Premium Acetylene Carbide for Global Industrial Applications
Welcome to the leading china calcium carbide manufacturing and exporting hub. As a premier, direct-to-market calcium carbide factory with over fifteen years of dedicated foreign trade experience, we have established a highly resilient and reliable supply chain that partners with industrial buyers across Southeast Asia, Africa, South America, the Middle East, and Australia. We specialize in producing and distributing high-grade acetylene carbide (CaC2), serving as the foundational cornerstone for acetylene gas generation, steelmaking desulfurization, PVC manufacturing, and chemical synthesis worldwide.

Our industrial-grade acetylene carbide is manufactured in state-of-the-art electric arc furnaces utilizing abundant, high-quality limestone and coke raw materials. This precise production process guarantees a high gas yield that consistently exceeds 295 L/KG, meeting and surpassing international standard levels.
To satisfy the diverse requirements of different global B2B sectors, our calcium carbide factory provides comprehensive grain size customization. Among our most highly demanded products is the calcium carbide 50 80mm lump size, which is widely recognized for its optimal and steady gas-releasing speed. Whether you need small-sized powder (0-2mm, 2-4mm) for high-efficiency desulfurization in the steel-making industry or specific lump sizes for large-scale chemical reactors, we have the manufacturing capabilities to customize the dimensions according to your specific project needs.

As an established leader in the china calcium carbide sector, we deeply understand that safety, stability, and moisture prevention are critical for international maritime transport. To ensure absolute product stability during long sea voyages, we provide robust, customized packaging solutions:
Premium Quality Containers: We supply brand-new 50 kg and 100 kg heavy-duty iron drums.
Nitrogen-Filled Technology: All drums are tightly sealed and nitrogen-filled to completely isolate moisture and prevent degradation.
Flexible Aesthetics: We offer custom drum colors, including professional black, grey, green, yellow, and blue.
Custom Shipping Marks: We can seamlessly print your specific company details, logos, and handling instructions directly on the drums to streamline your warehousing and distribution.

Choosing the right china calcium carbide partner means balancing competitive pricing with absolute product consistency. Because we operate as a direct calcium carbide factory, we completely eliminate middleman markups, allowing us to quote the most competitive wholesale cost per kg.
Furthermore, our extensive infrastructure allows us to maintain massive, consistent stocks year-round. This operational capacity means we can guarantee quick shipping and rapid dispatch times even during peak market seasons.
