Phase change materials can absorb or release large amounts of heat at a constant temperature by changing their physical state (e.g., from solid to liquid or liquid to solid).
The most classic example is the melting of ice: when ice melts, the water temperature remains firmly at 0°C until the last ice crystal disappears, after which the temperature begins to rise. This phenomenon of "absorbing heat without rising in temperature, releasing heat without dropping in temperature" is called a "phase change."
Phase change materials use this principle to become "magicians" of temperature management. They act like an invisible "energy sponge," absorbing and storing heat when it's hot, and releasing heat when it's cold.
Based on chemical composition, phase change materials are mainly divided into three categories: organic, inorganic and composite Phase Change Materials.
They offer stable performance, are non-corrosive, have low supercooling, and can be used repeatedly over long cycles, making them the first choice for construction and home applications. They have relatively low thermal conductivity and often require a thermally conductive structure.
They feature high thermal storage density, good thermal conductivity, and relatively low cost, making them suitable for scenarios requiring rapid heat absorption/release or limited space (e.g., cold chain, electronic cooling). Formulation modifications address supercooling and phase separation.
These combine organic and inorganic PCMs with porous carriers (e.g. expanded graphite, aerogels, porous carbon). They leverage the strengths of each, offering high thermal storage, high thermal conductivity, no leakage, and stable form. This is currently the mainstream direction for high-performance PCMs.
Coolinno has successfully overcome the inherent defects of both material types through core technologies such as microencapsulation and adding nucleating agents, ensuring high thermal storage, high stability, and long life in practical applications.
This is the phase change process in most application scenarios. The material is shaped when solid, facilitating processing and installation; when the temperature reaches the phase change point, it partially becomes liquid, absorbing significant latent heat; upon cooling, it re-solidifies, releasing heat.
Coolinno addresses the industry pain point of "leakage after melting" in traditional solid-liquid PCMs by using micro-encapsulation technology to lock the liquid PCM within a micro-structure.
Traditional forms, suitable for building envelopes, offering large total thermal storage.
Fine powders produced via spray drying or adsorption technology. They can be directly mixed into dry-mix mortar for building materials, plastic master-batches, or 3D printing materials for easy and uniform industrial dispersion.
PCM core material is encased in a micron-scale polymer shell, forming individual "micro-units." They can be mixed into paints, plaster boards, textiles, or mortar without leaking and are easy to process. Suitable for applications like interior walls and constant-temperature textiles.
Millimeter-scale encapsulated particles with good flow-ability and strong leakage resistance. Commonly used for filling ceilings, hollow walls, floor cavities, or as fill for mattresses and pillow cores, offering both thermal storage and breathability.
Coolinno focuses on the R&D and application of high-performance phase change materials, providing comprehensive temperature control solutions ranging from industrial energy storage and cold chain logistics to building energy efficiency and daily wearables.
Utilizing the high thermal storage density of PCMs, Coolinno enables industrial waste heat recovery and peak-valley electricity price arbitrage. In industries like steel, chemicals, and power generation, PCM modules store waste heat from production processes and release it when needed for preheating, heating, or power generation. Coupled with the model of storing heat using off-peak electricity and releasing it during peak hours, it helps enterprises reduce energy costs.
Coolinno offers medium-to-high temperature ( 42°C - 306°C ) PCM energy storage solutions, with forms including thermal storage bricks, capsule packed beds, and modular storage tanks, meeting diverse industrial scenario needs.
Coolinno's highly stable cool storage agents (-80°C to 12°C) offer greater thermal storage and longer constant temperature maintenance than traditional ice packs, ensuring uninterrupted protection for vaccines and fresh produce.
Coolinno products like PCM constant-temperature wallboards, PCM blankets, PCM microcapsule coatings, powder admixtures, and PCM capsule particle fill layers are particularly suitable for "passive houses" in green building.
Compared to traditional building materials, PCMs have a thermal storage density more than 10 times higher. A thin layer can replace some traditional, heavy thermal mass, increasing indoor thermal inertia without increasing wall thickness, further reducing reliance on active heating/cooling systems. This helps "passive houses" achieve passive constant temperatures, significantly lowering air conditioning energy consumption.
Coolinno's PCM cooling vests (for occupational heat protection) help workers in special operations such as coal miners, electrical workers, and firefighters effectively cool their core body temperature, delay fatigue, and improve work efficiency and safety.
Coolinno embeds PCM micro-capsules into fibers or coats them onto fabric surfaces, giving textiles bidirectional temperature regulation. When the body surface is too hot, the micro-capsule core absorbs heat and melts, providing a cooling sensation; when too cold, the core solidifies and releases heat, providing warmth. This technology is applied in smart clothing, bedding, shoe linings, etc., creating a "wearable constant temperature system."
Phase change materials are one of the key green energy technologies of the 21st century. Adhering to the philosophy of "Technology, Nature, Low Carbon," Coolinno is committed to using less energy to create more comfortable temperatures.
Making every kilowatt-hour of electricity more valuable, returning every space to its natural temperature – Coolinno walks with you.
