Materials:

• Outer: HDPE plastic shell

• Inner: SAP/CMC/PCM

• SAP:
• (Super Absorbent Polymer, SAP) is a kind of new functional Polymer material, it does not dissolve in water, and insoluble in organic solvents, good dispersibility, avirulent insipidity, pressure dehydration, can use repeatedly, bibulous rate can be generated in dozens of seconds gel. It is personal hygiene items, industrial and agricultural production, civil construction and other fields are widely used.

• CMC:                                                                                                                             
• (Carboxyl methyl Cellulose, CMC) CMC is a kind of important Cellulose, is a natural fiber after chemical modification of a kind of water-soluble good polyanionic Cellulose compounds, soluble in hot and cold water, odourless, tasteless, non-toxic.Is a kind of macromolecular chemistry, can swell, swelling in water, can form gel transparent viscous liquid.

• PCM:                                                                                                                             
• Phase Change Materials (PCMs) are ideal products for thermal management solutions. This is because they store and release thermal energy during the process of melting & freezing (changing from one phase to another). When such a material freezes, it releases large amounts of energy in the form of latent heat of fusion, or energy of crystallisation. Conversely, when the material is melted, an equal amount of energy is absorbed from the immediate environment as it changes from solid to liquid.
