Description

Alkenes, Ethylene-Manuf.-By-Product C5-Cut, Oligomers, Polymers With Ethylene-Manuf.-By-Product Dicyclopentadiene-Conc. Alkenes CAS NO 68131-41-9 is a specialized hydrocarbon mixture derived from the C5 fraction of ethylene manufacturing, enriched with dicyclopentadiene and its oligomers. This product matters as a high-value, reactive chemical intermediate that offers a unique combination of unsaturation and cyclic structures for tailored polymer synthesis and resin modification. It is primarily needed by manufacturers in the petrochemical, specialty polymer, adhesive, and hydrocarbon resin industries seeking to enhance product performance through strategic molecular design.

Application

• Hydrocarbon Resin Production: Serves as a key reactive feedstock for manufacturing C5 aliphatic and dicyclopentadiene (DCPD)-modified hydrocarbon resins used in adhesives, tapes, and rubber compounding.
• Specialty Polymer Modification: Acts as a comonomer or cross-linking agent to introduce cyclic structures and improve the heat resistance, toughness, and adhesion properties of various polymers.
• Synthetic Lubricant Base Stocks: Utilized in the oligomerization and polymerization processes to create high-performance synthetic lubricants and functional fluids.
• Adhesive & Sealant Formulations: Provides tackifying and reinforcing properties in hot-melt, pressure-sensitive, and structural adhesive systems.
• Rubber & Elastomer Compounding: Functions as a plasticizer, tackifier, or reinforcing agent to modify the processing and performance characteristics of synthetic rubbers.
• Fuel & Oil Additives: Used as a precursor for manufacturing deposit control additives, detergents, and viscosity index improvers for fuels and lubricants.
• Chemical Intermediate: Provides a source of reactive alkenes and DCPD for further chemical synthesis, including hydrogenation, epoxidation, and maleinization reactions.
• Printing Inks & Coatings: Contributes to the formulation of resins for inks and industrial coatings, enhancing gloss, hardness, and chemical resistance.

Quality Control

Our Alkenes, Ethylene-Manuf.-By-Product C5-Cut, Oligomers, Polymers With Ethylene-Manuf.-By-Product Dicyclopentadiene-Conc. Alkenes is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability for industrial applications. Key parameters such as dicyclopentadiene concentration, bromine number, and distillation range are rigorously monitored. Certificates of Analysis (COA) detailing specific composition and properties are provided with each shipment to support your quality assurance and production planning.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent evaporation and potential changes in composition. Isolate from strong oxidizing agents.
