Heat Sensitive Paper
Product Code : LSK-PL-10326
Heat Sensitive Paper (SKU LSK-PL-10326) is a thermochromic paper that changes colour as its temperature rises, responding even to the warmth of a hand. It gives students a visual way to explore temperature, insulation and body heat in primary science, middle-school heat topics and Class 7–9 lessons. Packs can be ordered from Science Lab Supplies in Ambala, India, by schools, training colleges, tender contractors and distributors, on the same quotation as other heat apparatus.
Specifications
Pack size, sheet size and the four colour pairs of the thermochromic paper are tabulated below. In short, each pack holds 40 A4 sheets in blue/white, purple/pink, pink/white and green/yellow, and the colour shifts as the paper warms, making heat patterns visible without a thermometer.

Applications and Experiments for the Heat Sensitive Paper
Because the colour change follows temperature, the paper turns invisible heat into a pattern students can see and compare. A palm print, a warm beaker or an insulated cup placed on a sheet shows where heat flows fastest, supporting discussion of temperature, conduction and insulation.
- Class 7 science (heat): showing that the body is warmer than its surroundings.
- Comparing insulating materials by how quickly a warm object, such as a hot-water-filled Aluminum Calorimeter, marks the paper through them.
- Showing heat conduction along a metal strip placed on the sheet, before measuring it with the Apparatus for Changing the Thermal Conductivity.
- Body-temperature activities, such as comparing hand prints before and after exercise.
Standard Scope of Supply
One unit of Heat Sensitive Paper is a pack of 40 A4 sheets in the four colour combinations listed above. The split of sheets between the colours can be confirmed on the quotation; if you need a particular combination, mention it on your enquiry.
Packing, MOQ and Lead Time
You may request one pack or several packs for a whole year group, and every quotation states the packing, delivery time and price for the quantity requested. Thermometers and other heat and thermodynamics lab equipment can be added to the same quotation.
Registered as an exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. The number of packs for a year group can be given on the contact page or saved in the enquiry cart, and paper bought through a tender follows the lab tender page.
Frequently Asked Questions
How does heat sensitive paper work?
It is thermochromic: its colour changes as its temperature rises. Warmth as small as that from a hand is enough to produce a visible change on the sheet.
What colours are in the pack?
The paper is supplied in four colour combinations: blue/white, purple/pink, pink/white and green/yellow, in a pack of 40 A4 sheets. Each pair shows the colour change as the sheet warms up.
Who supplies the Heat Sensitive Paper?
A quotation for the thermochromic packs is issued by Science Lab Supplies in Ambala, India, and it can include the pack count, packing and dispatch alongside any other physics items on your list.
Can the sheets be cut for student groups?
Yes. A4 sheets can be cut into smaller pieces so that each group gets its own sample for hand-print or insulation activities, and one pack of 40 sheets then goes further across a class.
Related Heat and Temperature Equipment
These seven items extend the heat lesson that thermochromic paper begins: measured temperatures, an insulation study, radiation from different surfaces, conduction in different metals and expansion of a bimetal, so students move from seeing heat to measuring it with apparatus on the same quotation.
- Thermometer Set — liquid, digital and infrared thermometers for temperature readings.
- Digital Thermo-Hygrometer — 0–50 °C room temperature and humidity on a large-digit LCD.
- Thermal Insulation Apparatus — six felt pads and an air cell double-glazing panel for insulation studies.
- Heat Receiver / Leslie-Type Receiver — black and polished faces for heat radiation work.
- Conductivity Ring — copper, brass, steel and aluminium strips for comparing conduction.
- Conductometer, For Thermal Conductivity — five metal rods on a brass hub, with wax cavities at the ends.
- Bimetallic Strip — 200 x 15 mm brass and steel strip that curves when heated.
