1. Materials Science: Poly-Dicyclopentadiene (PDCPD)
Definition: PDCPD is a cross-linked three-dimensional network engineering plastic, chemically named poly-dicyclopentadiene. Synthesized via ring-opening metathesis polymerization (ROMP) of dicyclopentadiene, it exhibits low density (1.03 g/cm³), high impact strength (Izod notched impact strength: 427 J/m), and exceptional corrosion resistance[2311].
Properties:
· Temperature resistance: −40°C to 120°C
· Chemical resistance: Stable in acids/alkalis (vulnerable to aromatic and halogenated hydrocarbons)
· Glass transition temperature (Tg): 185.5°C
· Suitable for rapid prototyping of complex structures (e.g., reaction injection molding, RIM)[311].
Applications: Automotive components (bumpers), construction machinery, sports equipment housings, chemical-resistant containers, etc.[211].
2. Chemical Industry: Dicyclopentadiene (DCPD)
Definition: A colorless to pale yellow transparent liquid derived from fractional distillation of petroleum cracking by-products. Serves as a foundational feedstock for synthesizing organic compounds like ferrocene and adamantane[715].
Applications:
· Production of petroleum resins, unsaturated polyester resins, and flavor/fragrance compounds
· Raw material for rubber tackifiers, coatings, and adhesives[715].
Processing Characteristics:
· Soluble in alcohols, ethers, and organic solvents
· Requires light-sensitive storage with fire prevention measures
· Transport demands anti-static precautions[7].
