For the development of a new product we are looking for a material that can be kept at a certain temperature for minimum 1-2 hours. The minimum temperature range should be between 6°C and 25°C and preferably also useable in environments with high humidity. It needs to be safe, flexible and lightweight. Cooling can be activated by putting the solution in a fridge or freezer or cold water depending on the energy/cooling needed.
We need to be able to use it in clothing or apparel. At the moment we are already using a bio-based PCM technology that goes from liquid to solid at a fixed temperature and now are looking for something that can cover the blind spots we are facing with the technology we are using now.
