CoolPax™ is our Phase Change Material (PCM) cooling technology. It uses a non-toxic carbon-based liquid that freezes at 58F/14°C and remains at that temperature for 2-3 hours.
Simply place CoolPax™ inserts in freezer or ice water for 35/40 minutes and insert into garment pockets.
Phase change material (PCM) is a non-toxic, carbon based material, with a high heat of fusion. Simply put, PCM absorbs heat as it changes from solid to liquid PCM is classified as latent heat storage (LHS) unit. TechNiche uses phase change material for cooling through our CoolPax™ technology.
