isotropic hard ferrite, mixed with flexible plastic (PE) binder, reverse side with permanent adhesive, front side is magnetic, th = 0.6 mm, 20 x 30 mm, comes on silicone paper
An even more convenient method than our self-adhesive “MAGNETIC TAPE with dispenser” is to use these pre-cut magnetic tape “platelets” for furnishing photographs, posters or presentation charts with magnetic backing – these “Takkis” are also somewhat thicker. Their magnetic strength is similarly weak as that of the magnetic tape (as compared to NEODYMIUM MAGNETS!) but is strong enough to hold photographs, cardboard and lighter weight pieces of jewellery. It is important to note that these magnets must be attached to an even surface that is as flat as possible because their magnetic force will only work on such substrates, All the platelets are the same size which has the effect of looking very professional when compared to irregularly sized pieces just randomly placed on the back of something.
Once more for your information: these self-adhesive platelets are magnets; they only really work in conjunction with a counterpart like SHEET STEEL or FERRO SHEET or ferruginous (containing iron) MAGNETIC PAINT or the like serving as the adhesive receptacle,
The given adhesive strengths of the magnets are actually the removal force measured vertically to the adhesive surface at 21 °C. Serving as the adhesive surface was a ground steel sheet St 37 with a thickness of 5 mm. 10 N (Newton) strength is the equivalent of about 1 kilogram weight.
