Description

Alkenes, Ethylene-Manuf.-By-Product Piperylene-Cut, Polymers With Steam-Cracked Petroleum Distillates is a specialized hydrocarbon resin derived from the polymerization of a piperylene-rich cut obtained as a by-product of ethylene manufacturing. This product matters as a high-performance tackifier and modifier, offering excellent compatibility and solubility in a wide range of hydrocarbon-based systems. It is primarily needed by manufacturers in the adhesives, sealants, rubber compounding, and coatings industries seeking to enhance the performance and processing characteristics of their formulations.

Application

• Pressure-Sensitive Adhesives (PSAs): Acts as a key tackifying resin for tapes, labels, and graphic films.
• Hot-Melt Adhesives (HMAs): Improves tack, peel strength, and open time in packaging and assembly adhesives.
• Rubber Compounding: Used as a processing aid and reinforcing agent in tire treads, belts, and other rubber goods.
• Industrial and Protective Coatings: Enhances drying time, hardness, and chemical resistance.
• Sealants and Caulks: Improves adhesion, flexibility, and durability.
• Printing Inks: Serves as a resinous component to improve gloss, rub resistance, and pigment wetting.
• Asphalt Modification: Used to improve the temperature susceptibility and durability of paving and roofing asphalts.
