Super absorbent polymer (SAP)is functional polymer, it can absorb hundred times of its own weight of water in a short time, can absorb & release repeatedly. It’s non-toxic granules capable of absorbing and retaining many times their own weight in water. SAP is a unique surface cross-linking chemistry which prevents gel-blocking and allows liquid to flow freely to the particles for efficient absorption.

In addition to providing excellent moisture control, they thicken fluids and turn them into a solid gel, swell when in contact with liquid, and exchange ions during absorption. Why choose potassium based SAP (KSAP)?

For agriculture use, potassium based SAP is strongly recommended, as sodium based might rotten the roots and cause soil cake. Potassium based SAP is the optimal type for plant growth, it’s good for root, stems & leaves. 

Characteristics & advantages

* Potassium based

* Functional polymer, swells to a gel upon contact with aqueous fluids. * Nontoxic, no residue, can absorb and release water repeatedly. * Enhance soil's water-absorption, water-holding and nutrient preserving capability. 

* Increase soil coacertate & structure, increase soil's water absorption & soil moisture. * Enhance soil water-holding capacity & nutrient preserving capability. 

* Water save up to 50%

* Increase output & profits obviously. * Perfect match of fertilizer & pesticides.

How to identify SAP is potassium based or sodium based?

1) Identify product type

For agriculture use, please pay much attention to those sodium based SAP for disposal use, which is sodium polyacrylate product and degrade very fastly,as per the chemicals structure.

1) Identify the quality

Although both are co-polymers, but it exists potassium and sodium based types, sodium based is much cheaper than potassium based and it can rotten the plant roots and caused soil cake. Potassium based is for agriculture use only, it’s good for plant growth. Also, the cross-linking agent is different during polymerization, the less cross-linked typed with high absorbency rate, but with worse release performance and weak gel strength. Also the raw material purity and ratio & polymerization technology are essential for the product quality.

2) Identify the supplier

Fully check manufacturer’s production technology, raw material purity, solid content etc, ask samples to do the compared testing.

3) Do grass seeds germination test

To check SAP product is potassium based or not, the simple way is to do the grass seeds germination test, steps as belows:

1) measure 1g SAP sample, put it into 110g tap water within 10minutes it will be hydrated to water gel.

2) measure 1g grass seeds, put them on the surface of the water gel.

    3) after 4-7 days, the seeds put on the potassium based SAP gel will be germinated. do the same with the compared sample.

Sodium based sample degrades fast, and no seeds germinated, seeds got rotten.
