When selecting a supplier of agricultural super absorbent polymer (SAP), it’s crucial to choose a reliable manufacturer of Potassium Polyacrylate. Making the wrong choice may lead to purchasing the incorrect type of SAP, which can result in poor crop performance or even soil damage.
Two Types of Super Absorbent Polymers
Super absorbent polymers mainly come in two types:
-
Polyacrylate de potassium
-
Polyacrylate de sodium
Though they may appear similar, their raw materials, pricing, and agricultural performance are significantly different.
Type | Raw Materials | Price (Approx.) | Main Applications |
---|---|---|---|
Polyacrylate de sodium | Sodium hydroxide, acrylic acid, etc. | USD 1,200/ton | Diapers, sanitary napkins, absorbent sheets |
Polyacrylate de potassium | Potassium hydroxide, acrylic acid, etc. | USD 3,000/ton | Agriculture, horticulture, landscaping |
Potassium Polyacrylate for Agriculture
Polyacrylate de potassium is a soil-friendly hydrogel specifically designed for agricultural applications. It absorbs water during irrigation or rainfall and forms a water-retaining gel. When the soil becomes dry, this gel gradually releases water to the plant roots.
Key features include:
-
Reusability: After releasing water, the gel reverts to its powder or granular form and reabsorbs water during the next rainfall or irrigation cycle.
-
Longevity: It remains effective in soil for 3 to 10 years.
-
Eco-Degradation: Gradually breaks down into potassium ions, water, carbon dioxide, and ammonia, benefiting the soil.
-
Improved plant health et reduced irrigation needs.
Due to its potassium-based composition, GELSAP™ Potassium Polyacrylate supports sustainable agriculture and enhances crop resilience in drought-prone areas.
Sodium Polyacrylate: Not Suitable for Agriculture
In contrast, Polyacrylate de sodium is primarily used in hygiene products such as diapers and sanitary pads. While it also forms a water gel, it does not release moisture to plants et degrades quickly when mixed with soil.
Worse still:
-
Sodium ions can cause soil compaction, reducing its aeration and harming root systems.
-
It provides no agricultural benefit and may damage the soil structure.
While its lower price may seem attractive, Sodium Polyacrylate should never be used in agriculture.
Beware of Imitations in the Market
Due to the significant price difference between potassium and sodium polyacrylate, some suppliers may sell sodium-based products disguised as potassium polyacrylate.
This makes it all the more important to partner with a trustworthy manufacturer.
