STANDARD TOP PROFILE Denomination Dimensions % Land/void Characteristics & applications2 I L X i p SP106 25 5 4 5 10 40/60 3360 ribs/m2 Suitable for wide belt sanding calibrating machines. Excellent grip on materials and low strain strength of the raised profile SP108 20 20 4 8 40 49/51 1275 cells/m2 Instead of SP106 but with better calibration accuracy due to its higher resistance to deformation; good grip on materials, valid for machines provided with vacuum systems. SP109 15 15 4 7 22 49/51 2220 cells/m2 As an alternative for SP108 but with a higher land percentage: better strain strength and calibrating accuracy. SP110 10 10 4 5 15 49/51 5100 cells/m2 As an alternative for SP107 with a better grip on materials. SP111 12 12 3 7 24 60/40 2770 cells/m2 As an alternative for SP108 and SP109. Higher calibrating precision and a good grip. Suitable for vacuum systems. SP100 - - - - - - Ground surface, particularly valid for working on material of even less than 0,5 mm thickness.
