Calcium Carbide Market Outlook:
Calcium Carbide Market size was over USD 18.68 billion in 2025 and is anticipated to cross USD 29.57 billion by 2035, growing at more than 4.7% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of calcium carbide is assessed at USD 19.47 billion.
Acetylene gas, which is employed to create polymers such as nylon 66, polyesters, and polyethylene terephthalate (PET), as well as other plastic products, is produced using calcium carbide, which is a frequently utilized component of the process. The increasing demand for plastic products, particularly PVC, nylon 66, and polyesters, can therefore be mostly attributed to market expansion. The global annual output of plastic has grown by around 230 times, i.e. from 2 million tonnes in 1950, reaching 460 million tonnes in 2019. The worldwide production of plastics was over 390 million metric tons in 2021, with a rise of 4% annually.
Furthermore, it is anticipated that increased steel consumption across a number of industries will boost market growth. On account of its exceptional qualities, including durability and ductility, steel is mostly employed in the building and construction industry. It aids in the seismic resistance of buildings. The development of special railroads as a result of an increase in the number of high-speed trains in nations such as China, Japan, and India have increased the need for carbon steel. The need for crude steel is then anticipated to increase, propelling the calcium carbide market. Around 152 million tons (Mt) of crude steel were produced globally in September 2022, an increase of 4% from September 2021.
