KulKote® works by using multiple Phase Change Materials (PCMs) that activate at a variety of temperatures and water-based polymers that have temperature regulating characteristics. As body heat comes in contact with KulKote, the PCMs begin absorbing and releasing energy based on their specific melting points. As the PCMs absorb heat, a cooling effect is created. As the heat source is removed, the heat energy is released. This continuous cycle manages temperature 24/7 to increase comfort for the life of the product.
