When it comes to sourcing industrial chemical reagents, reliability and seasoned expertise are non-negotiable. Backed by over 15 years of professional manufacturing experience, we take immense pride in supplying our best-selling and most versatile specification: Calcium Carbide (CaC2) 50-80mm medium-to-large lumps. As a golden standard size widely adopted across the global market, this particular grade offers the absolute perfect balance between surface area and prolonged chemical reaction control.

Over the past decade and a half, our factory has perfected its quality control protocols. Every single batch of our 50-80mm Calcium Carbide undergoes rigorous lab testing to guarantee high chemical purity and a superior gas yield reaching up to 300 - 305L/kg. Unlike standard suppliers, our 15+ years of refining our furnace processes ensure that impurities are minimized, resulting in a highly stable, predictable, and clean release of acetylene gas (C2H2). This premium quality translates directly to lower chemical consumption and maximum cost savings for your plant operations.

As the industry's most high-demand particle size, our 50-80mm lumps are incredibly versatile. They are primarily utilized as the backbone for high-capacity industrial acetylene gas generation plants, as a powerful desulfurizer in metallurgical steelmaking foundries, and for generating consistent fuel gas in heavy-duty metal cutting and welding torches.

Because Calcium Carbide reacts violently with ambient air moisture, quality packaging is just as critical as the chemical itself. To eliminate the risk of degradation, we implement a strict, multi-layered hermetic sealing process. Our 50-80mm lumps are packed under a protective nitrogen gas purge into heavy-duty, reinforced steel drums (50kg or 100kg sizes). This state-of-the-art airtight drum filling technology completely insulates the product from external moisture, guaranteeing a prolonged shelf life and safe transoceanic shipping.
