Superabsorbent Polymer Applications

AuraChem supplies superabsorbent polymer solutions for challenging liquid waste streams, gel ice pack manufacturing and root-zone water management. We help identify the most suitable product series and application rate for each process and material.

Discuss Your Requirements How We Test

Liquid Waste Solidification

Superabsorbent polymers can be used to control free liquid and improve the physical consistency of sludge, slurry and other high-moisture materials. Product selection and application rate depend on the material chemistry, solids content, operating conditions and required outcome.

EPB tunnelling spoil in the North East Link spoil handling facility

EPB Tunnelling Spoil Solidification

EPB tunnelling produces variable, high-moisture spoil containing clay, fines and conditioning agents. The appropriate superabsorbent polymer helps control free liquid at the source, creating a more consistent material for loading and haulage.

Other Applications

Beyond liquid waste solidification, superabsorbent polymers support gel ice pack manufacturing and root-zone water retention.

Superabsorbent polymer powder and gel ice pack formats

Superabsorbent Polymers for Gel Ice Packs

SAP absorbs and immobilises water to create a smooth, consistent gel for reusable and single-use ice packs. The resulting gel limits free-liquid movement, supports even distribution throughout the pack and reduces leakage if the packaging is damaged.
