Business Dynamics
Phase change materials (PCMs) are latent heat storage compounds—ranging from organic paraffin waxes and bio-based fatty acids to inorganic salt hydrates—that absorb or release substantial thermal energy when transitioning between solid and liquid states at specific temperatures. In 2026, cold-chain logistics networks are widely integrating microencapsulated bio-based PCMs into insulated shipping totes to transport temperature-sensitive biological medicines safely without requiring heavy active refrigeration. Building product researchers are also introducing specialized PCM layers directly into drywall panels, allowing the material to absorb excess ambient heat during peak daylight hours and release it at night, lowering reliance on mechanical HVAC cooling loops.
