Description

Polycyclopentadiene CAS NO 68132-00-3 is a high-purity, synthetic hydrocarbon resin derived from the polymerization of cyclopentadiene. This versatile material is valued for its excellent thermal stability, adhesive properties, and chemical resistance, making it a critical intermediate and additive in advanced manufacturing. It is essential for industries requiring high-performance resins, tackifiers, and modifiers for coatings, adhesives, and rubber products.

Application

• Hydrocarbon Resin Production: Serves as a key monomer and feedstock for manufacturing C5 aliphatic and cycloaliphatic hydrocarbon resins.
• Adhesives & Sealants: Used as a tackifier and modifier to enhance adhesion, cohesion, and thermal performance in hot-melt and pressure-sensitive adhesives.
• Rubber Compounding: Acts as a processing aid and reinforcing agent in tire manufacturing and industrial rubber goods to improve durability and aging resistance.
• Printing Inks: Employed as a resin component to improve gloss, rub resistance, and drying properties in gravure and flexographic inks.
• Protective Coatings: Functions as a modifying resin in paints and varnishes to enhance water resistance, hardness, and weatherability.
• Road Marking Paints: A vital component in thermoplastic road marking paints, providing fast setting times and excellent reflectivity.
• Specialty Polymers: Utilized as a cross-linking agent or comonomer in the synthesis of specialty polymers and engineering plastics.

Quality Control

Our Polycyclopentadiene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, molecular weight distribution, and performance characteristics. Certificates of Analysis (COA) documenting key parameters such as softening point, color, and bromine number are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, consider using under an inert atmosphere to prevent oxidation and maintain product integrity.
