Description

Poly(Ethylene-Co-Butyl Acrylate) is a thermoplastic elastomer copolymer that combines the toughness and chemical resistance of polyethylene with the flexibility and low-temperature performance of butyl acrylate. This material is valued for its excellent impact strength, flexibility, and weatherability, making it a versatile modifier and base polymer. It is primarily needed by manufacturers in the polymer compounding, wire & cable, and adhesive industries seeking to enhance product durability and processing characteristics.

Application

• As a polymer impact modifier to improve the toughness and low-temperature flexibility of polypropylene (PP) and other rigid plastics.
• Key component in the production of flexible thermoplastic compounds for wire and cable jacketing and insulation.
• Used as a base polymer or additive in the formulation of hot-melt and pressure-sensitive adhesives (HMAs & PSAs).
• As a compatibilizer in polymer blends to improve the miscibility and mechanical properties of multi-component systems.
• Manufacture of extruded and molded articles requiring a balance of flexibility, durability, and chemical resistance.
• Modifier for asphalt and bitumen to enhance elasticity and low-temperature crack resistance in roofing and paving applications.

Quality Control

Our Poly(Ethylene-Co-Butyl Acrylate) is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including comonomer content, melt flow index (MFI), density, and thermal properties to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory 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, consider using under an inert atmosphere to prevent oxidative degradation.
