The definitive technical guide to modern eco-friendly airfield run-way anti-icing operations
Potassium Formate ($CHKO_2$ / $HCOOK$) works by drastically depressing the freezing point of water. It delivers a lower eutectic point of approximately -58°C at a 50% concentration, ensuring exceptional melting activity in the harshest sub-zero weather conditions.
Unlike standard road salts, aviation-grade potassium formate liquid is fully formulated to meet strict AMS 1435D standards. This protects structural components of modern commercial aircraft, including titanium and carbon-disk braking assemblies, from catalytic oxidation.
Traditional chloride-based and urea deicers lead to severe environmental degradation. Potassium Formate offers a very low chemical oxygen demand (COD) and biochemical oxygen demand (BOD), meaning it biodegrades rapidly without starving aquatic habitats of vital oxygen.
Road maintenance crews and airfield operations globally are shifting away from traditional sodium chloride, calcium chloride, and urea. The thermodynamic efficiency of potassium formate is significantly higher. Once applied, the fluid actively weakens the bond between ice and concrete/asphalt pavements, allowing mechanical plows to easily scrape away winter precipitation. Furthermore, it creates a persistent anti-icing barrier that prevents newly falling snow from packing into ice sheets. This residual action decreases application frequency, offering massive operating cost reductions for transport departments and municipal airports.

Shandong Pulisi Chemical Co., Ltd. (Stock Code: 307785) — Direct manufacturer capabilities supplying global markets
Founded in 2006 and listed under stock code 307785 in 2023, Shandong Pulisi Chemical has grown into a major petrochemical, feed, and mining chemical manufacturer. Our production footprint is strategically designed to streamline the chemical supply chain, utilizing key partnerships with Fortune Global 500 companies such as China National Petroleum Corporation (CNPC) and Saint-Gobain.
Our potassium formate production processes are integrated with high-grade synthetic formic acid and potassium hydroxide feedstocks, providing a stable supply line and price protection. We maintain large-scale domestic warehouses to guarantee raw material buffer capacities and safeguard against seasonal spikes in winter deicing demand.
To support global supply chains, we have established mature warehousing and distribution systems at key logistics hubs including Qingdao Port, Tianjin Port, and western border land ports like Alashankou and Khorgos. This network allows for flexible container transport, bulk shipment, and international rail logistics directly to Central Asia, Europe, and the Americas.
Meeting localized municipal mandates, safety regulations, and environmental protocols globally
We provide full compliance with E.U. REACH and South Korea's K-REACH. This ensures smooth customs clearance and regulatory alignment for all European and East Asian supply chains.
Our formate deicers meet localized water conservation standards. They prevent structural corrosion of drainage basins and avoid high nitrogen runoff, which can lead to algal blooms in local streams.
Formulated with advanced corrosion inhibitors, our potassium formate protects steel reinforcing bars in bridge decks, airport ground support equipment (GSE), and sensitive electrical circuits.
Global procurement teams face different logistical requirements depending on destination infrastructure. We support all industry-standard shipping methods, including:
Our core chemical manufacturing portfolio, produced to strict international quality standards
High-performance applications of our chemical range across global industries
Our commitment to quality, capacity, and global service standards
Exporting to more than 100 countries and regions with customs compliance and logistic tracking.
More than 20+ years of export experience, maintaining active partnerships with over 1,000 global companies.
ISO9001:2015, SGS certification, K-REACH registration, and FAMI-QS certification for feed-grade additives.
We leverage our direct chemical raw material integrations to offer competitive pricing options.
Strategic warehousing at key ports ensures fast transportation, reducing transit times during sudden winter events.
An efficient and professional sales team offers support from regulatory paperwork to final port arrival.
Tested and verified by global independent third-party inspection bodies
