【Popular Science Tips on Polymers and Materials】--017 Popular Science Tips on the Materials Used in Baby Diapers + ljtjbx
Thread Content
Diapers for infants are made from a material called super-absorbent resin (abbreviated as polymer SAP), which is produced using starch and acrylate as its main raw materials. Diapers have poor breathability and inadequate heat dissipation capabilities. Whether using cloth diapers or paper diapers, it increases the temperature inside the scrotum. As for the skin area that uses diapers, healthy skin should be dry. Wet skin becomes fragile quickly and is prone to diaper rash. To minimize wetness caused by diapers, they should be changed frequently, and diapers with high absorbency should be used. If you use traditional diapers, you should check and change them more frequently. The main component of diapers is superabsorbent resin (abbreviated as polymer SAP), which is made from starch and acrylate as its primary raw materials. I won’t explain what starch is; there are many types of acrylates, and I’ve listed the toxicity tests for your reference. Comparison of the toxicity of several acrylate slurries: Name, State, Maximum tolerable dose in mice (mg/kg), Toxicity classification, Research institution. Acrylamide, powder: 150–180, moderately toxic; Acrylamide, liquid: 2000, low toxicity; Japan’s AC-400, liquid: 5000 (in rats), practically non-toxic; United States’ AC-MS, liquid: 2300, low toxicity; China Institute of Water Resources, Calcium magnesium acrylate gel: 15, >59160, practically non-toxic; Yangtze River Scientific Research Institute
Uh, diapers – you’ve explained those, so is the WSJ similar in that regard? :shut up:
What is WSJ an abbreviation for? I don’t know what this is called or how to popularize it Let me give a brief introduction.
I don’t know either; ask the person who watches the sea. It seems it can fly. . .

Diapers shouldn’t be worn for too long; generally, children can do without them by the age of 1. What’s really tested is an adult’s patience, as well as the child’s ability to develop good habits. When I was young, to extend the lifespan of diapers and prevent accidents, cotton fabric or non-woven material could be placed under the diaper and pulled out after use. Haha
I just had a baby; I went to check the ingredients of the diapers to learn something new
I wore diapers on the doll for such a long time without paying attention to the ingredients; go check it!
What exactly is this SAP acrylate? As far as I know, some diapers are made of polypropylene fibers
Some low-quality diapers are made from recycled pulp, which is very harmful to people.
