Plastic bonded
Plastic-bonded ferrite is a flexible material that can be punched or cut to the desired shape. The materials adapt well to arched surfaces and are therefore excellent for signs, decals for cars, etc.
A distinction is made between anisotropic and semi-anisotropic materials, where the latter have only one magnetic side. Tapes are usually semi-isotropic, while sheets and extrusions are available in both designs.
