Description

Alkenes, Ethylene-Manuf.-By-Product Piperylene-Cut, Polymd. is a polymeric hydrocarbon resin derived from the piperylene-rich cut of ethylene manufacturing by-products. This material matters as a versatile tackifier and modifier, offering excellent compatibility and performance enhancement in adhesive and sealant formulations. It is primarily needed by manufacturers in the pressure-sensitive adhesive, hot-melt adhesive, rubber compounding, and coating industries seeking to improve tack, peel strength, and cohesive properties.

Application

• Pressure-Sensitive Adhesives (PSAs): Acts as a key tackifying resin for labels, tapes, and graphic films.
• Hot-Melt Adhesives (HMAs): Used to enhance open time, tack, and specific adhesion in packaging, woodworking, and non-woven applications.
• Rubber Compounding: Serves as a processing aid and reinforcing agent in tire and industrial rubber goods manufacturing.
• Sealants and Caulks: Improves adhesion, flexibility, and durability in construction and automotive sealants.
• Printing Inks: Functions as a resinous component to improve gloss, rub resistance, and pigment wetting.
• Industrial Coatings: Modifies properties such as drying time, hardness, and chemical resistance.

Quality Control

Our Alkenes, Ethylene-Manuf.-By-Product Piperylene-Cut, Polymd. is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including softening point, color, acid number, and bromine number to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting these specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product quality.
