheet are available in a variety of energy levels. Please call so we can discuss your needs and specifications.

NITRILE BUTILE FLEXIBLE MAGNETIC MATERIAL

Versatile, high quality and economical all describe our Nitrile Butile based products.  Rubber bonded strontium ferrite flexible magnets can be bent, twisted and flexed without loss of their high magnetic energy.

Flexible magnet products are produced in three forms:

  • Ferrite Magnet Sheets
  • Ferrite Magnet Strips
  • Ferrite Magnet Die-Cut Shapes

The following value added options are also available:

  • Pressure Sensitive Adhesive
  • Vinyl laminations
  • Polarity Identification
  • Customized Formulations
  • Special Cutting Techniques

Nitrile Butile based magnet has the versatility of accepting several methods of magnetization.  The standard methods are conventional, two poles each side, and multiple pole.  Custom magnetization patterns are also available making them ideal for low cost position or speed sensing encoders.

These magnets are ideal for high temperature applications and are certified for most automotive applications including inside the engine, transmission, and differential components.

Contact us to learn more and discuss how we can create a product specific to your needs.

Quick Ship Available On-line

Step 2 - Adhesive Laminate Options

Select An Adhesive or Laminate

When selecting the right flexible strip magnet it is important to know that your application determines whether you need a pressure sensitive adhesive or other material laminated to the magnet. The options are identified below. 

Plain Adhesive Laminate
No Coating PSA: Rubber Vinyl: Matte White
No Laminate PSA: Acrylic WOWO
  PSA: Foam UV Matte White
    Vinyl: Colors

LAMINATE NOTE:
Application of vinyl to the magnet material can be provided alone or in conjunction with adhesive on the other side.
Six standard colors are available for vinyl lamination:
White, Black, Blue, Yellow, Red and Green

Fundamental Best Practices for Care and Application of Adhesives

 

Step 3 - Cut and Scoring Options

Select Length and Cut vs Score Options

Strips can be cut or scored to suit specific applications.  Cut strip is neatly boxed for individual piece use and storage.  

Scored material leaves the magnet intact on the adhesive and release liner.  One advantage to scored materials is that it is still in roll form and therefore easier to handle and store.  Simply remove pieces as needed without having to meticulously remove the liner.

flexibleStripCutThrough
Cut Through

The blade cuts clean through the magnet and the release/lamination to create individual pieces.

flexibleStripCleanScore
Clean Score

Through magnet and adhesive, yet not through the adhesive release liner.

flexibleStripPartialScore
Partial Score

Incomplete cut through magnet and are separated into individual pieces by bending them at the score line.

flexibleStripLaminateScore
Through Laminate

Allows separation of the release liner from the adhesive/magnet.

 
Custom

In addition, to the straight cut options identified above, we can custom die-cut in standard design or your specific shape.
