Description

Poly(Ethylene-Co-Acrylic Acid), Zinc Salt is an ionomer derived from the partial neutralization of an ethylene-acrylic acid copolymer with zinc ions. This material is valued for its unique combination of thermoplastic processability and enhanced mechanical properties, including improved toughness, adhesion, and clarity. It serves as a critical performance additive and base polymer for manufacturers in the packaging, automotive, and specialty compounding industries seeking to improve product durability and functionality.

Application

• Hot Melt Adhesives & Sealants: Acts as a key tackifier and rheology modifier, providing excellent adhesion to polar substrates like metals and treated plastics.
• Polymer Modification & Compatibilization: Used as an impact modifier and compatibilizer in polymer blends (e.g., polyolefin/nylon) to enhance toughness and interfacial adhesion.
• Coating Resins: Imparts superior abrasion resistance, chemical resistance, and adhesion in protective and decorative coatings for metals and plastics.
• Packaging Films: Utilized in multilayer film structures for its excellent sealability, clarity, and grease resistance, particularly in food and medical packaging.
• Wire & Cable Insulation: Enhances the thermal stability, flame retardancy, and mechanical strength of insulation and jacketing compounds.
• Masterbatch Carrier: Serves as an efficient carrier resin for color and additive masterbatches due to its good dispersion characteristics and compatibility.

Quality Control

Our Poly(Ethylene-Co-Acrylic Acid), Zinc Salt is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in melt flow index, acid neutralization level, zinc content, and thermal stability. Certificates of Analysis (COA) documenting key physical and chemical parameters are provided to guarantee the material meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the original container sealed when not in use to prevent moisture absorption, which can affect processing and performance.
