- Product Description
Solid Sodium Formate Powder - Industrial Grade Chemical Solution for Multi-Industry Applications
Since 1988, Shanxi Zhaoyi Chemical Co., Ltd. has made solid sodium formate powder (CAS 141-53-7). It's dependable. We have a 27,000 m² manufacturing base. Every year, we can produce 150,000 tons. Our facility makes three grades. One is 92%. Another is 95%. The third is 98%. This white crystalline powder stays thermally stable up to 253°C, its melting point. Water solubility is high: 97g/100ml at 20°C. We hold ISO, KOSHER, and HALAL certifications. They guarantee constant quality for international markets. Our product works in oilfield drilling. Leather processing uses it too. Environmental protection gets a boost as well.

Key Features & Benefits
High Purity Performance
Our this product hits 98% purity. Demanding industrial processes? It handles them. The mix is precise. Your formulations will react the same way every time.
Reducing Capability
The formate ion structure delivers strong reducing power for precious metal recovery operations. Your metal precipitation processes become more efficient with lower chemical consumption.
Environmental Compatibility
This biodegradable organic salt has a lower Chemical Oxygen Demand (COD) than acetate substitutes. You keep operating effectively. Strict discharge standards are still met.
Thermal Stability Advantage
Temperatures over 250°C will not break this substance down. It stays stable. Processing cycles leave its chemical behavior unchanged, and that helps when your application runs hot.
Non-Corrosive Chemistry
Salts made with chloride behave in another way. This compound keeps your equipment clear of electrochemical corrosion. Where metal is sensitive, that stretches how long your infrastructure lasts.

How It Works
Chemical Reduction Mechanism
The formate ion (HCOO⁻) gives up electrons during oxidation-reduction reactions. Metal ions get reduced thanks to that transfer. You see it at work in precipitation processes. It also matters for chrome fixing in leather.
Freezing Point Depression
Sodium formate dissolves in water, and ice crystals cannot form. The point where water freezes drops. For infrastructure work, deicing keeps working at temperatures as low as -18°C.
pH Buffering Action
When conditions are acidic, the compound keeps alkaline levels steady. Tanning and textile processes gain from this. pH stays in check. Dye uptake goes up, and chemical reactions run better.
Complexation Properties
Formate ions bind with metal cations in drilling fluids. The result is a stable complex. This keeps shale from hydrating and stops formation damage during oilfield operations.
Applications
Oilfield Drilling Operations
You can control wellbore pressure with brines that have no solids. They go up to 1.3 g/cm³. This material stops clay swelling in sensitive shale formations.
Leather Tanning Industry
With your chrome tanning, penetration and fixation rates come out higher. Leather gets more softness and even color from the reducing environment this creates.
Concrete Acceleration
Curing times get faster. Winter construction projects gain from that. Cold weather does not stop you from keeping pouring schedules. Structural integrity stays intact too.
Textile Printing & Dyeing
In vat dyeing, this compound acts as a reducing agent. Your fabric takes in more color when you use it. After washing, the shade holds up better too.
Snow & Ice Management
Deicing fluids for airport runways and bridge decks have to work with solid Sodium Formate Powder without corroding metal. On aluminum aircraft parts and steel reinforcement, they block chloride damage.

Certifications & Compliance
Our plant runs ISO quality management systems, so every batch comes out the same. KOSHER and HALAL certificates back up our production standards for food-grade use. Every product meets REACH rules for Europe, along with Chinese GB standards for chemical safety.

Packaging Options
Standard Moisture-Resistant Bags
Every bag weighs 25 kg. Kraft paper forms the outer layer. A polyethylene liner sits inside. While the product waits in storage, that liner keeps moisture out. Here a few layers do the job together. They keep the product safe as it moves through distribution chains.
Bulk Packaging Solutions
Jumbo bags come in custom sizes, from 500 kg up to 1000 kg. Big industrial buyers get the volumes they need. With the right configuration, you throw away less packaging. Handling costs drop too.
Container Loading
20-foot containers hold up to 25 metric tons with proper palletization. Our logistics team ensures optimal loading patterns for your shipping requirements.

Manufacturing Process
Raw Material Synthesis
Carbon monoxide goes through a reaction with sodium hydroxide. That step is how we control the purity we end up with. Batch after batch, the chemical composition comes out the same.
Crystallization Control
Keep the crystallization at a controlled temperature and the particles all come out the same size. The powder pours without clumping. It dissolves easily too.
Quality Screening
Filtration runs through a few stages. Impurities get pulled out at that point, before the last drying. Nothing moves to the warehouse until the lab tests are done.
Moisture Management
Inside controlled drying chambers, moisture falls below 1.0%. Packaging is where the hygroscopic properties get handled. That is what holds the product stable.

FAQ
Q: What sets 92% purity apart from the 98% grade? A: In the higher purity grades, fewer sodium carbonate and sodium chloride contaminants remain. Impurities affect performance in drilling fluids and critical applications, so we recommend the 98% grade.
Q: What is the best way to keep this material in storage over the long term? A: Put it in sealed containers. The warehouse should stay below 25°C, and relative humidity must not go above 60%. Stored that way, product quality holds steady for 24 months.
Q: Does it work as a replacement for chloride salts on every deicing task? A: On most infrastructure jobs it performs well. It keeps working down to -18°C. When arctic cold drops below -25°C, blended formulations may be needed.
Q: Is it suitable for food-grade work? A: Yes. Our KOSHER and HALAL certified grades meet food additive regulations. Contact us to ask for certificates of analysis and regulatory documentation.
Q: How small an order can you take? A: A single pallet is fine. That is 1 ton. We can also ship a full container load. The more you buy, the better the price. Our sales team has the numbers.
