How Sutrin Phase Change Material Works
Revolutionizing Thermal Control Through Advanced Phase Change Fabric
At the core of Sutrin’s innovation lies the power of Phase Change Materials (PCMs) — substances that absorb, store, and release large amounts of energy during their transformation from one state to another, typically solid to liquid and back again. A classic example is ice melting into water: at 0°C, the ice absorbs a substantial amount of heat (known as the latent heat of fusion) without changing temperature. This captured energy is released again when the water refreezes (latent heat of solidification).
But traditional PCMs, like water, must be contained in bulky bottles or pouches. Sutrin PCM changes the game.
Our revolutionary approach embeds the phase change material directly into the fibers of a flexible, moldable fabric — imagine millions of microscopic capsules working in harmony to manage heat. This patented design removes the need for containment vessels, offering a completely new way to integrate PCM into products and systems.
Even better, Sutrin PCM can be tuned to transition at virtually any temperature between -20°C and +100°C, making it highly customizable for your specific application — whether that’s keeping components cool in extreme environments or storing heat for wearable tech.

The Power Behind Phase Change Materials
Latent Heat vs. Sensible Heat Using Water to Explain— Why It Matters
To understand what makes Sutrin PCM so effective, we must understand the difference between sensible heat and latent heat.
- Sensible Heat is the energy absorbed or released by a material as its temperature changes.
- Latent Heat is the energy absorbed or released during a phase change, like when ice melts into water, without any change in temperature.
As an Example: Water and Ice
Let’s compare how much energy is absorbed in two different scenarios involving 1 kg of water:
Heating water from 0°C to 1°C (sensible) Sensible Heat 4.18 kJ
Melting ice at 0°C (latent) Latent Heat 334 kJ
This means latent heat absorbed (=energy) during the phase change (from solid to liquid) is roughly 80 times more than just raising the temperature by 1°C.
To match that energy with just heating, you'd need to raise the temperature of water by 80°C — and most materials can’t even handle that without degrading.
So a PCM absorbs, Stores and Releases very large quantities of energy
