SFXC Liquid Crystal Sheet R&D Evaluation Pack – 7 Calibrated Temperature Ranges

Avoid choosing the wrong temperature range.
Includes £20 credit towards your full-size liquid crystal sheet purchase.
£20 credit is issued per evaluation pack purchase and may be used once against a full-size sheet order.

Seven individually calibrated liquid crystal sheets for precise thermal evaluation, comparison, and selection.

The SFXC Liquid Crystal Sheet R&D Evaluation Pack is a professional-grade testing tool designed to help you identify the correct temperature range before committing to full-size liquid crystal sheets.

This pack includes seven precision-calibrated liquid crystal sheets covering a wide working range from 20°C to 45°C, allowing accurate comparison of colour response, sensitivity, and bandwidth across multiple temperature ranges.

Each sheet is manufactured using high-performance liquid crystal material and produced to defined calibration tolerances, delivering repeatable and interpretable colour response suitable for engineering, laboratory, and R&D environments.

Why use an evaluation pack?

Selecting the wrong liquid crystal temperature range can result in little or no visible colour change, making the material unsuitable for your application.

This pack allows you to test and compare multiple calibrated ranges before committing to a full-size sheet, reducing risk and avoiding unnecessary cost.

What’s included

  • Seven calibrated liquid crystal sheets
  • Temperature range coverage from 20°C to 45°C
  • Dimension of each sheet is 304.8 x 152.4mm (12"x 6")
  • Multiple bandwidths (1°C to 5°C) for comparison
  • Non-adhesive format for testing and repositioning
  • Designed for repeatable thermal analysis and validation

Format note: Sheets in this evaluation pack are supplied in a non-adhesive format to allow easy handling, repositioning, and comparison during testing. Full-size sheets are supplied with adhesive backing as standard, with non-adhesive versions available on request.

Temperature ranges & bandwidths

  • 20–25 °C — 5 °C bandwidth
  • 25–30 °C — 5 °C bandwidth
  • 29–33 °C — 4 °C bandwidth
  • 30–35 °C — 5 °C bandwidth
  • 35–36 °C — 1 °C narrow bandwidth
  • 35–40 °C — 5 °C bandwidth
  • 40–45 °C — 5 °C bandwidth

This combination allows comparison of sensitivity, resolution, and response characteristics across different temperature ranges, helping you select the most appropriate specification for your application.

Key performance features

  • High-performance liquid crystal material (not decorative or craft-grade)
  • Precision colour response across defined temperature bandwidths
  • Measured and repeatable Colour Play behaviour
  • Suitable for R&D, testing, validation, and demonstration work
  • Ideal for selecting the correct sheet before volume purchase

Next Step

Once you have identified the correct temperature range, move to full-size sheets for your application:
