Description

Ethylene/Acrylic Acid/Va Copolymer is a versatile, high-performance polymer synthesized from ethylene, acrylic acid, and vinyl acetate monomers. This terpolymer is engineered to deliver a unique balance of adhesion, flexibility, and chemical resistance, making it a critical component in advanced material formulations. It is essential for manufacturers in the packaging, adhesive, coating, and textile industries seeking to enhance product durability and performance.

Application

• Hot Melt Adhesives (HMA): A key polymer for formulating high-performance HMAs used in packaging, woodworking, and non-woven hygiene products due to its excellent adhesion to diverse substrates.
• Flexible Packaging Coatings: Used as a primer or tie-layer resin to improve the adhesion of inks, metals, and other polymers in multi-layer film structures.
• Textile Finishing & Non-wovens: Provides durable binding, water resistance, and soft hand feel in fabric coatings and binder applications for non-woven materials.
• Plastic Modification: Acts as a compatibilizer and impact modifier to enhance the toughness and processability of polyolefin blends and composites.
• Paper & Paperboard Coatings: Imparts moisture barrier properties, grease resistance, and improved surface smoothness for high-quality paper products.
• Sealants and Caulks: Contributes to the flexibility, adhesion, and weatherability of industrial and construction sealants.

Quality Control

Our Ethylene/Acrylic Acid/Va Copolymer is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including monomer content, melt flow index (MFI), acid number, and thermal stability to ensure consistent performance. A Certificate of Analysis (COA) documenting purity, physical properties, and application-specific performance data is available for every shipment.

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 flames. For long-term storage, consider using an inert atmosphere to maintain optimal polymer properties.
