A gel pcm pack is a flexible thermal control product filled with phase change materials dispersed in a gel matrix. Compared with rigid PCM cooling packs, gel packs offer improved flexibility and surface contact, making them suitable for applications requiring close thermal coupling and ergonomic design.
Gel pcm packs are widely used in cold chain transport, medical packaging, personal cooling products, and wearable thermal solutions.
Gel PCM packs store and release thermal energy through the latent heat of phase change. The gel carrier improves heat transfer efficiency and allows the pack to conform to surrounding surfaces, enhancing temperature stability.
| Temperature Range | Typical Applications |
