Abstract

The application of flexible magnetic rubber seals to slide fasteners to form pressure tight closures was investigated. Several configurations were fabricated using flexible permanent magnet strips of neoprene rubber loaded with barium ferrite. In an attempt to increase attractive forces, neoprene rubber was loaded with carbonyl reduced iron particles to increase magnetic permeability, but the material lacked adequate tear strength. Excess bulk and lack of flexibility constitute the most serious deficiencies. Leakage also was a difficult problem particularly with circumferential closures where bending caused rippling of the seal lips. The final and most successful design utilized magnetic rubber blocks cemented to the back of a flexible rubber strip for the inner seal. Further development will be required prior to application of magnetic seals to closures.
