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 become a natural gel within seconds. Even under the conditions of heat and pressure its water retention is also very strong. Meanwhile, it has a good stability when meeting light, heat, acid and alkali, also with good biodegradability. Because of its many advantages, SAP is widely used in various fields (personal care, agroforestry, industry, etc.).

Application & Advantages

Applications
Hygienic Grade SAP, Up to now, it has mainly been used in hygienic products (such as sanitary napkins, diapers, nursing pad and pet pad ect.).

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.
SAP for Lady Sanitary Napkin
SAP for sanitary napkin has fast suction of blood, high absorption capacity, good gel strength and moisture resistance. According advanced production technology, SAP is non-toxic, no smell and no stimulation to skin. The strong absorption capacity and water retention ability in women`s sanitary napkin can keep dry and comfortable.
