- No
Overview
Crosslink density decides the balance between how much an SAP absorbs and how firm its gel is. Lightly crosslinked polymer absorbs more but forms a soft gel; heavily crosslinked polymer absorbs less but keeps its shape under pressure.
For buyers with a defined target, Sarovar can develop a grade around it: a particle size cut for your dosing equipment, a retention level for your product, or a gel strength for your process.
Key points
- Particle size cuts from fine powder to coarse granules
- Absorption–gel strength balance tuned to your target
- Pilot lots for qualification before bulk supply
- Contract manufacturing and private label
