Shandong Pulisi Chemical Co., Ltd. was established in 2006 and has rapidly grown into a prominent market leader in chemical synthesis, supply, and global trade (Stock Code: 307785). Our strategic focus centers around critical industry sectors including petrochemicals, mining chemicals, feed chemicals, and pharmaceutical intermediates. Over nearly two decades of operation, we have solidified long-term, mutually beneficial partnerships with numerous Fortune Global 500 giants such as China National Petroleum Corporation (CNPC) and Saint-Gobain.
Our operational framework is systematically tailored to put customer requirements first. We provide precision-engineered chemical solutions that elevate end-product quality and bolster our client's competitive advantages in tight markets. With advanced logistics hubs strategically located at key shipping corridors including Qingdao Port, Tianjin Port, and major Western inland gateways (Alashankou, Khorgos), we deliver reliable containerized cargo solutions around the world.
Sulfamic Acid (also known as amidosulfonic acid, $H_3NSO_3$) is a highly stable, white crystalline, mono-protic solid acid. In a vast range of industrial domains, Sulfamic Acid is preferred over volatile and highly corrosive liquid mineral acids due to its ease of handling, transport, and exceptional dissolution kinetics.
Ultra-high purity is the key differentiator for critical industrial applications. Any minor impurities, such as heavy metal ions or excess sulfuric acid, can severely alter reaction outcomes, cause unintended corrosion on titanium or stainless-steel surfaces, or lead to product caking in dry mixes. Our 99.8% Grade minimizes chloride and sulfate impurities to negligible parts-per-million levels.
Unlike hydrochloric or nitric acids, dry sulfamic acid does not volatilize or release dangerous fumes under ambient conditions. This significantly lowers ventilation costs in industrial plants, reduces handling hazards for factory operators, and reduces overall transportation costs, as solid acid is considerably safer to ship globally.
Modern environmental regulatory frameworks favor the use of organic-acid alternatives that display lower toxicity levels in wastewater. Sulfamic acid biodegrades rapidly in municipal systems into harmless ammonium sulfate, minimizing chemical oxygen demand (COD) in wastewater treatment lines.
From specialized cleaning chemicals to industrial scale-removal operations, Sulfamic Acid 99.8% serves as a vital component in modern production.
In cooling tower maintenance, industrial boilers, and marine condensers, calcium carbonate and iron scale deposits build up, reducing heat transfer efficiency. Sulfamic Acid 99.8% forms highly water-soluble calcium sulfamate salts, allowing rapid descaling without attacking the underlying base metals (copper, iron, steel) when properly inhibited.
In organic synthesis, excess nitrous acid ($HNO_2$) must be removed during diazotization reactions to prevent side product formation. Sulfamic Acid is the industrial standard reagent for this, reacting rapidly and cleanly to yield nitrogen gas ($N_2$) and sulfuric acid ($H_2SO_4$), which leaves no organic residues.
In pulp and paper mills, sulfamic acid acts as a stabilizer during the chlorination and chlorine dioxide bleaching steps. By reacting with hypochlorous acid, it minimizes degradation of pulp cellulose fibers, resulting in higher tensile strength and brightness values in high-grade papers.
Commercial tile cleaners rely heavily on sulfamic acid due to its mild reaction with grout lines compared to phosphoric or hydrochloric acid. It quickly dissolves hard-water scaling, efflorescence, and rust stains, leaving ceramic surfaces clean and bright without damage.
The high solubility of metal sulfamates makes sulfamic acid an ideal additive in specialty electroplating baths. It is heavily utilized in nickel sulfamate plating processes, producing low-stress coatings on precision electronic components and aerospace hardware.
Shandong Pulisi provides bespoke chemical formulations containing customized surfactants, corrosion inhibitors, and color indicators to match your specific descaling, cleaning, and chemical synthesis requirements globally.
Our commitment to R&D is driven by green chemistry principles. The traditional synthesis of Sulfamic Acid involves the reaction of urea with fuming sulfuric acid (oleum):
$CO(NH_2)_2 + H_2S_2O_7 \rightarrow 2 H_3NSO_3 + CO_2 \uparrow$
To scale up this reaction efficiently and safely, our Zibo plant implements an advanced continuous sulfonation process. By using digital flow sensors and real-time automated cooling systems, we maintain precise temperature parameters, preventing over-reaction and reducing raw material waste.
Looking to the future, Shandong Pulisi is investing in recrystallization technology to further reduce trace moisture and achieve a consistent crystal size distribution. This prevents the clumping and caking that typically occurs during oceanic shipment across diverse temperature zones, ensuring the chemical remains free-flowing upon delivery.
Shandong Pulisi leverages its geographic location and advanced logistics network to ensure seamless deliveries regardless of changing global market dynamics.
Our main chemical production plant is located in Zibo, Shandong. Zibo is a major chemical industry center in China, providing us with direct, local access to raw chemical components, specialized engineers, and immediate feedstock deliveries.
We maintain extensive warehouse space at key commercial ports including Qingdao Port and Tianjin Port. This allows us to pre-stage high-demand products like Sulfamic Acid 99.8% for immediate vessel loading, reducing ocean transit lead times.
For overland cargo transit to Central Asia and Europe, we utilize key dry ports like Alashankou and Khorgos. By using combined rail-and-sea routing, we offer flexible supply strategies to help you avoid bottlenecks at busy ports.
