Phase change microcapsules are engineered small particles that can store and release heat at defined temperatures, making them a smart material choice for thermal control in chemicals, coatings, textiles, packaging and building materials. In essence, they behave like small thermal buffers, helping a product stay more stable as temperatures increase or decrease.
Their value to the chemical industry is the combination of material science, encapsulation chemistry and performance control into one functional ingredient. They are employed when improved thermal control is required without altering the core product design and are of particular interest for industrial and sustainable applications.
