However, some experts are suspicious whether this chemical is safe or not for ice pack production. Thus, it is advisable not to overuse ice pack with this chemical. To know more if certain chemical may be dangerous, read Harmful Chemicals in the Environment. Sodium polyacrylate is the sodium salt of the chemical compound polyacrylic acid. This chemical is widely utilized in consumer products. Also, this chemical belongs to polymer that is super absorbent in water mass.
This makes the chemical a favourable choice for product sealing. In ice pack, sodium polyacrylate function as the gel container just like hydroxyletyl cellulose. Its absorption molecules make it an ideal seal for the ice pack. As a result, the gel ice pack becomes more flexible to use. Hence, sodium polyacrylate is one of the chemicals used in ice pack. While ammonium nitrate is common in old version of ice pack, the new modern version of ice pack also uses ammonium chloride.
Ammonium chloride is an inorganic compound with formula NH 4 Cl. The main use of it usually is for agricultural stabilizer and flavor agents. In ice pack, ammonium chloride also acts to trigger endothermic reaction. Ammonium chloride does not need great amount of water to produce cold temperature. It is also less dangerous than ammonium nitrate and is featured in the gel pack as well. Therefore, ammonium chloride is one of the crucial chemicals used in ice pack.
Silica gel is a common chemical to protect product from fungi and insect attack. It is considered to be the best and most common protector. The composition of silica gel consists of granular, porous, vitreous and silicon dioxide.
The chemical is also beneficial to control the humidity of a product in a closed seal. The silica gel comes with many types but the function is all similar.
In ice pack, silica gel is commonly found in gel ice pack where the gel of it contains silica gel. Properties of Hydrates for Chemistry Experiments.
