Description

Poly(Ethylene) CAS NO 68037-39-8 is a high-molecular-weight polymer of ethylene, characterized by its versatile chain length and branching, which dictate its final material properties. This fundamental polymer is critical for creating materials with a balance of toughness, chemical resistance, and processability. It serves as an essential raw material for manufacturers in the packaging, automotive, construction, and consumer goods industries seeking reliable and consistent polymer performance.

Application

• Polymer Modification & Compounding: Used as a base resin or additive to modify the impact strength, flexibility, and processing characteristics of other polymer blends.
• Film & Packaging Production: A key component in the manufacture of stretch films, shrink wraps, and various flexible packaging materials due to its durability and clarity.
• Adhesive & Sealant Formulations: Imparts tack, cohesion, and water resistance in hot-melt adhesives, sealants, and coatings.
• Wire & Cable Insulation: Provides excellent electrical insulation and environmental stress crack resistance for protective jacketing.
• Masterbatch Carrier: Acts as a primary carrier resin for colorants and functional additives (e.g., UV stabilizers, anti-static agents) in concentrated masterbatches.
• Consumer & Industrial Molded Parts: Utilized in injection molding and blow molding processes to produce containers, caps, housewares, and industrial components.
