SAP Made in Japan for Baby Diaper Production
² Product Snapshot
Popular Japanese SAP for baby diaper raw materials
² Unique Characteristics
Japan made SAP has the excellent capacity to absorb liquids in baby diapers.
Hot sale SAP for baby diaper raw materials performs well in water retention.
High quality SAP can help save the usage of other baby diaper raw materials, such as fluff pulp.
Tips: How SAP works in baby diapers
SAP is typically used as the raw materials of baby diapers. It helps improve capacity for better retention in a disposable baby diaper, allowing the baby diaper to be thinner with improved performance and less usage of pine fluff pulp. The molecular structure of the polyacrylate has sodium carboxylate groups hanging off the main chain. When it comes in contact with water, the sodium detaches itself, leaving only carboxyl ions. Being negatively charged, these ions repel one another so that the polymer unwinds and absorbs water, which is attracted by the sodium atoms. The polymer also has cross-links, which effectively leads to a three-dimensional structure. It has high molecular weight of more than a million; thus, instead of getting dissolved, it solidifies into a gel. The Hydrogen in the water (H-O-H) is trapped by the acrylate due to the atomic bonds associated with the polarity forces between the atoms. Electrolytes in the liquid, such as salt minerals (urine contains 0.9% of minerals), reduce polarity, thereby affecting superabsorbent properties, especially with regard to the superabsorbent capacity for liquid retention. This is the main reason why diapers containing SAPshould never be tested with plain water. Linear molecular configurations have less total capacity than non-linear molecules but, on the other hand, retention of liquid in a linear molecule is higher than in a non-linear molecule, due to improved polarity.
