The naphthalene market is a key segment within the petrochemical industry, driven by its role in producing a range of chemicals and materials. Naphthalene, a white crystalline aromatic hydrocarbon derived from coal tar or petroleum, is widely used as an intermediate in the manufacture of phthalic anhydride, naphthalene sulfonates, dyes, resins, and other chemical compounds. The market is shaped by industrial demand in sectors such as construction, agriculture, pharmaceuticals, textiles, and consumer products, where naphthalene’s properties make it valuable for enhancing product quality, durability, and performance.

The naphthalene market size was valued at USD 0.36 billion in 2023 and is projected to grow from USD 0.37 billion in 2024 to USD 0.48 billion by 2032, exhibiting a compound annual growth rate (CAGR) of 3.19% during the forecast period (2024–2032).

Key Market Drivers

  • High Demand for Phthalic Anhydride: Phthalic anhydride, a key derivative of naphthalene, is widely used in the production of plasticizers, dyes, and pigments, as well as in coatings and polyvinyl chloride (PVC) production. Rising construction and infrastructure development activities ly drive demand for phthalic anhydride-based products like plasticizers and resins, which in turn fuels demand for naphthalene.

  • Growing Construction Sector: Naphthalene-based compounds, particularly naphthalene sulfonates, are commonly used as superplasticizers in the concrete industry. These superplasticizers improve the fluidity and workability of concrete mixtures without compromising strength, making them ideal for modern construction requirements. Rapid urbanization, industrialization, and infrastructure investments are expanding the construction sector, which, in turn, is boosting demand for naphthalene-based superplasticizers.

  • Agricultural Applications: Naphthalene derivatives are also used in the agricultural sector for pesticide and insect repellent production. As demand for crop protection products rises to meet the needs of an expanding population, the agricultural sector increasingly relies on naphthalene derivatives for effective pest control solutions.

  • Pharmaceutical Applications: Naphthalene derivatives are used in the synthesis of certain pharmaceutical intermediates. While this represents a smaller portion of the market, pharmaceutical applications contribute to a stable demand for naphthalene, especially as new applications emerge in chemical synthesis for medical purposes.

Key players in the naphthalene companies are Koppers Inc. (US), Merck KGaA (Germany), BASF SE (Germany), Industrial Química del Nalón S.A. (Spain), PCC Rokita SA (Poland), Carbon Tech & Sepahan Chimie complex (Iran), DEZA a. s. (Czech Republic), Compro Shijiazhuang Fine Chemical Co (China), Rain Carbon Inc.(India), Wuxi Kinghan Bio-Medical & Chemical Inc. (China)

Market Challenges

  • Environmental and Health Concerns: Naphthalene is known for its environmental impact and potential health hazards, particularly due to its high volatility and toxicity. Many countries impose strict regulations on the production and use of naphthalene, particularly in applications that may impact public health, such as in household products. These regulations can impact production methods and limit certain applications, leading to higher compliance costs.

  • Price Volatility: Naphthalene production is closely linked to the availability and price of its raw materials, primarily coal and petroleum. Fluctuations in crude oil prices, as well as geopolitical issues affecting raw material supply, can lead to price volatility, impacting production costs and pricing strategies within the market.

  • Substitution by Alternative Chemicals: Increasing environmental awareness and the search for sustainable alternatives are leading some industries to explore other compounds in place of naphthalene. For example, industries that rely on superplasticizers or dye intermediates may look for alternative chemical solutions with lower environmental impact. This substitution trend could potentially limit the market’s growth.
