1. PRODUCT DESCRIPTION

2. TYPICAL PROPERTIES

3. MAIN APPLICATION AREAS

• Agriculture & Horticulture: Mixed into soil to store water and plant nutrients (especially potassium) and release them in a controlled manner.

• Afforestation & Landscaping: Applied to the root zone during seedling planting to increase survival rates.

• Liquid Waste Management: Solidification of aqueous sludges and medical waste.

• Hygiene Products: Absorbent core in baby diapers and adult incontinence products.

• Industrial: Water-blocking in submarine cable armoring, cooling gel packs, artificial snow.

4. RECOMMENDED DOSAGE

The application rate must be adjusted according to soil type, plant species, and climatic conditions. The values below are general recommendations:

Important Notice: The product must be thoroughly mixed into the soil depth (e.g., 10–20 cm). If left on the surface, it may cause slippery conditions or plant heaving upon swelling.

5. SAFETY AND HANDLING

• Hazard Classification: Not classified as a hazardous substance under current regulations.

• Risk Phrases: May cause mild irritation on contact with skin and eyes. Inhalation of dust may cause mechanical discomfort.

• Personal Protective Equipment (PPE): Use safety glasses and a dust mask when handling; wear gloves to avoid skin contact.

• Slip Hazard Warning: Forms an extremely slippery gel layer when spilled on wet floors. In case of spillage, sweep up dry; do not use water.

• First Aid:

  • Eyes: Rinse with plenty of water for at least 15 minutes.

  • Skin: Wash with soap and water.

  • Ingestion: If accidentally swallowed, rinse mouth with water and drink plenty of water. Never give anything by mouth to an unconscious person.

6. PACKAGING AND STORAGE

• Packaging: Double-layered moisture-barrier bags (inner PE, outer kraft paper or PP woven); available in 1 kg, 5 kg, and 25 kg packages.

• Storage Conditions: Store in a cool, dry, and well-ventilated area with packaging tightly closed. Keep strictly away from moisture, water, and heat sources.

1. SECTORAL SUITABILITY TABLE (By Particle Size)

Since potassium polyacrylate is a cross-linked polymer, its performance is defined not by a single molecular weight but by particle size (mesh range) , which determines absorption speed, gel strength, and the risk of gel blocking.

2. OTHER NAMES & SYNONYMS

This chemical is referred to by various names depending on the industry and intended use:

• Chemical / Generic Names:

  • Potassium Polyacrylate (IUPAC)

  • Cross-linked Potassium Polyacrylate

  • Polyacrylic Acid, Potassium Salt

  • Potassium SAP (Super Absorbent Polymer)

• Commercial / Sectoral Names:

  • In Agriculture: Water Retaining Polymer, Agri-Gel, Rain Gel, Hydrogel, Solid Rain

  • In Hygiene: Super Absorbent (SAP)

  • In Daily Life: Water Beads, Artificial Snow, Crystal Soil

3. APPLICATION RECIPES (Step-by-Step)

A. Subsoil Application in Agriculture (Field/Garden)
The most critical point is to mix the product dry into the root zone homogeneously with the soil.

1. Dosage Calculation:

   • Sandy soil: 2.0 - 2.5 kg / m³ of soil

   • Loamy soil: 1.5 - 2.0 kg / m³ of soil

   • Clay soil: 1.0 - 1.5 kg / m³ of soil

2. Pre-Mixing: In a container, mix the dry polymer with 5-10 times its volume of dry soil to create a "pre-mix." This prevents clumping.

3. Application: Spread this pre-mix over the planting area at a depth of 15-20 cm and work the soil to ensure homogeneous distribution.

4. Irrigation: Immediately after application, water generously until the soil is fully saturated. Once the polymer has swollen, you can water the plants much less frequently than normal.

B. Sapling / Tree Planting Recipe (Pit Method)

1. Place a small amount of loose soil at the bottom of the planting hole.

2. Dosage: Thoroughly mix 50 – 150 g of dry polymer per sapling with all the soil excavated from the hole.

3. After placing the sapling in the hole, fill around the roots with this mixture.

4. Important: Never allow the roots to come into direct contact with pure, dry granules; even when using pre-swollen gel, do not place excessive amounts right at the root collar.

C. Potted / Balcony Plant Recipe

1. Method 1 (Dry): Mix 1.5 – 2 grams of dry granules into 1 liter of potting soil. Fill the pot and plant.

2. Method 2 (Pre-Swollen – Recommended): Soak 1 gram of dry granules in 1 liter of water for 30 minutes to form a gel. Mix this gel with the potting mix at a ratio of 1/3 or 1/4. This method makes dosage control easier and eliminates the risk of over-swelling.

4. ALTERNATIVES

Alternatives to potassium polyacrylate are other synthetic or natural polymers that function as water retainers.

5. ALL ACRYLATE TYPES & COMPARISON TABLE

The three most common types of polyacrylate salts in agriculture and industry differ based on the alkali metal or ammonium ion in their structure.

Summary Selection Guide:

• If you are growing plants and want to improve the soil: Choose Potassium Polyacrylate without question.

• If you need to solidify industrial wastewater or manufacture diapers: Sodium Polyacrylate is the most economical and highest-capacity solution.

• If you need water retention combined with a nitrogen fertilizer effect: Ammonium Polyacrylate can be considered, but it is less common than the potassium type due to odor and stability issues.
