- Product Description
Potassium Formate Solid - High-Performance Organic Salt for Industrial Applications for potassium formaic solid
Shanxi Zhaoyi Chemical Co., Ltd. makes formate chemicals. The company was founded in 1988. Today it runs a 27,000 ㎡ production base, and 150,000 tons come off the line every year. Our Potassium Formate Solid (HCOOK) is a white crystalline organic salt. Water dissolves it easily, potassium formaic solid, and it goes into solution fast. Made into brine, it stays clear and reaches a density of 1.57 g/cm³ at most. Industrial grade and pharmaceutical grade are both available. ISO, KOSHER and HALAL certificates cover our products. Oilfield operation, industrial deicing and fine chemical synthesis are the main places they get used. Tough industrial jobs still get the purity and performance they ask for.

High-Density Performance
Fluid density goes up to 13.1 lb/gal with this product. That gives you a solid swap for the weighted drilling muds used before. In deep well drilling, it stops damage to the reservoir formation and keeps oil and gas production layers safe.
Corrosion-Free Chemistry
Our formate salt corrodes metal far less than the chloride products normally used. Metal equipment and infrastructure stay protected for the long run. That means less maintenance work on equipment, and lower running costs overall.
Environmental Compliance
The formula breaks down naturally. BOD and COD values stay low, so the product fits global rules on environmental protection and discharge. Enterprises get strong performance in use, and they still meet green production standards.
Thermal Stability
It maintains stable chemical activity in HPHT environments above 200°C and can effectively stabilize polymer components. It solves the problem of thermal degradation and performance failure of conventional chemical agents under high-temperature working conditions.

How It Works
Potassium Formate Solid does two jobs at once in industrial fluid systems. It works through an ionic reaction mechanism. Once it dissolves in water, potassium ions take the place of sodium ions inside shale structures. Clay then stops soaking up water and swelling. That way the wellbore will not cave in or turn unstable while drilling goes on.
Its high molecular density builds steady hydrostatic pressure, and no suspended solid particles are needed. Wellbore pressure stays under precise control. Downhole operations stay safe, reservoir permeability is fully protected, and oil and gas recovery reaches its highest level.
When it is used for deicing, this product brings the freezing point of water down to -50°C in eutectic mixtures. Ice molecular bonds break apart fast, so snow and ice melt away quickly. Concrete and aluminum alloy infrastructure takes no corrosion damage.
Applications
Oilfield Operations
It works well for making high-performance drilling fluids, completion brines and workover fluids. Inside HPHT reservoirs it keeps wellbore pressure steady. Formation damage is avoided as well, which supports safe and efficient oilfield exploitation.
Snow & Ice Control
Widely used in airport runway deicing and highway anti-icing solutions. It perfectly solves the corrosion problem of traditional chloride deicers to aircraft parts and bridge infrastructure.
Chemical Manufacturing
Used as a high-purity reducing agent and synthetic intermediate for pharmaceutical and fine chemical production of potassium formaic solid, and serves as a stable pH buffer in various special chemical processes.
Leather & Textile Processing
This one acts as a neutralizer and a tanning auxiliary agent. Leather turns out much softer, and textiles hold dye better. Quality of the finished product goes up as a result.
Agricultural Formulations
It delivers potassium that crops can take up from foliar fertilizer blends. Plants stand up better to stress. In harsh conditions, the crop also grows with better quality.

Certifications & Compliance
Our production base strictly complies with ISO 9001:2015 quality management system standards. The product holds valid KOSHER and HALAL certifications, meeting the requirements of food-grade auxiliary applications.
All products conform to EU REACH environmental regulations. We can provide complete SDS safety documents. Each batch is inspected by third-party institutions to ensure all technical indicators meet export standards and customer requirements.

Packaging Options for potassium formaic solid
Standard Packaging
The product goes into 25kg multi-layer bags that keep moisture out. Each bag carries a PE inner liner. Every pallet holds 1000kg and is stacked evenly, which makes container loading and long-distance shipping easier.
Bulk Solutions
500kg large jumbo bags are available for large-scale industrial bulk procurement. We support customized packaging solutions according to customer's on-site handling and storage needs.
Quality Protection
Every package is sealed airtight. Desiccants sit inside each one, so outside moisture stays out. That keeps the product from soaking up water and turning into lumps while it is shipped or stored.

Manufacturing Process
Our production uses a proven neutralization method. Formic acid and potassium hydroxide act as the raw materials, and both come in high purity. Reactors hold a steady temperature, so the reaction goes far enough. Raw materials turn over almost completely, and very few by-products appear.
Crystallization happens in several precise stages. Particle size in the finished product stays evenly spread because of this. Dissolution rate holds steady, and every batch performs the same way in the field.
Automatic washing units and low-temperature dryers pull out leftover impurities. The finished product then goes through screening and fine processing. That way it meets the custom technical specs each industry asks for.

FAQ
Q: What are the core advantages over sodium formate?
A: A1: Potassium formate has stronger shale inhibition performance for oilfield drilling, and can prepare higher-density brine, delivering more stable downhole pressure control effect.
Q: Is this product available for food-grade usage?
A: A2: Yes. Our KOSHER and HALAL certified grades fully meet food additive standards. You can specify food-grade requirements when placing orders.
Q: How to store the hygroscopic solid properly?
A: A3: Seal the package tight again once you are done. Store it in a dry warehouse. Humidity in there should stay below 60%. That way the powder will not soak up damp and cake up.
Q: How long does the product stay good for?
A: A4: Keep it sealed and dry, the usual way. Our product then lasts up to 24 months. Performance stays stable for that whole period.
Q: Can you provide complete technical documents?
A: A5: Sure. We provide complete TDS, MSDS and COA documents for every shipment. You can contact us via sxzy@sxzhaoyi.com for additional technical support.
