Essential Chemical Intermediary: High reactivity makes it the ideal primary feedstock to generate high-yield acetylene for PVC monomer (VCM) synthesis and organic organic chemical derivatives.
Controlled Impurity Levels: Strictly managed phosphine (PH3≤0.08%) and hydrogen sulfide (H2S≤0.10%) content, minimizing catalyst poisoning and extending reaction column lifespans in chemical reactors.
Reliable Bulk Supply: Flexible options to buy calcium carbide in full container loads (FCL) with continuous factory output to support non-stop chemical manufacturing operations.
High Gas Yield Consistency: Guarantees an acetylene gas yield of ≥295L/kg- 305L/kg, ensuring predictable stoichiometric conversion ratios.
Hermetic Safety Packaging: Packed in heavy-duty 50kg/100kg steel drums with nitrogen (N2) purging to eliminate atmospheric moisture exposure during transoceanic shipping.
Calcium Carbide (CaC2) serves as a foundational inorganic chemical raw material essential for modern heavy organic synthesis and polymer manufacturing. As a major global manufacturer and chemical supply partner, we provide high-purity industrial-grade Calcium Carbide designed specifically to meet the high-volume requirements of Polyvinyl Chloride (PVC) resin production, calcium cyanamide formulation, and fine chemical processing.
If your chemical manufacturing operations require a dependable, uninterrupted supply chain, choosing to buy calcium carbide from our factory direct facilities ensures consistent reaction kinetics, optimal stoichiometric yield, and reduced production downtime.

In the calcium carbide-based PVC manufacturing process, acetylene gas generated from CaC2 hydrolysis reacts with hydrogen chloride (HCl) to form Vinyl Chloride Monomer (VCM). Our high gas yield ( ≥295 L/kg) maximizes acetylene release per metric ton of raw material, lowering energy consumption and optimizing raw material efficiency in large-scale PVC plants.
Beyond PVC resins, chemical plants that buy calcium carbide utilize it as a versatile carbon-carbon backbone source. It acts as a primary precursor for:
Synthetic Rubber: Chloroprene rubber and butadiene synthesis.
Agrochemicals & Fertilizers: Calcium cyanamide (lime nitrogen) production.
Specialty Chemicals: Reagents for pharmaceuticals, solvents (1,4-butanediol / BDO), and organic synthesis intermediates.
Minimized Catalyst Poisoning: By maintaining strict thresholds on impurities like phosphine (PH3) and hydrogen sulfide (H2S), our product minimizes contamination in chemical reactors, prolonging the lifespan of expensive mercury or precious-metal catalysts used in downstream synthesis.
Uniform Reaction Rate: Controlled screening and low dust ratio ensure steady hydrolysis inside continuous acetylene generators, maintaining constant gas pressure for synthetic operations.
Cost-Effective Bulk Procurement: B2B buyers looking to buy calcium carbide benefit from direct factory wholesale pricing, flexible payment terms (T/T, L/C at sight), and reliable long-term contract fulfillment.
Due to its reactivity with moisture (generating flammable acetylene gas), international transport of Calcium Carbide demands strict compliance with dangerous goods regulations (IMDG Code Class 4.3).
Hermetically Sealed Drums: Standardized 50kg or 100kg new steel drums designed to withstand pressure changes and physical impact during sea transit.
Inert Gas Protection: Each drum is purged with high-purity Nitrogen (N2) prior to sealing to displace atmospheric air and humidity.
Full Documentation Provided: Every shipment includes full Certificate of Analysis (COA), Safety Data Sheet (SDS / MSDS), UN Packaging Approval, and SGS/BV pre-shipment inspection certificates upon request.
