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. The paper is sourced and supplied by Science Lab Supplies from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each pack contains 40 sheets of A4 thermochromic paper. The sheets come in four colour combinations – blue/white, purple/pink, pink/white and green/yellow – where 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 marks the paper through them.
- Showing heat conduction along a metal strip or spoon placed on the sheet.
- 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 specification does not state how many sheets of each colour a pack holds; 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. For a quotation, reach the team through the contact page, build a list in the enquiry cart, or see the lab tender page for tender supply.
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.
Who supplies the Heat Sensitive Paper?
Science Lab Supplies supplies this paper from Ambala, India, and quotes it alongside its other physics items on a single quotation.
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.
Related Heat and Temperature Equipment
These four items extend the heat lesson that thermochromic paper begins: measured temperatures, a full insulation study, radiation from different surfaces, and conduction in different metals, 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.
- Thermal Insulation Apparatus — felt pads and a 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.
