Description

Alkenes, Ethylene-Manuf.-By-Product Dicyclopentadiene-Conc., Polymers With Ethylene-Manuf.-By-Product Piperylene-Cut Alkenes is a specialized hydrocarbon resin derived from the co-polymerization of concentrated dicyclopentadiene and piperylene-rich streams, which are by-products of ethylene manufacturing. This product matters for its ability to provide excellent tackifying, adhesive, and reinforcing properties in polymer formulations, offering a cost-effective and sustainable solution by valorizing industrial by-products. It is primarily needed by manufacturers in the adhesives, sealants, rubber compounding, and road marking industries seeking to enhance product performance and optimize raw material costs.

Application

• Hot-Melt Adhesives (HMA): Acts as a key tackifier and modifier, improving adhesion, flexibility, and thermal stability.
• Pressure-Sensitive Adhesives (PSA): Enhances tack, peel strength, and cohesion in tapes and labels.
• Rubber Compounding: Used as a reinforcing resin and processing aid in tire treads, belts, and other rubber goods.
• Road Marking Paints & Traffic Coatings: Imparts durability, quick-drying properties, and retro-reflectivity.
• Printing Inks: Serves as a resinous component to improve gloss, rub resistance, and pigment wetting.
• Sealants & Caulks: Provides elasticity, adhesion, and resistance to weathering and chemicals.
• Industrial Coatings: Used in protective and marine coatings for enhanced water resistance and film integrity.
• Polymer Modification: Functions as a compatibilizer and impact modifier in various thermoplastic and thermoset systems.

Quality Control

Our hydrocarbon resins are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of tests including softening point, color, bromine number, and acid number. Certificates of Analysis (COA) documenting all key parameters are available for every shipment. Our quality management system adheres to ISO 9001 standards, and our products comply with relevant global regulations including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperatures (15-25°C). Keep away from heat sources and open flames. For long-term storage, an inert atmosphere (nitrogen blanket) is recommended to prevent oxidation and maintain product color stability.
