Overview

Visualize Surface Pressure with Fujifilm Prescale Ultra Low Film

Fujifilm Prescale Ultra Low (LLLW) film is a unique pressure indicating sensor designed to reveal surface pressure distribution between mating surfaces. This thin, flexible film instantaneously changes color in response to pressure, providing a detailed pressure map for various applications.

Specifications:

  • Type: Pressure Indicating Film
  • Pressure Range: 28-85 PSI (2-6 kg/cm²)
  • Film Dimensions: 16.4 ft. x 10.6 in.
  • Feature: Instantaneous Color Change
  • Applications: Heat seal planarity, roller set parallelism, object impact, lamination press, heat sink pressure, bolted interface pressure, clamping forces

Key Features

Characterize surface pressure between any two mating, touching, or impacting surfaces. The dimensions of this film are 16.4 ft. x 10.6 in.

Prescale provides a surface pressure “map” that illuminates actual pressure magnitude (in precise PSI or kg/cm^2) and distribution between your two surfaces. The pressure range of this film is 28 - 85 PSI (2 - 6 kg/cm²)

Prescale reveals the contact surface pressure by virtue of a color change. This color change is instantaneous (less than a millisecond) and permanent

Prescale comes on a roll, is super thin, and can easily be cut from the supplied roll with scissor or laser to your precise application requirement

The color intensity of the film is directly related to the amount of pressure applied to it

All films guaranteed to have 18 months of shelf life available.

Pros & Cons

👍 Pros

  • Enables the characterization of surface pressure between any two mating, touching, or impacting surfaces with precision
  • Provides a clear surface pressure “map” that quantifies actual pressure magnitude in PSI or kg/cm² and distribution
  • Offers an instantaneous color change upon pressure application (less than a millisecond), providing immediate visual feedback
  • The color change in the film is permanent, allowing for post-event analysis and record-keeping
  • Comes on a super-thin roll, allowing for easy customization by cutting to precise application requirements with scissors or laser
  • The intensity of the film's color is directly correlated to the amount of pressure applied, offering quantitative measurement
  • Guaranteed to have an 18-month shelf life, ensuring long-term usability and readiness for various projects
  • Its dimensions of 16.4 ft. x 10.6 in. provide a substantial amount of film for multiple or larger applications

👎 Cons

  • The pressure range of 28 - 85 PSI (2 - 6 kg/cm²) is specific and may not be suitable for applications outside this range
  • Requires visual interpretation of color intensity to determine pressure, which might introduce some degree of subjective error without digital analysis tools
  • While providing a "map," the film does not offer real-time digital pressure readings without additional equipment
  • The film's dimensions, while generous, might require careful handling and cutting for very intricate or small-scale applications
  • Once used and changed color, the film cannot be reset or reused for a different pressure measurement
  • Storage must be managed to maintain the 18-month shelf life, as environmental factors could potentially affect its sensitivity
