Description
Testex Press-O-Film X-COARSE Grade Tape, 50 impressions per roll Range When Used with Gauge: 1.5-4.5 mils (40 to 115 microns) Press-O-Film (POF) consists of a layer of crushable plastic microfoam coated onto a polyester film of highly uniform thickness. When compressed against a roughened material, Press-O-Film accurately replicates details of its surface roughness.
Testex is the manufacturer of Press-O-Film replica tape. Press-O-Film provides inspectors and researchers a simple way to obtain an impression of a surface. Testex replica tape can be used with a Testex gage to measure the surface roughness ("profile") of blast-cleaned steel in the roughness range 0.8 to 4.5 mils (or 20 to 115 micrometers). Because inspectors, as a rule, have a target profile in mind. it is always best to start measurements with the grade of tape that has the target profile closest to the center of it's range.
