Description

Poly(Ethylene-Co-Methacrylic Acid) is a versatile ionomer precursor and copolymer known for its excellent adhesion, toughness, and compatibility with various substrates. This material is valued for its ability to be neutralized with metal ions to form durable, clear films with enhanced mechanical and barrier properties. It is essential for manufacturers in the packaging, automotive, and specialty polymer industries seeking to improve product performance and processability.

Application

• Packaging Films: Used as a heat-seal layer and tie layer in multi-layer films for food and medical packaging due to its strong adhesion and clarity.
• Coating & Lamination: Serves as a primer or adhesive coating for metals, papers, and other polymers, providing excellent bond strength.
• Automotive Components: Employed in interior trim, gaskets, and under-the-hood parts for its impact resistance and durability.
• Wire & Cable Insulation: Acts as a halogen-free flame-retardant component and insulation layer.
• Polymer Modification: Used as an impact modifier and compatibilizer in polymer blends and composites.
• Hot Melt Adhesives: Provides high-performance bonding with good thermal stability and adhesion to difficult substrates.

Quality Control

Our Poly(Ethylene-Co-Methacrylic Acid) is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in key parameters such as methacrylic acid content, melt flow index, and thermal properties. Certificates of Analysis (COA) detailing lot-specific results 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 strong oxidizing agents and bases. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
