Description

Alkenes, Ethylene-Manuf.-By-Product Dicyclopentadiene-Conc., Polymers With Steam-Cracked Petroleum Distillates is a specialized hydrocarbon resin derived from the polymerization of dicyclopentadiene (DCPD)-concentrated streams, a by-product of ethylene manufacturing. This product matters for its unique combination of tackifying properties, thermal stability, and compatibility, offering a cost-effective performance enhancer for various formulations. It is primarily needed by manufacturers in the adhesives, rubber compounding, printing inks, and coatings industries seeking to improve product durability and processing characteristics.

Application

• Adhesive Formulations: Acts as a key tackifier and reinforcing resin in hot-melt, pressure-sensitive, and structural adhesives.
• Rubber Compounding: Used as a processing aid and reinforcing agent to improve the hardness, tensile strength, and aging resistance of synthetic rubbers.
• Printing Inks: Serves as a resinous component to enhance gloss, drying speed, and pigment wetting in various ink systems.
• Protective Coatings: Improves water resistance, adhesion, and film hardness in industrial and marine coatings.
• Tire Manufacturing: Employed in rubber compounds for tires to improve tread wear and rolling resistance.
• Sealants and Caulks: Provides elasticity, adhesion, and durability in construction and automotive sealants.

Quality Control

Our DCPD hydrocarbon resins undergo rigorous quality testing to ensure batch-to-batch consistency and performance reliability for industrial applications. Quality is monitored through key parameters including softening point, color, bromine number, and ash content. Certificates of Analysis (COA) detailing these specifications 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 away from heat sources and open flame. Recommended storage temperature is between 15°C and 30°C (59°F and 86°F). Keep away from strong acids and oxidizing agents. Under these conditions, the product is stable for an extended period.
