Our high-quality calcium carbide is an essential component in the production of various crucial industrial gases and compounds. It is instrumental in generating acetylene gas, which is vital for manufacturing polyvinyl chloride (PVC), lime nitrogen, and dicyandiamide. Furthermore, it serves as a highly effective desulfurizer in iron and steel production and is widely utilized across the electronics industry and as a teaching reagent. Calcium carbide is a versatile chemical compound, with approximately 60% dedicated to chemical production. The remaining 40% plays a critical role in facilitating metal welding and cutting processes, emphasizing its importance across diverse industrial applications. Harnessing the potential of calcium carbide as a foundational raw material allows for the creation of an extensive array of chemical products. These include PVC resin, polyvinyl alcohol, vinyl acetate, and neoprene rubber, among others. It also enables the production of butanol, octanol, and sophisticated compounds like tricyanoethylene, tetracyanoethylene, as well as acetaldehyde, acetylene carbon black, and lime nitrogen.
