Rubber Ferrite

Rubber bonded ferrite magnets are manufactured by mixing ferrite magnet info-icon powder and bonding synthetic rubber. In terms of strength and flexibility, they are excellent. Rubber ferrite products are formed by extrusion molding into various shapes such as sheets, boards, bars, or cylinders.
