Report Overview

The Global Indene (CAS 95-13-6) Market size is expected to be worth around USD 359.5 million by 2034, from USD 222.8 million in 2024, growing at a CAGR of 4.9% during the forecast period from 2025 to 2034.

Indene, a polycyclic aromatic hydrocarbon with the molecular formula C₉H₈ and molecular weight 116.16, is also known as benzocyclopentene. Naturally present in coal tar and crude oil, indene is also emitted during the incomplete combustion of fossil fuels. It is a colorless liquid that does not readily volatilize but turns yellow upon standing and decolorizes in sunlight, with a melting point of –1.8 °C, boiling point of 182.6 °C, flash point of 58 °C, and relative density of 0.9960 (25/4 °C).

Indene is insoluble in water but miscible with ethanol and ether. The molecule exhibits low toxicity and minimal irritation to skin and mucous membranes. Its highly reactive olefinic double bond makes it prone to polymerization and addition reactions; it polymerizes slowly at room temperature, with the rate increasing sharply upon heating or in the presence of acid catalysts, yielding secondary indene resin when treated with concentrated sulfuric acid.

• The Indene (CAS 95-13-6) is closely tied to demand for indene-coumarone resins used in coatings, rubber processing, adhesives, and inks. The key feedstock fraction distilled at 160–215°C contains approximately 40% indene, along with styrene and coumarone derivatives, forming 60–70% of total resin raw material inputs.

Indene is typically supplied as a colourless to pale yellow liquid with purity levels of ≥97% and registered under EINECS 202-393-6. Demand is further supported by its predictable physicochemical behavior, consistent polymer quality, and efficient integration into hydrocarbon resin value chains.

Indene shows low toxicity and limited skin or mucous membrane irritation, which improves its acceptability in industrial chemical formulations. ECHA data highlights its relative density of 0.9960 at 25°C, insolubility in water, and miscibility with ethanol or ether. Importantly, the molecule contains chemically active olefin bonds, enabling polymerization and addition reactions critical for resin chemistry.

Emerging Trends

Shift Toward High-Purity and Performance Resins Shapes Market Trends

One major trend in the indene market is the growing preference for high-purity grades. End users increasingly demand consistent quality to meet performance standards in coatings, inks, and rubber products. This pushes producers to adopt better refining and quality control practices.

• There is also a clear trend toward performance-focused resin formulations. Manufacturers are blending indene-based resins with other polymers to improve flexibility, adhesion, and thermal resistance. The International Energy Agency (IEA) reports that global refinery capacity upgrading investments exceeded USD 60 billion between 2021 and 2024, supporting better recovery of specialty aromatics such as indene.

Regional production expansion in Asia is shaping trade patterns. Countries with strong refining and chemical bases are becoming key suppliers, while others rely on imports. Overall, the market is evolving toward efficiency, better quality, and application-driven product development.

Drivers

Strong Demand for Coumarone–Indene Resins Drives Market Growth

Indene demand is strongly driven by its wide use in making coumarone–indene resins. These resins are used in paints, coatings, adhesives, rubber compounding, and printing inks. As construction and infrastructure activities increase, demand for durable coatings and adhesives rises steadily. This directly supports stable consumption of indene.

• The rubber industry is another strong driver. Indene-based resins improve tackiness, heat resistance, and flexibility in tires and industrial rubber products. The International Rubber Study Group (IRSG), global rubber consumption exceeded 29 million metric tons in 2023, driven by automotive and industrial demand.

Indene is also used as an intermediate in specialty chemicals and agrochemicals. Expanding chemical manufacturing capacity in Asia supports long-term consumption. Additionally, its availability from coal tar and petroleum streams ensures a continuous supply, which helps producers maintain steady output and pricing stability in the market.

Restraints

Dependence on Petroleum and Coal Tar Limits Market Expansion

A key restraint for the indene market is its heavy dependence on petroleum refining and coal tar processing. Any disruption in crude oil supply, refinery shutdowns, or changes in fuel demand directly affect indene availability. This makes supply planning challenging for manufacturers and downstream users.

• Environmental and safety regulations present another restraint. Indene is classified as an aromatic hydrocarbon, and its handling requires strict compliance with workplace safety and emissions norms. Digital upgrades can improve by-product yield recovery by 3–5%, making indene extraction more economically attractive without new crude inputs.

Price volatility is also a concern. Fluctuations in crude oil and coal tar prices increase raw material uncertainty, which impacts profit margins. In addition, the availability of alternative hydrocarbon resins can reduce dependence on indene in certain applications, slowing market growth.

Growth Factors

Expansion of Specialty Chemicals Creates New Growth Opportunities

Growth opportunities for the indene market are emerging from the expansion of specialty chemical manufacturing. Increasing demand for high-performance resins in electronics, industrial coatings, and infrastructure projects opens new application areas for indene-based materials.

Developing economies are investing heavily in construction, transportation, and industrial infrastructure. This creates rising demand for adhesives, sealants, and protective coatings where indene-derived resins are widely used. Local chemical production growth further supports regional indene consumption.

Another opportunity lies in process optimization and recovery technologies. Improved extraction from refinery by-products can enhance yield and cost efficiency. Producers focusing on purity improvement and customized grades can target niche applications, creating higher-value growth segments within the indene market.
