Technical Benchmark Matrix

Japanese Sumitomo & San-Dia SAP vs Generic Sodium Polyacrylate

Absorption kinetics, centrifuge retention capacity (CRC), and absorption under load (AUL) side-by-side.

Evaluation Parameter	Tingshuang Specification	Industry Conventional Alternative
Manufacturer	Sumitomo Seika (Japan) / San-Dia (Japan)	Commodity local monomer suppliers
Centrifuge Retention (CRC)	34 - 38 g/g saline solution	24 - 28 g/g saline solution
Absorption Under Load (AUL)	26 - 30 g/g under 0.7 psi pressure	14 - 18 g/g under 0.7 psi pressure
Rewet Value (3 Doses)	< 0.05g (Surface remains completely dry)	0.80g - 1.50g (Noticeable surface moisture)
Gel Blocking	Virtually zero gel blocking due to crosslink density	Severe gel blocking; fluid pools on surface
