Fujifilm Prescale LLW R270 Super Low Pressure Film (Made in Japan):
- Technical Specifications: Pressure measurement range 0.5 to 2.5 MPa (5 to 25 bar / 73 to 363 PSI), roll dimensions 270 mm width x 5.0 meters length (R270 roll format), film type Two-Sheet Type (A-Film with microencapsulated color-forming agent + C-Film with color-developing developer agent), measurement accuracy ±10% or better (under calibrated densitometer conditions), operating temperature range 20°C to 35°C (35% to 80% RH), thickness approx. 100 µm per sheet, Product of Fujifilm Corporation Japan.
- Direct Visualization of Contact Pressure Distribution: Turns invisible mechanical contact pressure into clear magenta-red color density contours for instant visual evaluation of clamping parallelism.
- Ultra-Low 0.5 to 2.5 MPa Range: Perfectly calibrated to capture delicate nip roller pressures, LCD screen bonding, and precision semiconductor heat sink clamping forces.
- Micro-Encapsulated Color Forming Chemistry: Micro-capsules of varying diameters burst proportionally under applied pressure, creating a high-resolution magenta density gradient.
- Two-Sheet Separate Film Architecture: A-film and C-film mate face-to-face during testing to prevent premature color developing during cutting and handling.
- Quantitative Calibration Analysis: Color density can be compared against standard temperature/humidity calibration charts or scanned via Fujifilm FPD-8010E software for precise MPa contour maps.
- Applications: Heat sink contact pressure validation, LCD/OLED panel laminating roller nip measurement, PCB pressing, fuel cell gasket sealing, and automotive engine gasket inspection.
