Full-service OEM manufacturing of calcium carbide CaC2 tailored to client-specific physical and chemical requirements. From specialized particle screening to UN-approved hazardous goods drum packaging, we provide tailored solutions with reliable ocean logistics for regional chemical plants and international distributors.
Our customized calcium carbide cac2 solutions are engineered to meet the precise physical, chemical, and packaging specifications required by global industrial gas operators, chemical manufacturers, and steel mills. Produced in state-of-the-art electric arc furnaces from select high-purity coke and limestone, our product guarantees superior reactivity, low residual sludge, and consistent gas yield (≥295 L/kg).
Recognizing that off-the-shelf commercial grades often lead to operational inefficiencies, we specialize in manufacturing fully tailored calcium carbide cac2 feedstocks. Whether your process requires precise mesh granulometry for continuous dry acetylene generators, low-phosphine chemical grades for PVC synthesis, or specialized private-label drum packaging, our OEM production capabilities deliver reliable, high-performance chemical raw materials tailored to your exact plant parameters.
We offer fully customizable physical and chemical options. Below are our standard export baseline standards alongside customizable options available for bulk procurement:

Tailored Particle Sizing & Granulometry Control:
Equipment variance between wet generators, dry automatic feed systems, and pneumatic injection lances requires strict sizing. We utilize multi-deck mechanical screening to produce customized calcium carbide cac2 particles (0-2mm granules up to 50-80mm heavy lumps) with minimal dust fines (≤3%), preventing hopper bridging and feed lockups.
Custom Chemical Purity & Trace Element Restriction:
For high-purity acetylene gas evolution and chemical synthesis (PVC/VCM), trace contaminants like phosphine (PH3) and sulfur (H2S) cause severe catalyst poisoning. Our smelting engineers adjust raw material dosing to supply refined grades with strictly restricted trace impurities.
OEM Private Labeling & Flexible Packaging Solutions:
We provide complete branding and packaging customization for regional chemical distributors. Choose from 50kg or 100kg heavy-duty steel drums in custom colors, private brand logo printing, multilingual hazardous warning labels, and nitrogen-purged hermetic sealing to prevent moisture ingress.
Customized Acetylene Gas Production: Ideal feedstock for automated wet and dry acetylene generators requiring strict particle sizes and high volumetric gas yields.
Chemical Intermediate Manufacturing: Serves as a fundamental chemical precursor for polyvinyl chloride (PVC) resins, vinyl chloride monomer (VCM), synthetic rubbers, and calcium cyanamide fertilizers.
Metallurgical Hot Metal Pretreatment: Injected as granules (0-2mm or 2-7 mm) into hot metal ladles and torpedo cars for rapid desulfurization and deoxidation in secondary steelmaking.
Handling dangerous water-reactive goods requires strict adherence to international maritime regulations:
Moisture-Proof Packaging: Packed in reinforced, UN-approved 50 kg or 100 kg steel drums sealed under positive nitrogen pressure. Water-proof FIBC bulk bags with aluminum foil inner liners are also available for bulk industrial handling.
International Regulatory Compliance: Full compliance with UN 1402 hazard classification (Class 4.3, Dangerous when wet). Supplied with official Certificate of Analysis (COA) per batch, REACH compliance documentation, and multi-language SDS/MSDS.
Global Shipping Terms: Flexible trade terms including FOB, CFR, and CIF with optimized 20ft container loading schemes (22.5 MT payload per container).
