Segments

Vinyl and Alumina Applications to Lead Segment Growth

Based on application, the market is segmented into chlorine and caustic soda applications. The vinyl segment dominates the global market in terms of chlorine consumption, as chlorine derivatives are prominently used in PVC production. For caustic soda, the alumina segment leads market growth, driven by the increasing use of aluminum in the automotive industry.

Membrane Cell Technology to Dominate the Market Due to Environmental Benefits

By production technology, membrane cell technology is prominently used, accounting for a fourth-fifth of the total installed production capacity of chlor alkali around the world. This technology is preferred as manufacturers are converting from older mercury cell processes to greener technologies due to rising environmental concerns and regulations.

Drivers & Restraints

Rising Demand for Vinyl Polymers to Augment Market Growth

The thriving construction industry in emerging countries has boosted the demand for chlorine in vinyl production. PVC, the world’s third-largest used polymer, is prominently used to make pipes, window frames, and other products. The emergence of electric vehicles is also likely to boost the consumption of PVC and the chlorine used in vinyl, driving the market.However, the market is exposed to various stringent environmental regulations. Mercury cell production technology has a high risk of polluting water bodies, compelling lawmakers to implement strict regulations on such processes. This may confine the market growth.

Regional Insights

Strong Industrial and Chemical Manufacturing Propels Market Growth in Asia Pacific

Asia Pacific holds the dominant chlor alkali market share and is projected to experience continued growth. The region’s growth is attributed to strong industrial and chemical manufacturing activity, particularly in China, which dominates with over 70% share in regional consumption. Strong growth in the construction industry has boosted chlorine demand, while the adoption of aluminum in the automotive sector has driven caustic soda demand.North America held the second-largest market share. As one of the largest exporters of chlor alkali products, its growth is supported by a resurgent construction industry, which is likely to boost the production of PVC and the demand for chlorine.

Competitive Landscape

Leading Players Focus on Expanding Production Capacities to Meet Demand

The market is fairly fragmented, with continuous capacity additions by leading global and regional players in response to surging demand. The growing demand is set to outnumber the presently installed capacity figures over the long term, creating the need for more capacities in the coming years. Many players have already started to expand their capacities and are evaluating further expansions to meet future demand.
