Description

Alkenes, Ethylene-Manuf.-By-Product Dicyclopentadiene-Conc., Polymd. is a concentrated, polymerized derivative of dicyclopentadiene (DCPD), a key by-product from ethylene manufacturing. This material matters for its role as a versatile, high-performance hydrocarbon resin precursor, offering excellent thermal stability and chemical resistance. It is primarily needed by manufacturers in the petrochemical, polymer, and specialty chemical industries for producing resins, adhesives, and coatings.

Application

• Primary feedstock for the production of hydrocarbon resins (C5/C9 types) used in adhesives, tapes, and rubber compounding.
• Key intermediate in the synthesis of unsaturated polyester resins (UPR) for the marine and construction sectors.
• Essential component in the formulation of high-performance, thermosetting coatings and inks.
• Used as a modifier and cross-linking agent in elastomers and engineering plastics to enhance heat and chemical resistance.
• Employed in the manufacture of flame retardants and other specialty additives.
• Serves as a valuable starting material for fine chemical synthesis in the agrochemical and pharmaceutical industries.

Quality Control

Our Alkenes, Ethylene-Manuf.-By-Product Dicyclopentadiene-Conc., Polymd. undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Production is monitored against key parameters including viscosity, softening point, and bromine number. Certificates of Analysis (COA) detailing purity and physical specifications are available upon request.

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/59-77°F). As this product is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
