High Purity Solid Potassium Formate | Premium Grade Chemical Solution for Advanced Industrial Applications
SHANXI ZHAOYI CHEMICAL CO., LTD has been in business since 1988. We make specialty formate chemicals, and buyers trust us for it. Our production plant covers 27,000 ㎡ and puts out 150,000 tons a year. Industrial chemical materials from our plant ship to customers worldwide. One item we supply is High Purity Solid Potassium Formate (CAS 590-29-4). Impurity levels sit under 0.2%, and moisture stays within 1.0%. This white crystalline powder is homogeneous. Its chemical composition holds steady, so it fits low-contamination precision work. Our high-purity grade carries ISO, KOSHER, and HALAL certification. Industrial processing plants use it. So do electronic chemical makers and lab research teams around the world.

Key Features & Benefits
This product is made to give quality that stays stable and repeatable. Your whole production process runs better with it.
At high operating temperatures, the formulation stays fully intact. Thermal stability reaches up to 210°C. Strict impurity control blocks unwanted chemical reactions, and those reactions cause trouble during catalyst preparation and electronic chemical manufacture. Block them, and the final product comes out stable and dependable.
Buy in bulk and the quality stays the same from one batch to the next. Our chemistry holds steady, so your line throws away less and gets more product out of every run. The grade is eco-friendly too, and it breaks down naturally. It follows the international sustainability rules the industry works by. So you get strong performance plus cleaner production.

How It Works
Put this product in water and it breaks apart all the way. Only pure potassium cations and formate anions are left. No extra impurities remain, so those ions will not drag contaminants into your reaction or formulation systems.
Making catalysts and doing precision chemical synthesis both need exact, controlled reactions. Pure potassium ions help you get there. Trace impurities stay extremely low as well. So precision electronic components see no interference with signal or performance, and the electronics industry can rely on them.
Temperature-sensitive materials get protection from formate anions. They stop oxidation and heat damage. This happens through steady pH buffering and antioxidant action. That keeps manufacturing outputs consistent. Chemical performance stays constant too, even when operating conditions are tough and complicated.
Applications
Laboratory Research & Development: This is a good fit for making analytical reagents and standard solutions in chemical labs. It cuts out test result variance that trace contaminants bring.
Fine chemicals and pharmaceutical intermediates at the high end come out of precision chemical synthesis. Purity stays high and never shifts, which keeps reaction routes and product quality consistent.
Catalyst Manufacturing: Low impurity levels are normal here. That makes it a strong raw material for high-performance catalysts. A lot of specialty chemical and petrochemical output depends on those catalysts.
Electronic Chemicals: The purity limits set for this grade are tight, and it passes them. Semiconductors use it, and circuit boards do too. Electronic work done to fine tolerances calls for specs that narrow. It hits them.
High-Performance Fluid Formulations: Specialty industrial fluids use them, and so do drilling fluids. In the field, results stay the same run after run. Density does not drift either.

Certifications & Compliance
Throughout production, we uphold a rigorous ISO-certified quality management system. Our goods are able to service a variety of international industrial markets because all manufacturing procedures adhere to KOSHER and HALAL requirements.
Each production batch is subjected to comprehensive expert testing and quality inspection. To meet clients' needs for quality assurance and project audits, we offer comprehensive compliance certificates and technical documentation. To maintain consistent high-purity standards, our QA team keeps an eye on all important production links.

Packaging Options
We make flexible packaging that fits the job. It keeps products stable while they sit in storage or move in transit. Our standard 25kg moisture-proof bags containing High Purity Solid Potassium Formate block moisture. That stops spoilage.
Dust-free fiber drum packaging is one of the options we offer. It fits high-purity, sensitive jobs where contamination cannot happen. Customers in pharmaceutical and electronic manufacturing get clean packaging built to their own production standards.
Each package carries a batch number on its label. The production date and the technical specs are printed there too. That way your quality management system can trace every product right back to its batch.

Manufacturing Process
We have decades of professional experience in formate chemical production. Our base is high-grade raw materials with low impurity levels. Tight control over reaction parameters helps crystals form the right way. That raises product purity.
Trace impurities are removed step by step with multi-stage deep purification technology. That is what gets us to high-precision industrial standards. The full production process uses automatic monitoring, which keeps all technical indicators steady.
Drying runs at low temperature, so moisture stays under 1.0%. The crystal structure holds up. Performance stays intact as well. Every batch is tested before we pack it and send it out. Quality then holds steady, order after order.

Q: How should I store it?
A: A2: Leave the product in its sealed packaging. Pick a spot that's clean and dry. Air flow matters. Do not let moisture get near it. Keep acids and strong oxidants away. That keeps performance steady over the long term.
Q: Is this product okay to use in food-grade processing?
A: A3: This is a high-purity industrial-grade product for precision industrial use only. It has no food-grade certification and is not applicable for food and beverage production.
Q: What is the valid shelf life?
A: A4: Keep it sealed and dry as usual, and the product still meets the technical specifications for 24 months.
