Description

Poly(Ethylene-Co-Methyl Acrylate) is a flexible, thermoplastic copolymer that combines the toughness of polyethylene with the enhanced flexibility, clarity, and adhesion properties imparted by methyl acrylate comonomer. This material is valued for its excellent low-temperature flexibility, impact resistance, and compatibility with a wide range of substrates. It is primarily sought after by manufacturers in the packaging, wire & cable, and polymer modification industries for applications requiring a soft, durable, and processable material.

Application

• Flexible Packaging Films: Used as a sealant or modifier layer to improve toughness, clarity, and low-temperature performance in food and industrial packaging.
• Wire & Cable Insulation/Jacketing: Provides excellent flexibility, stress-crack resistance, and electrical insulation properties.
• Polymer Modification: Acts as an impact modifier and compatibilizer in polyolefin blends to enhance toughness and flexibility.
• Adhesives & Sealants: Serves as a base polymer in hot-melt and pressure-sensitive adhesives due to its good adhesion and low melt viscosity.
• Automotive Components: Utilized in soft-touch interior parts, gaskets, and seals where flexibility and durability are required.
• Medical Tubing & Film: Selected for its clarity, flexibility, and compliance in non-critical medical device applications.

Quality Control

Our Poly(Ethylene-Co-Methyl Acrylate) is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance in key parameters such as melt index, methyl acrylate content, density, and thermal properties. Certificates of Analysis (COA) detailing lot-specific results are available upon request to support your quality assurance and regulatory compliance needs.

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, a nitrogen blanket is recommended to prevent potential oxidation.
