| The flexible permanent magnetic sheeting has back coating on magnetic side. For purpose of smooth touch,high quality appearance and avoid blocking issues that are sometimes happen on long rolls of plain magnet or high stacks of sheets. Jasdi Magnet back coat our Isotropic flexible magnetic sheeting defaultly. Of course, non back coating are available also. COMPONENT JM-878 : STRONTIUM FERRITE(Sr0.6Fe 2 O 3 ) BONDED FLEXIBLE MAGNET.
