Sumitomo super absorbent polymer (SAP) used in disposable dog pee pads stands out from ordinary SAP for its superior absorption speed, liquid-locking performance, gel stability, salt resistance and safety. It is widely recognized as the premium material for high-end pet pads.
Its key advantages include:
Fast Absorption
Sumitomo SAP absorbs liquid rapidly, locking in moisture within just 3–5 seconds of contact and keeping the surface much drier than standard SAP.
Strong Liquid Retention
With high gel strength, Sumitomo SAP forms a stable structure after absorption and resists leakage even under moderate pressure. Ordinary SAP has lower absorbency and tends to leak once saturated.
Excellent Salt Tolerance
Electrolytes in urine can greatly reduce the absorption performance of standard SAP. In contrast, Sumitomo SAP maintains high absorbency for both urine and saline solution.
Safe and Reliable Quality
Sumitomo SAP has extremely low residual monomers, meets international hygiene standards, and is non-toxic and non-irritating for safe pet use.
