SAP
Super Absorbent polymer (SAP) for diaper making
Super absorbent polymer (SAP) is a polymer material with good water absorption and water-holding capacity.
It can absorb water up to several hundred times of its own weight, and turn into natural gel from within seconds. SAP can be mainly divided into three major categories which are Hygiene grade, Agriculture grade and Industry grade.
The main uses of SAP are absorbing, retaining or to block liquid.
1)Application
Fast absorbing speed, high water absorbency under load, anti-cakes. Strong water retention capacity with well distributed particles
2)SAP for diaper
SAP for diaper has good permeability, strong absorptive capacity and maintenance ability. It will not happen to return infiltration phenomenon under a certain pressure.
