Dicyclopentadiene Market Size

The global dicyclopentadiene market size was valued at USD 1.73 billion in 2025 and is projected to grow from USD 1.82 billion in 2026 to USD 2.78 billion by 2034, registering a CAGR of 5.4% during the forecast period from 2026 to 2034. Asia Pacific dominated the dicyclopentadiene market with a market share of 42.3% in 2025.

Dicyclopentadiene, or DCPD, is a substance with the chemical formula C10H12. A petrochemical by-product of ethylene is dicyclopentadiene. DCPD is used as a chemical intermediary in the production of some resins and pesticides. Additionally, it is utilized to create paints, varnishes, and plastic flame retardants. DCPD pollutes the air, water, and soil when produced, used, transported, or discarded into the environment. Short-term exposure to DCPD at 1 to 5 parts per million (ppm) has been associated with eye, skin, and throat discomfort. The lungs, kidneys, and nervous system may suffer adverse effects from repeated, prolonged exposure.

The exterior bodies of cars, trucks, and other machines, as well as vehicle coverings like hoods and shields, are made of DCPD resin because of their unique properties. The product is favored over thermoplastic polymer in the automotive industry and other industries because it solves automotive problems and reduces costs on the assembly line by consolidating parts. In the marine and caustic or chlorine industries, DCPD is used for cell cover because it does not corrode. Due to its superior electrical insulation, low thermal conductivity, and complete chemical inertness to reactants and products, its use in the marine industry will also rise.

Grade Insight

The polyester grade segment is the highest contributor to the market and is anticipated to grow at a CAGR of 5.5% over the forecast period. Polyester-grade dicyclopentadiene is specifically used in the production of unsaturated polyester resins. It is generally 75–85% pure and contains less than 0.1% DCPD trimers by weight. It has good color qualities and almost no tendency to form gel particles that can clog spraying equipment and filters used to make polyester products. In the future, the demand for polyester-grade dicyclopentadiene is likely to be driven by the growing need for unsaturated polyester resins in making different kinds of plastic products.

Dicyclopentadiene, made from hydrocarbons, is usually considered a highly reactive intermediate that can react with many different monomers. As a result, it is primarily used to produce various hydrocarbon resins, such as C5 and C9 aliphatic and aromatic resins. In order to reduce the tackyfying effect in paint, printing ink, adhesives, and rubbers, hydrocarbon resins are primarily used. As a result, the future expansion of this market segment should be bolstered by the rising interest in these goods.

Application Insight

The unsaturated polyester resin segment is the highest market and is anticipated to grow at a CAGR of 5.61% over the forecast period. Dicyclopentadiene is often used to make unsaturated polyester resins because it doesn't shrink or contain much styrene. Unsaturated polyesters are the third-largest class of thermoset molding resins. These typically create filled and fiber-reinforced plastics, such as pipes, storage tanks, and bathroom fixtures. In addition, fiber-reinforced plastics are used in the automotive and shipping industries to fabricate various body parts, such as fenders, body panels, and hulls. The unsaturated polyester resins are also used to make different coatings and glues. The growing demand for unsaturated polyester resins in the above uses will likely be good for the global dicyclopentadiene (DCPD) market.

Hydrocarbon resins are a type of thermoplastic polymer that is made by polymerizing unsaturated hydrocarbons. They are amorphous and do not have crystals. C5 aliphatic, C9 aromatic, and DCPD cycloaliphatic are the three main types of hydrocarbon resins. These resins are used in numerous types of rubber, coatings, printing inks, and glues. Hydrocarbon resins help improve the tack and peel strengths of the rubber adhesives. On the contrary, coatings provide superior pigment wetting, enhanced adhesion, gloss, and film hardness attributed to the end products.
