There are three defective sodium polyacrylate types. We can name them: yellow type defective, tiny particles type defective, and recycled type defective.
Yellow type defective
Yellow-type defective sodium polyacrylate would be produced when the temperature is over in the drying process.
Defects:
-The water absorption capacity is weaker than the common product;
-The color usually could be yellow or dark.
Tip: Some improved potassium polyacrylate (agriculture purpose) would also be yellow, dark, or black. There's a big difference between them.
Tiny particle type defective
Tiny particle type defective sodium polyacrylate would be produced by smashing & sifting process.
Defect
The tiny particle will weaken the liquid permeability which is important for paper diapers.
Recycle type
In normal conditions, recycled sodium polyacrylate is most used in wastewater control.
Tip: To earn more money, some profiteers would sell recycled sodium polyacrylate as common sodium polyacrylate.
