Description

Polyethylene-Graft-Maleic Anhydride CAS NO 106343-08-2 is a functionalized polymer where maleic anhydride groups are chemically grafted onto a polyethylene backbone. This modification is critical as it introduces highly reactive anhydride functionality, dramatically improving the polymer's adhesion to polar substrates and its compatibility with other materials. It is an essential additive and compatibilizer for industries requiring enhanced material performance, such as plastics compounding, adhesives, and coatings.

Application

• Compatibilizer in Polymer Blends: Enhances the interfacial adhesion and mechanical properties of blends between non-polar polymers (like polyethylene or polypropylene) and polar polymers (like polyamide or EVOH).
• Adhesive & Tie-Layer Resin: Used as a key component in multilayer film structures (e.g., food packaging, industrial laminates) to bond layers that would otherwise not adhere.
• Fiber & Filler Coupling Agent: Improves the bonding between polyolefin matrices and reinforcing materials like glass fibers, wood flour, or mineral fillers in composite materials.
• Surface Modification: Employed to increase the surface energy and printability of polyolefin films and molded parts.
• Reactive Intermediate: Serves as a platform for further chemical reactions, such as with amines or alcohols, to create custom functional polymers.

Quality Control

Our Polyethylene-Graft-Maleic Anhydride is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance characteristics such as graft level, melt flow index, and thermal stability. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee reliable quality and traceability for your formulations.

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 container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
