How Long Does it Take to Recharge PCM Phase Change Material Cooling Packs?

Recharging times will depend on the type of PCM (phase change material). Not all PCM's are created equal.

ThermApparel uses a non-toxic bio-based PCM that out-preforms paraffin, salt hydrates, gel and ice in a number of areas.

Long term stability, safe handling, sourced from recyclable materials, won't get you wet or burn your skin. Our lightweight and flexible PCM cooling packs are reusable and can be recharged again and again and again.

The cooling packs will freeze in any environment under 70F / 21C. About 20 min in ice water, 40 min in the freezer, 60 min in the fridge 10-12 hours if left on a cold surface in a cold room under 70F / 21C. We have tested recharging in the snow and it took about 5 min. Please note all recharging times are approximate.

ThermApparel's UnderCool Cooling Vest works by using PCM (phase change material) cooling packs. PCMs are substances that absorb and release thermal energy during the process of melting and freezing. What does that mean? Simply, they act as a heat sink to absorb your body heat slowly over time to keep you cool and comfortable, even in humid environments.
