SAP ---Super Absorbent Polymer for diaper production
Super absorbent polymer can be used in many aspects, such as: Disposable baby diapers, Nappy, Incontinent underpads and other.
It is a green and environment- friendly high-tech product. It can be completely biodegradable into water, carbon dioxide and other small molecules under certain conditions.
Main Features
1). Absorb quickly, and it is easy to melt in blood and blood plasma
2). When melting in blood, its speed can reach 3-5ml per minute and 7-8ml per three minutes. It can resolve the blood leakage, especially for the thinner sanitary towel's leakage problem.
3). Good liquid penetrating character, and after absorbing, it is easy to dry.
4). It can be used for farm and forestry, saving water for farm and garden and improving trees' surviving ratio.
5). Used for sand, can help the plant absorb water.
Popular Japanese SAP for baby diaper raw materials
Unique Characteristics
1. Have the excellent capacity to absorb liquids in baby diapers.
2. Performs well in water retention.
3. 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 SAP should 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.
