Absolutely loved the products! The quality exceeded my expectations and shipping was incredibly fast. Will definitely be ordering again.Sarah Johnson
Description
SFXC Liquid Crystal Sheets – Precision-Calibrated are professional-grade thermochromic sheets designed for accurate thermal visualisation and colour-changing temperature mapping.
Also referred to as liquid crystal temperature sheets or thermochromic temperature film for precision thermal mapping applications.
Supplied as standard with a factory-applied adhesive backing, these sheets are designed for direct application to surfaces, making them suitable for both testing and permanent installation.
Available in selected sheet sizes, these heat sensitive liquid crystal materials display precise colour transitions across defined temperature ranges, allowing reliable interpretation of surface temperature distribution in laboratory, engineering, production, and specialist visual applications.
Used for: thermal mapping, surface temperature analysis, airflow visualisation, product testing, monitoring, special effects, and R&D validation.
Choosing a Temperature Range
The first three temperature ranges are our core options and are the most suitable starting point for many monitoring and visualisation applications.
Not sure which temperature range to choose?
Choosing the wrong range can result in little or no visible colour change.
Test first with our 7-Sheet R&D Evaluation Pack.
Includes £20 credit towards your full-size sheet purchase.
£20 credit is issued per evaluation pack purchase and may be used once against a full-size sheet order.
Recommended for first-time users and applications where the exact temperature range is unknown.
Available Sheet Sizes
- 450 × 300 mm — Continuous surface coverage and professional applications
- 300 × 225 mm — Smaller test areas and installations
- 225 × 150 mm — Evaluation and demonstration use
Available Temperature Ranges
Core Ranges (Stock Items – All Three Sizes Available):
- 20–25 °C
- 25–30 °C
- 30–35 °C
Extended Ranges:
- 29–33 °C — Currently available from stock in all three sizes
- 35–36 °C — Custom order (contact us)
- 35–40 °C — Custom order (contact us)
- 40–45 °C — Custom order (contact us)
35–36°C, 35–40°C, and 40–45°C ranges are typically supplied as full sheets (450 × 300 mm) with a minimum order quantity. Please contact us to confirm availability, lead time, and suitability.
Adhesive Backing
Sheets are supplied with a pressure-sensitive adhesive backing as standard, allowing direct application to clean, smooth surfaces for stable and repeatable thermal readings.
Non-adhesive versions are also available on request for applications requiring temporary placement, repositioning, or integration into assemblies.
Understanding Colour Change
Liquid crystal sheets display a reversible colour change across a defined temperature bandwidth, transitioning through a visible spectrum that allows interpretation of surface temperature distribution.
