- Product Description
potassium formate liquid | High-Performance Industrial Grade for Drilling & De-icing
For more than 35 years Shanxi Zhaoyi Chemical Co., Ltd. has been making chemicals. The company was set up in 1988. Output from our 27,000 ㎡ factory sits at a steady 150,000 tons every year. Potassium formate liquid is what we mainly supply. This clear industrial liquid is made for hard jobs. Oilfield drilling is one of them. Melting snow and ice is another. A third is fine chemical processing. Purity stays at 74-75%. Density comes to 1.57 g/cm³ at 20°C. Very low temperatures do not stop it. Even at -50°C the performance holds steady. ISO, KOSHER, and HALAL international certifications are held by our production system. Zero-solid precision filtration is what we use. Corrosion levels stay very low as a result. Key problems for industrial clients worldwide get solved. Stable drilling under high pressure is one. Anti-corrosion protection for infrastructure is the other.

Key Features & Benefits
This product gets around many hidden operational risks that come with traditional brine products. Its formula has no solids at all. That completely stops barite from sagging during long-term well completion jobs. Formation permeability in reservoir drilling stays above 90%. Drilling progress stays steady and efficient.
Shale inhibition comes with it, and chloride emission rules never get in the way. The crystallization point sits very low. So the product ships to cold regions all year round. Storage there is no problem. Neither is daily use. Calcium-based liquids are a different story. Steel equipment and concrete infrastructure stay free from corrosion with our solution. Strict industrial BOD/COD discharge standards are met too, which supports environmental protection.
Density can reach 1.60 g/cm³. That gives reliable pressure control for HPHT (high temperature and high pressure) well drilling operations. The product works in two ways. Agricultural planting uses it as a chloride-free nutritional substrate with high efficiency. It also acts as a special de-icing agent for airport runways and municipal infrastructure. That use is safe and compliant. Multi-scenario industrial value is what comes out of it.

How It Works
This product delivers results that hold steady and work well. Two main things make this happen. The ions interact with each other, and the freezing point goes down. In drilling fluids at oilfields, free potassium ions slip fast into the pore structures of shale. Water then cannot get soaked up by the clay, so the clay does not swell. The well stays in one piece, and other risks on the job are kept away too. Liquid density holds steady thanks to the formate anion. Nothing solid ends up floating in the mix. Permeability in the reservoir is not harmed.
Roads, bridges, and other infrastructure all get de-iced with this product. It works on ice crystals at the molecular level. Water molecules would rather bond with potassium ions and formate ions. That tears the firm lattice apart, the one that holds solid ice and snow in place. Even at very low temperatures the de-icing action still holds up. Traditional sodium chloride agents fail completely right there. Harsh winter conditions are no problem for this product.
Out on the farm, formate anions break down on their own into carbon dioxide and water. Nothing polluting is left over. The nutrients that come out of this feed the microorganisms living in the soil. Potassium ions go straight into the crop roots. That supplies the potassium the plants need, so the quality of crop growth goes up.
Applications
Oilfield Drilling & Completion: It works as a base brine that gives strong performance. Crews reach for it in open-hole completion and in deep-well packer fluid. Through reactive shale offshore, the wellbore stays stable with it. Rules that ban chloride emissions are tight, and this fluid follows them.
Infrastructure De-icing: Runways get a layer of it at airports, so snow melts and ice clears. Highway bridges rely on it too. Industrial operation platforms do the same. Corrosion stays low. Aluminum parts on aircraft and reinforced concrete facilities come through winter maintenance without corrosion damage.
Agriculture: No chloride is present, so it serves as a potassium fertilizer and fits drip irrigation systems nicely. Emitters in the lines will not clog up. High-value cash crops get potassium fast, tobacco and berries among them, and that pushes yield and quality higher.

Chemical Processing: Here it works as a catalyst and a pH buffer. You will find it in leather tanning, in fixation for printing and dyeing, in speeding up cement setting, and in other factory processes. The pH of the reaction holds steady. Output climbs. So does the quality of the finished goods.

Certifications & Compliance
Our production base has passed ISO 9001:2015 quality management system certification, realizing full-process standardized quality control to ensure consistent and stable performance of each batch of products. The food-grade production line holds valid KOSHER and HALAL certifications, meeting the production standards of pharmaceutical intermediate raw materials.
Every product meets EU REACH registration rules, so it can be sold in European markets without trouble. Agricultural-grade products stick to AAPFCO heavy metal limit standards. For each shipment, we supply full MSDS safety data sheets and third-party official COA test reports. These help customers clear customs and pass quality checks.

Packaging Options
1000L IBC Tanks: Made for large-scale oilfield industrial operations. Loading and unloading of potassium formate liquid are easy thanks to the forklift-compatible structure. UN-certified, the container keeps product from getting contaminated during long-distance cross-border transport.
200L Plastic Drums: These suit farm supply dealers and fine chemical plants. High-density polyethylene is what they are made of, so they stack well. Every drum carries an anti-counterfeiting seal and a leak-proof seal. Product stays safe in the warehouse or out on the road.
Flexibags: A cheap way to pack 20-24MT into a container load. Inside each bag sits a throw-away food-grade PE inner liner. Cross-contamination is no longer a worry. For bulk shipments overseas, this setup works well.

Manufacturing Process
Continuous reactor neutralization is what our production line runs on. High-purity food-grade formic acid and potassium hydroxide are the main raw materials. Temperature holds steady all through the reaction. Filtration takes place in several exact stages. That keeps insoluble impurities below 0.05%. So the liquid product won't clog precision irrigation or drilling equipment.
We run real-time HPLC online monitoring at every stage of production. It keeps product purity inside the standard 74-75% range. A heavy metal ion exchange system also pulls lead, cadmium and other harmful heavy metals down to below 5ppm. Purity then meets pharmaceutical-grade standards.
All finished products will undergo strict density verification and microbial testing before warehousing, with multi-dimensional quality inspection to ensure all indicators meet industrial application standards and deliver qualified products to customers.

FAQ
Q: What is your minimum order quantity?
A: A1: We support flexible trial orders, with the minimum order of 1 set of 1000L IBC tank. Container-load bulk orders can enjoy exclusive bulk discount prices.
Q: Is this industrial grade product safe to use when treating drinking water?
A: A2: Drinking water systems are not a fit for this standard industrial this product. It will not work there. Send us your specs instead. Food-grade products can be supplied made to order, and those meet NSF/ANSI 60.
Q: When it ships in winter at very low temperatures, what stops the product from crystallizing?
A: A3: The freeze point here is very low, at -50°C. On its own, it stays fluid. For shipping in extreme cold, insulated containers are what we suggest. Another way is to keep it warm in storage after it arrives.
Q: Can we get expert technical help from you when we formulate drilling fluids?
A: A4: Yes. Our chemical engineers are professionals and they handle everything. This includes designing drilling mud systems, optimizing formulas, and guiding operations on site.
Q: How long do unopened products last?
A: A5: Leave the product unopened. Store it somewhere dry, in a warehouse that gets airflow. Shade it. Direct sunlight is off limits. Performance holds steady that way. Every specification still holds for up to 24 months.
