isotropic hard ferrite, mixed with flexible plastic (PE) binder, reverse side with permanent adhesive (without release paper), front side is magnetic, adhesive strength 0.12 N/cm², th = 0.35 mm, hand dispenser made from colourless, transparent polysterene, with metal cutting blade
This fairly thin self-adhesive magnetic tape can be used without the need of scissors or the bothersome fiddling with release paper as a means of furnishing the back side of photographs, posters, pages or other lightweight objects with magnetic strips that enable you to mount them on any magnetically appropriate surfaces (metal). These strips have the advantage that the magnetic surfaces that stick to the back are very thin and unobtrusive and will hold permanently. They can also be used together with whiteboards (which are almost always magnetic) and more modern magnetic presentation boards when the use requires the quick changing of moderation cards or the like. It is important to note that when using such comparatively weak magnets as these (see: NEODYMIUM MAGNETS) that they be attached to an even surface that is as flat as possible because their magnetic force will only work on such substrates. If there is not a completely flush contact area, the object for presentation will fall to the ground as if you had used an ordinary adhesive tape and you will look like a dope!
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.
