Abstract
1354598 Flexible magnetic laminate MINNESOTA MINING & MFG CO 11 Aug 1971 [12 Aug 1970] 37814/71 Heading B5N [Also in Division C1] A flexible magnetic laminate is made by adding acid-leached barium ferrite to a cis-1,4- polyisoprene rubber composition or to a polyamide on a banding mill, and repeatedly doubling over and rolling out the sheet. The ferrite particles are magnetically orientated by heating and then cooling the sheet in a magnetic field.
