Short Description:

Neck Cooling Tube Wearable Cooling Neck Wraps for Summer Heat I Cold Gel Ice Pack | Reusable Neck Cooler Commute and Outdoor Activities | Relief for Hot Flashes or Fever The filling material of neck cooler is engineered phase change material (PCM). Both inorganic PCM and organic PCM have been used in this application product. Bio based normal paraffin PCM and bio based PCM are used as organic PCMs. A easy way to differentiate PCM type is by their density. Inorganic has a bigger density around 1.4 while 0.77~0.78 for normal paraffin pcms and 0.82~0.84 for bio based pcms.

There is no simple answer for this question. It depends on the applications and purpose and quality the client wants. Inorganic PCM has a good thermal conductivity but a short service life and it is very cheap. Organic PCMs are expensive in generally and especially for bio based normal paraffin which is best in its quality.
The inventor originally utilize bio based normal paraffin (Hexadecane for PCM18, Octadecane for PCM28) in his design. While at the moment, all kinds of PCMs are used in the market because the end user is lack of knowledge to choose the right PCMs. For example: by normal paraffin PCM, there is no "big hole" problem as other types of organic PCMs experienced.

PCM are not 100% pure in its ingredient, the foreign ingredient has smaller molecular than TPU, so they penetrate the film and hence it looks like sweating or white crystal after its duty cycle.

First of all, SenWo use high quality TPU with "zero leakage" film. Second, SenWo supplies bio based normal paraffin PCM but also bio based PCMs, so the client’s are to choose what they want. SenWo’s bio based normal paraffin are widely used in industry worldwide and by some world-famous companies. The PCM are ex tracted by renewable green resource and their latent of heat is over 220j/g in average which guarantee the neck cooler’s high performance.
