FUJIFILM Prescale LW,LLW film compressive pressure measurement 0.5MPa～2.5MPa

Producer: SEMIKI

Category: Mechanical force gauge Tag: fujifilm prescale

FUJIFILM Presacale LLW is a line of pressure measuring films designed for use in high temperature conditions: Measure pressure where heat and pressure are applied simultaneously easily
Prescale for high temperatures
Prescale allows you to easily measure pressure distribution and range.
However, when conventional Prescale films are used for processes where heat is applied, this heat can lead to problems such as incorrect color development and substrate deformation. Prescaling for high temperatures significantly reduces these effects.

With effect codes with lengths such as LLW270X5m (5m long), LLW270x6m (6m long)...

You can contact Semiki to order according to the desired length.

Pressure measurement film

Prescale for High Temperature LLW

Prescale for High Temperature: Pressure measurement film for use under high-temperature conditions.

Super Low Pressure Two-sheet Type

Pressure measurement film designed for use under high-temperature conditions: Measure pressure in cases where heat and pressure are applied simultaneously with ease

Prescale for High Temperature
Prescale allows you to easily measure the distribution and range of pressure.
However, when regular Prescale films are used for processes in which heat is applied, this heat can lead to issues such as incorrect color development and base deformation. Prescale for High Temperature significantly reduces these effects.

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

Structure of Prescale

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.

How Prescale works

The microcapsules in the color-forming layer are broken by pressure, and the colorless dye is absorbed into the color-developing layer. This causes a chemical reaction, which produces a red color.

Pressure chart

The pressure value can be confirmed visually by referring to a standard chart.

Specificaiton:

Product name / Model : Prescale for High Temperature LLW

Size: 270mm×6m

Supported pressure measurement range: 0.5MPa～2.5MPa

Recommended temperature of applied heat: 180°C to 220°C (heat applied to both sides)

Precision: ±10% or less (measured using a densitometer)

Unit Conversion:

1 MPa = 1 N/mm² ≒ 10.2 kgf/cm²

To obtain the pressure value, you need the mass (kg) or newtons (N), as well as the surface area (mm² or cm²). For instance, if 100 kg is applied on a 100 mm² (1cm²) surface, the calculation is 100 kgf/cm². Divide this value by 10.2. The formula is 100 kgf/cm² / 10.2 = 9.8 MPa
