Potassium Polyacrylate, Potassium based super absorbent polymer for sale at best price

Potassium Polyacrylate is a Potassium based super absorbent polymer(SAP), it is an economical & best water-absorbent material. It has the features of Non-toxic, harmless, and Nonpolluting, but keep indirect contact.

Potassium Polyacrylate is The Right powder SAP super absorbent polymer for Agriculture, which helps you to continue farming even in not good conditions and get a better harvest.

An important difference between sodium polyacrylate and potassium polyacrylate is: Potassium polyacrylate will not saline soil, will not cause soil salinization.

The reason is that most plants, no matter crops or vegetables, flowers, their growing need NPK at balance, Nitrogen, Phosphorus and Potassium(Kalium), they need little Sodium(Na+), if the dose of Sodium polyacrylate exceed normal and sodium salt will be accumulated in soil and harm plants, cause soil salinization;

What is Potassium Polyacrylate?

Potassium Polyacrylate(Hydrogel) is a Potassium based super absorbent polymer, it has good water absorption and water-holding capacity (hundred times of its own weight) and turns to be water crystals when absorbs enough water.

SAP Powder Potassium Polyacrylate is in great demand in almost all countries/areas, such as North America,  China, India, Japan, Australia, Indonesia, Malaysia, South Korea, Brazil, Mexico, South Africa, Saudi Arabia, UAE, Kuwait, etc., please contact for details and factory prices before buying.

What is potassium polyacrylate uses, Application?

SAP Potassium polyacrylate for agriculture is an important use, it has the ability to retain & Release-control of Soil moist, Water & Nutrients for Plants in Farm or Garden, etc.

Potassium polyacrylate as an Agriculture SAP Super absorbent polymer, it can guarantee the growth of crops in drought & arid areas, and it can also save irrigation in non-arid areas.

Potassium polyacrylate has many other applications in many industries of Agriculture,

field crops,Transplanting of trees,vegetables,horticulture,lawns,greening project,SAP with fertilizer, etc.

how to make potassium polyacrylate?

Potassium Polyacrylate is made by the reaction between acrylic acid (H2C=CHCOOH) and its Potassium salt (H2C=CHCOOKa), or the reaction between Poly(acrylic acid) ([H2C=CHCOOH]n) and Potassium hydroxide (KOH).

  • CAS:25608-12-2;
  • Density: 0.4 g/mL at 25 °C (lit.);
  • SMILES string: [K+].OC(=O)C=C.[O-]C(=O)C=C;

So we also call it Potassium polyacrylate, Poly(acrylic acid) partial potassium salt, Poly(acrylic acid) potassium salt, K-PAM;

There are also other ways to produce Potassium polyacrylate.

How Does Potassium Polyacrylate Work?

The polymer consists a set of polymeric chains that are parallel to each other and regularly linked to each other by cross-linking agents, thus forming a network. When water comes into contact with one of these chians, it is drawn into the molecule by osmosis.

Water rapidly migrates into the interior of the polymer network where it is stored, and sap becomes water crystals. As the soil dries out, the water crystals polymer releases up to 95% of the absorbed water into the soil for plants.

  • Increases the water holding capacity of soil
  • Effectively reduces irrigation frequency
  • Reduces fertilizer usage by 25 - 35%
  • Improves the soil physical properties by enhancing aeration

Potassium Polyacrylate for Agriculture plants

Potassium Polyacrylate is effective in the planting of trees, it makes it possible to reduce the mortality rate due to transplanting shock and to enhance root development.

Potassium Polyacrylate can prolong the growth cycle of lawn and turf. Promote root development, increase germination rate and reduce irrigation times.

Potassium Polyacrylate is commonly used in hydroseeding to stabilize newly graded soils. Mixed with or without cellulose mulch. There are no dry spots without grass.

Potassium Polyacrylate can make the mud dip in the root, reduce the evaporation of water in the root, transplant with transportation, and improve the survival rate.

Potassium Polyacrylate improves soil water holding capacity is to improve plant growth, promote root development and reduce the number of watering.

The behavior of plants fertilized with Potassium Polyacrylate mixture makes it possible to maintain or even increase yield while at the same time protecting the environment from leaching.

Potassium Polyacrylate can increase the plant available water holding capacity, aeration balance and structure of soils, substrates and potting mixes.

Potassium Polyacrylate can absorb animal excrement, keep the environment dry, remove odor, defecate and manage. Increase the fertility of feces.

Potassium Polyacrylate in the form of hydrogel or water crystals for plants may be placed in sealed plastic pouches.
