SAP Super Absorbent Polymer for Baby Diaper Adult Diaper Sanitary Napkin
Raw Material for Baby Diaper Making SAP Powder MSDS Super Absorbent Polymer:
Super absorbent polymer (SAP) is a polymer materialwith 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.).
