Why Buyers Test Absorption
Absorption ratio is the headline spec that drives cost and performance. A quick in-house check confirms a shipment matches its datasheet and helps you compare suppliers on like-for-like numbers rather than marketing claims.
Simple Gravimetric Test
Weigh a known dry mass of SAP, add a measured volume of water, let it swell to equilibrium, then drain and weigh the gel. Divide gained weight by dry weight for the multiple (e.g., 1 g swelling to 300 g means 300×). Repeat three times and average.
Factors That Skew Results
Salt, hardness, and temperature of the test water all change the number—use deionised water for a fair spec check and note conditions. Mixing method, swell time, and how thoroughly you drain free liquid also move the result.
Recording and Comparing
Log dry mass, water type, temperature, swell time, and drained gel mass for every batch. Compare only tests run the same way, and keep a reference sample so future shipments check against a known-good baseline. FLORPOLY shares full test methods with buyers.
