Explore the physical and chemical standards defining our premium technical grade calcium formate, engineered for concrete acceleration and industrial synthesis.
Calcium Formate ($Ca(HCOO)_2$, CAS No. 544-17-2) is a free-flowing crystalline powder valued for its role as a setting accelerator in drymix mortars, self-leveling compounds, tile adhesives, and concrete. In industrial applications, the 98% Technical Grade specification ensures high calcium content ($Ca \ge 30.1\%$) and minimal impurities (such as heavy metals, insolubles, and excessive moisture). These properties are critical for preventing efflorescence in drymix mortar formulations and avoiding interference with complex organic additive chemistry.
| Parameter / Specification | Technical Grade Standard (98% Min) | Test Methods / Standards |
|---|---|---|
| Appearance | White crystalline powder or granular form | Visual Inspection |
| Assay ($Ca(HCOO)_2$) | ≥ 98.0% | Titration Method |
| Calcium Content (Ca) | ≥ 30.1% | ICP-OES / Complexometric Titration |
| Moisture (Loss on Drying) | ≤ 0.5% | Drying Method at 105°C |
| Water Insolubles | ≤ 0.3% | Gravimetric Method |
| pH (10% aqueous solution) | 6.0 - 7.5 | pH Meter |
| Heavy Metals (as Pb) | ≤ 0.002% (20 ppm) | Atomic Absorption Spectroscopy |
Understanding how synthetic routes influence the final product quality, stability, and compatibility in construction formulations.
This pathway involves reacting high-purity formic acid ($HCOOH$) directly with calcium hydroxide ($Ca(OH)_2$) or calcium carbonate ($CaCO_3$). This method yields a product with minimal byproduct salt impurities, making it the preferred route for technical grades requiring very low sodium content to prevent efflorescence in architectural mortars.
Calcium formate is generated as a byproduct during the synthesis of pentaerythritol under alkaline conditions. Advanced crystallization and filtration technologies are utilized to extract technical-grade calcium formate from this process. This route offers cost-competitive scaling for mass-market construction applications.
By controlling crystallization parameters, Pulisi ensures our 98% Tech Grade contains very low residual sodium and sulfates. This helps prevent efflorescence in finish mortars and white cements, ensuring architectural finishes maintain their color and aesthetic quality over time.
High-purity calcium formate acts as a functional additive across multiple heavy industries and regional settings.

1. Accelerating Concrete Hydration under Sub-Zero Temperatures: In cold-weather regions (such as Northern Europe, Northern China, and Canada), standard concrete setting slows significantly, which can impact project timelines and mechanical integrity. Calcium Formate accelerates cement hydration by facilitating the dissolution of tricalcium silicate ($C_3S$) and promoting early-strength ettringite formation. Unlike traditional calcium chloride accelerators, it does not induce corrosion in structural steel reinforcement.
2. Chrome Leather Tanning Optimization: In chrome tanning processes, calcium formate acts as a masking agent. It modifies the coordination state of chrome complexes, allowing chromium ions to penetrate the collagen fiber matrix of the hide before cross-linking occurs. This leads to a more uniform distribution of chrome, improved leather yield, and lower levels of chromium in tanning effluents.
3. Oil Well Cementing and Drilling Mud Stabilization: High temperatures and pressures in deep wells require cementing materials with reliable hydration kinetics and thermal stability. In shale gas extraction, calcium formate serves as a shale stabilizer, preventing clay swelling and maintaining bore hole integrity in water-sensitive formations.
A closer look at our integrated raw material supply, chemical parks, and port warehousing operations.
Shandong Province is a major hub for China's petrochemical and basic chemical industries. Pulisi Chemical's manufacturing facility is located in Zibo, offering direct access to key industrial raw materials like synthetic ammonia, carbon monoxide, and formic acid. This localized supply chain reduces upstream raw material transport costs and minimizes manufacturing disruptions.
Our logistics framework includes strategically placed warehouses near major shipping hubs. By maintaining inventory in Qingdao Port, Tianjin Port, and Xinjiang border gateways (Alashankou & Khorgos), we can offer flexible shipping arrangements. This logistics network helps mitigate delays caused by international shipping bottlenecks, supporting consistent delivery schedules for our clients.
Our commitment to quality, environmental responsibility, and international standards.
To support global distribution, we maintain compliance with regional chemical frameworks including EU REACH and Korea REACH (K-REACH). Our products undergo routine analytical testing for heavy metals and purity, verified by SGS and German BV. This quality control framework ensures that our technical and feed-grade products consistently meet safety and environmental standards.
