- Product Description
Potassium Formate Granules - High-Performance Industrial Grade Solution for Drilling & Deicing Applications
Shanxi Zhaoyi Chemical Co., Ltd. is a professional manufacturer specializing in formate and acetate chemical series. Founded in 1988, we own a 27,000 ㎡ standardized production base with a stable annual output of 150,000 tons. We supply Potassium Formate Granules (CAS 590-29-4), featuring white free-flowing particle texture, low dust generation and ultra-fast water solubility. With valid ISO, KOSHER and HALAL certifications, our industrial-grade granules have been widely exported to Europe, America, Asia and other global markets, delivering stable and reliable material solutions for oilfield drilling, road deicing and diversified industrial production scenarios.

Key Features & Benefits
Different from traditional crystalline potassium formate, our this product are optimized with exclusive granulation technology to solve common on-site handling pain points. In addition to increasing workshop operation safety and preventing raw material waste from dust scattering, the free-flowing particle design successfully lowers dust volatilization during feeding and transportation.
The granular structure considerably expands the area in contact with water, resulting in a much quicker rate of disintegration. It improves overall operational efficiency by reducing on-site batching and mixing time by up to 40% as compared to conventional products.
The granules keep their free flow even when storage and transit conditions turn humid. Expert moisture-proof packing is what makes that possible, and caking never becomes a problem. We build these products from a high-purity raw material formulation. Its molecular weight sits at 84.12 g/mol. Quality stays stable from batch to batch. In use, our solutions act the same way every time, whether the job is industrial deicing or high-standard drilling fluid preparation.

How It Works
This product outperform ordinary powder products in handling performance and application effect. The grain shape is uniform. Free flow during transportation and feeding comes from that. A larger specific surface area helps too. Once the granules hit the water, ions disperse quickly and form a uniform, stable aqueous solution.
In oilfield drilling applications, dissociated potassium ions steady active clay formations and hold back shale swelling. The formate component buffers heat well at high temperatures. That is what protects polymer systems downhole, even above 200°C.
For deicing and snow melting jobs, this product lowers the freezing point of water. Its lowest working temperature reaches -50°C. Ice melts the moment the granules touch it. Roads and runways get an even spread. Bridge surfaces are no different. Deicing ends up fast and uniform.
Applications
Oilfield Operations: This product is used to make high-density drilling brine. The top density it reaches is 1.57 g/cm³, which fits HPHT deep wells. No solids go into the mix. That keeps the reservoir formation from being damaged, and shale inhibition stays strong for long-distance drilling work.
Deicing & Snow Melting: Airport runways, highways and bridge decks all get deicing treatment with it. Older chloride deicers work differently. Corrosion stays ultra-low here. Aircraft equipment and steel-reinforced infrastructure will not be damaged.
Industrial Batching: Ideal for chemical manufacturing processes requiring rapid dissolution and high purity. The dust-free granular form perfectly adapts to automated batching and conveying systems, optimizing factory production efficiency.
Leather Processing: Applied in leather tanning formulations. Its stable controlled release performance and dust-free characteristics greatly improve workshop operating environment and finished product consistency.

Packaging Options
To accommodate varying order amounts and storage requirements, we provide a variety of packing options. With tear-resistant and moisture-proof features to guaranty product safety, standard 25 kilogram moisture-proof bags are appropriate for small-batch experiments and traditional industrial use.
We provide 500 kg and 1000 kg bulk jumbo bags with a high-barrier inner liner and a UV-resistant outer layer for large-scale industrial purchases. The product can continue to operate steadily for up to a year with conventional warehouse storage.
Manufacturing Process
For production, we choose pharmaceutical-grade, high-purity raw materials. To guaranty full raw material conversion and good product purity, the synthesis reaction is conducted in constant-temperature precision reactors with real-time pH monitoring.
After synthesis, the solution goes through precision filtering in several stages. That step holds the impurity level under 0.5%. Granulation then runs on professional equipment. It keeps particle size even, and it also makes the product flow better and give off less dust.
A low-humidity drying step at constant temperature keeps moisture out and stops the product from caking. Checks sit at many points across the whole process, before packaging and delivery. Purity gets tested there. So does particle size, and so does dissolving performance.
Why Choose Us
With more than 35 years of formate chemical manufacturing experience, we have mature and stable production technology. The 150,000-ton annual output capacity effectively guarantees continuous and sufficient supply even in peak demand seasons.
Our sales and logistics network now spans the globe. It covers Europe, America, Asia, and other regions. B-end buyers worldwide get fast delivery. They also get technical support from local teams.
Customers come first in how we work. From tuning a formula to hands-on technical support, we cover the whole job, plus help with problems after the sale. What we want is a partnership that lasts for years, not a single order.
FAQ

Q: What keeps granules from caking up while they sit in storage?
A: A1: Keep the product in its original sealed bag. Store it in a dry warehouse with good airflow. Keep it out of direct sunlight and away from damp spots. Once you open the bag, close it again right away. That stops moisture from getting in and forming lumps.
Q: How quickly do the granules dissolve?
A: A2: Leave them at normal temperature with moderate stirring, and the granules dissolve all the way in 3-5 minutes. Cold water slows this down a little: the time goes up to 8-10 minutes.
Q: Can it be used with automated feeding systems?
A: A3: Yes. The granules are the same size throughout, and they flow freely. No bridging, no clogging. They fit any automatic conveying or batching unit.
Q: Is this product safe to use around food or drinking water?
A: A4: These granules are industrial grade. They are meant for drilling, deicing and industrial batching. Need food grade material, or something that comes into contact with drinking water? Talk to our team. They can send you special grades and the matching certification documents.
Q: What is the standard shelf life?
A: A5: Under normal conditions, keep the product dry and the seal unbroken. An unopened unit lasts up to 24 months. Its performance stays stable.
