Depending on the shape, flexible magnets are made by one of two processes–extrusion or calendaring.
Extrusion is used to form profile-extruded shapes that have irregular cross-sections, such as ridged magnetic strips.
This process squeezes a heated rubber magnetic compound through a die of the desired shape, producing lines of bubble-free, compact magnets.
Benefits to flexible magnets are wide versatility and their ability to easily mold around most shapes–at 20 degrees Celsius, they can be coiled into a 0.5” radius before cracking.
Working with flexible magnets is plain and simple you can pick up your household scissors since they can be sliced, drilled, punctured, scored, you name it. They are also heat-resistant up to 100 degrees Celsius.
Flexible magnets therefore available in these forms:
1. Plain bare Magnets
2. Printable, that is backed with vinyl and other substrates.
3. Adhesive form, that is backed with acrylic pressure sensitive adhesive.
Flexible magnets come in sheets pre-cut or rolls form.
JLP Company, Inc offers plain magnetic sheeting, which is pure, unadulterated magnetic material. Plain sheets are ideal for printers that have their own equipment and want to affix their own adhesive substrate.
come in a wide range of thicknesses and are available in two grades:
* Isotropic produced without magnetic orientation
* Anisotropic oriented using electromagnetic exposure to achieve higher strength
