Pressure measurement film

Prescale for High Temperature HT 200 series

Model: HT 200 LW / HT 200 LLW / HT 200 LLLW

The Fujifilm Prescale for High Temperature 200 (HT 200) Series is engineered specifically for mapping contact pressure distribution under extreme thermal conditions. Standard pressure films warp or suffer from erratic chemical color development when exposed to extreme heat. The HT 200 series incorporates heat-resistant base materials and modified microcapsules to prevent base deformation and unintended ghost coloring up to 220°C.

Prescale for High Temperature ( HT 200 series) Pressure measurement film designed for use under high-temperature conditions: Measure pressure in cases where heat and pressure are applied simultaneously with ease

Measure pressure under heat conditions considering thermal effects such as thermal expansion.
Reduces the temperature adjustment time of pressing machine which improves inspection efficiency.

FUJIFILM Pressure measurement film “Prescale“ How to use Prescale two-sheet type

Thermal Expansion Compensation: Delivers authentic physical force mapping by discounting the expansion pressures generated purely by soaring hot metal/silicone dies.
No Heat Distortions: Eliminates crinkling or melting of the underlying film base during operations, reducing machinery downtime spent waiting for components to cool down.
Simple "Sandwich" Method: Cut Film A and Film C to fit your target zone. Place the rough, chemically coated faces facing one another between the dies and initiate your press cycle. The microcapsules shatter relative to localized force, spawning immediate vivid red impressions

Structure of Prescale

How to use Prescale for High temperature

Prescale comprises two films: an A film and a C film. The A film is a base material (PEN base) coated with a color-forming agent (microcapsules). The C film is a base material (PEN base) coated with a color-developing agent. The film is used by placing the sides coated with chemical agents in contact with each other.

Cut Prescale into any size or shape of your choice.

1. Remove the Prescale from the black and blue polyethylene bags and cut into the required shape.

Apply pressure and a color appears to where pressure is applied.

2. Place the color-forming agent of the A film and the color-developing agent of the C film together and put the Prescale in position for pressure measurement, with the C film on the bottom and the A film on top. Apply pressure.
