Description

Alkenes, ethylene-manuf.-by-product C5-cut, oligomers, polymers with ethylene-manuf.-by-product dicyclopentadiene-conc. alkenes and steam-cracked petroleum distillates is a complex hydrocarbon mixture derived from the steam cracking of petroleum naphtha or gas oil, primarily consisting of C5 cut components, oligomers, and polymers. This product matters as a versatile and cost-effective chemical intermediate, offering a unique blend of reactive alkenes and resinous polymers. It is needed by manufacturers in the adhesives, sealants, rubber compounding, and specialty chemical synthesis industries for its tackifying and modifying properties.

Application

• Tackifier and Modifier in Adhesives & Sealants: Enhances tack, peel strength, and flexibility in hot-melt, pressure-sensitive, and construction adhesives.
• Processing Aid and Extender in Rubber Compounding: Improves processability, dispersion of fillers, and can modify the physical properties of synthetic and natural rubber products.
• Intermediate for Hydrocarbon Resins: Serves as a key feedstream for the production of C5 aliphatic and dicyclopentadiene (DCPD)-modified hydrocarbon resins.
• Component in Printing Inks and Coatings: Contributes to viscosity control, gloss, and water resistance in various ink and coating formulations.
• Flow Improver and Compatibilizer: Used in asphalt modification and certain polymer blends to improve compatibility and processing characteristics.
• Feedstock for Chemical Synthesis: The reactive olefinic components can be utilized in further chemical reactions, including alkylation and polymerization.

Quality Control

Our production of this hydrocarbon mixture adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including bromine number, viscosity, color, and softening point to ensure it meets the requirements for downstream resin production and polymer modification. Certificates of Analysis (COA) detailing the specific composition and physical properties are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) when in bulk storage to prevent polymerization and maintain product integrity. Keep container tightly sealed when not in use to minimize evaporation and contact with air.
