- Product Description
Anhydrous Solid Potassium Formate | High-Purity Industrial Solution for Drilling & Deicing Applications
SHANXI ZHAOYI CHEMICAL CO., LTD has made acetate salts since 1988. That is more than 35 years of production. Our manufacturing base covers 27,000 ㎡. Output holds steady at 150,000 tons a year. One main product we supply is high-purity Anhydrous Solid Potassium Formate (CAS 590-29-4, HCOOK). Purity is 97% or higher. The white crystalline powder dissolves without trouble. It takes up moisture in a predictable way. Crews at oilfields mix it into HPHT drilling fluid formulations. Density in those fluids can reach 1.57 g/cm³. It also goes into aviation deicing solutions. Those solutions work at temperatures down to -50°C. Another use is precision industrial chemical synthesis. We hold ISO certification. KOSHER and HALAL certifications are in place too. Buyers in Europe, America, and Asia have purchased from us for years. They stay because quality does not drift under our strict quality control systems.
Key Features & Benefits
Strong Thermal Stability
Performance holds steady under HPHT conditions above 200°C. Polymer breakdown during deep well drilling is held back. The rheology of the drilling fluid stays in balance. Downhole work can then go on safely and without interruption.
Non-Corrosive Formulation
Different from traditional chloride chemical products, our formula eliminates stress corrosion cracking risks. It provides reliable protection for high-value alloy equipment, greatly reducing equipment maintenance costs in oilfield exploitation and aviation deicing scenarios.
Rapid Dissolution Rate
The crystals are fine. They are uniform as well. In water, this product dissolves completely within minutes. Brine batching on site then takes much less time. Crews get more done, and field operating costs go down.
Environmental Compliance
This product biodegrades well. It also meets the North Sea PLONOR rules for offshore discharge in full. Strict environmental rules do not stop companies from running efficient production. Green production and efficiency end up in balance.

How It Works
Anhydrous Solid Potassium Formate works two ways at once. Tight ionic interaction is one of them. Control of osmotic pressure is the other. Once the material dissolves in water, the potassium ions it releases build a brine of high density. Pressure in the downhole formation is balanced by that brine, so the drilling operation stays stable.
For deicing, formate anions break up the structure of ice crystals at the molecular level. Dissolving gives off heat. That speeds up the melt of ice and snow. At the same time, potassium ions hold back a second freeze. Anti-icing therefore lasts a long time, even at -50°C.
Sodium ions get swapped out for potassium ions inside clay layers. Shale stays stable thanks to that swap. The clay particles lose water. Expansion and hydration of the shale get held back. Stability of the wellbore holds up through extended drilling over long distances.
Applications
Oilfield Drilling & Completion
For HPHT wells, this product is used to prepare completion fluids that are solids-free and high-performance. Reservoir formations do not get damaged. ECD control stays accurate. That setup ensures efficient and safe recovery of oil and gas resources.
Aviation & Highway Deicing
This eco-friendly ice control agent works on airport runways. Highways and bridge decks get the same treatment. Aircraft brake components face no corrosion from it. Concrete infrastructure stays undamaged. That makes it suitable for deicing high-standard public infrastructure.
Industrial Chemical Synthesis
Catalyst production uses it as a common intermediate. So do materials that adjust pH. Batch consistency stays steady. Because of that, pharmaceutical and agrochemical output runs at high precision.
Workover Operations
Build workover fluids that do no harm to the formation. Reservoir permeability stays intact that way. Hydrocarbon recovery climbs, and offshore platform operations get more economic value back.

Manufacturing Process
Continuous neutralization technology for Anhydrous Solid Potassium Formate is what our production line runs on. The raw materials are formic acid and potassium hydroxide, both high-purity. Reaction happens at a temperature we hold constant. After that comes multi-stage crystallization. Final product purity stays at 97% or higher.
We remove leftover moisture with multi-stage centrifugal separation. The moisture level stays strictly under 0.5%. Next, vibrating equipment screens the finished products. Particle size distribution comes out uniform. That maximizes how efficiently the product dissolves.
Our laboratory conducts real-time spectral testing and quality monitoring throughout the production cycle to ensure stable and consistent chemical composition of each batch of products, eliminating quality fluctuations.

FAQ
Q: When it comes to shale hydration inhibition, does this product work better than KCl?
A: A1: Yes. Osmotic pressure is stronger than with potassium chloride. Clay stabilization is also stronger than with potassium chloride. Shale hydration and expansion are held back. There is no risk of environmental pollution.
Q: What are the main storage rules?
A: A2: Store the product in sealed packaging and keep it in a dry warehouse. Keep relative humidity under 60%. Moisture gets into the product easily. Take firm steps to block moisture. That stops the product from caking.
Q: Does it work with standard polymer additives?
A: A3: It mixes well with xanthan gum and PAC. Other common polymers also work with it. Under HPHT conditions it acts as a strong thermal stabilizer. Polymers last longer as a result.
Q: How does its breakdown in the environment compare with that of glycol deicers?
A: A4: It breaks down quicker. Less oxygen is needed as well. Aquatic toxicity drops sharply. That makes it a good fit for places where the environment is fragile, for example airports and coastal highways.
Q: Can you give us the technical details we need to make the formula?
A: A5: Yes. We provide exclusive density-concentration comparison charts and professional mixing process guidelines. You can contact us via sxzy@sxzhaoyi.com to obtain complete engineering technical data.
