Dicyclopentadiene (DCPD) | High-Performance Resin Monomer | CAS 77-73-6
Overview
Dicyclopentadiene (DCPD) is a clear, colorless to pale yellow liquid with a distinctive, pungent camphor-like odor. Formed by the natural dimerization of cyclopentadiene, it is an extremely versatile reactive monomer featuring two double bonds of unequal reactivity. This unique molecular architecture makes DCPD an indispensable building block for producing a wide array of advanced synthetic resins, specialized elastomers, and high-performance polymers.
Product Description
Dicyclopentadiene (DCPD) | Advanced Resin Monomer
Product Overview
Dicyclopentadiene (DCPD) is a clear, colorless to pale yellow liquid with a distinctive, camphor-like odor. Formed by the dimerization of cyclopentadiene, it is an extremely versatile reactive monomer featuring two double bonds of unequal reactivity. This unique molecular architecture makes DCPD an indispensable building block for producing a wide array of advanced synthetic resins, specialized elastomers, and high-performance polymers.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply bulk volumes of Premium Dicyclopentadiene tailored for the global materials industry. Operating strictly under Class 3 Dangerous Goods protocols, we ensure our DCPD is packaged and transported with absolute securement, guaranteeing optimal reactivity for your polymerization reactors while maintaining strict odor control.
Technical Specifications (COA)
We offer distinct grades tailored for specific industrial applications. Typical specifications for our High-Purity Grade:
| Purity (DCPD) | ≥ 95.0% (99.0% grade available) |
|---|---|
| Cyclopentadiene (CPD) | ≤ 1.0% |
| Moisture / Water | ≤ 0.05% |
| Color (Pt-Co) | ≤ 30 |
| Density (at 20°C) | ~ 0.98 g/cm³ |
Key Applications
- Unsaturated Polyester Resins (UPR): Heavily utilized to modify UPR, enhancing thermal resistance, chemical durability, and surface gloss for marine and construction fiberglass.
- Hydrocarbon Resins: Polymerized to produce premium tackifier resins for hot-melt adhesives, pressure-sensitive tapes, and road-marking paints.
- EPDM Rubber: Serves as a critical precursor for synthesizing the third monomer (ENB) used in EPDM synthetic rubber manufacturing.
- Optical Plastics (COC/COP): High-purity grades are the core feedstock for advanced transparent cyclic olefin copolymers used in lenses and displays.
📈 Lower Costs, Higher Performance in UPR
For Unsaturated Polyester Resin (UPR) manufacturers, replacing traditional phthalic anhydride with Yinglang Chemical's DCPD significantly lowers formulation costs while upgrading performance. DCPD-modified resins exhibit much lower viscosity, better fiberglass wet-out, and dramatically reduced curing shrinkage, resulting in superior composite parts with flawless surface finishes.
Bulk Liquid DG Packaging Options
Because DCPD has a penetrating odor and is flammable, we utilize highly secure packaging for ocean transit:
- ISO TANKS (20 - 24 MT) (Highly recommended for UPR and Hydrocarbon Resin bulk procurement).
- 200 KG Heavy-duty UN-approved Steel Drums (Tightly sealed and Nitrogen-blanketed).
⚠️ Safety & Transport Information (Class 3 DG)
- Transport Classification: Classified as Class 3 (Flammable Liquid).
- UN Number: UN 2048 | Packing Group: III
- Handling Precautions: FLAMMABLE. Has a highly pungent odor. Causes skin and eye irritation. Operators MUST wear half-face respirators and handle in explosion-proof, closed systems to prevent vapor accumulation. Store in a well-ventilated DG facility.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
