The Types segmentation of the Crude Dicyclopentadiene market distinguishes between pure DCPD, DCPD blends, and DCPD derivatives, each fulfilling distinct functional requirements. Pure DCPD, obtained through fractional distillation of crude streams, serves as the baseline material for polymerization and is valued for its high purity and consistent reactivity; it commands the largest share, roughly 55 % of type‑based consumption. DCPD blends, which incorporate stabilizers, inhibitors, or co‑monomers, are tailored for specific processing conditions in resin and rubber formulations, representing about 30 % of the market. DCPD derivatives—such as hydrogenated DCPD, epoxidized DCPD, and cyclopentadiene‑derived monomers—offer modified physical properties like increased oxidation resistance or altered glass transition temperatures, and they account for the remaining 15 %. Understanding these type categories is essential for accurate Crude Dicyclopentadiene market taxonomy and forecasting demand across differentiated product lines.
