PCMs are organic and inorganic compounds that store and release heat as they melt and solidify at certain temperatures. It is decades-old technology based on centuries-old thermodynamics research into the nature of “latent heat.” Also known as latent heat storage, phase-change material has applications in many industries, from building products to bedding. The mattress industry uses microencapsulated phase change material technology in foams, fabrics, yarns and as topical applications.
