Description

Polypropylene-Graft-Maleic Anhydride is a functionalized polyolefin where maleic anhydride is chemically grafted onto a polypropylene backbone. This modification is critical as it introduces highly reactive anhydride groups, transforming the non-polar polypropylene into a material with excellent adhesion and compatibility properties. It is an essential compatibilizer and coupling agent for engineers and formulators in the polymer compounding, automotive, and packaging industries seeking to create high-performance composite materials.

Application

• Polymer Compatibilizer: Enhances the interfacial adhesion and dispersion of fillers (like glass fiber, talc, wood flour) and polar polymers (like PA, PET) within polypropylene matrices.
• Adhesion Promoter: Used as a primer or additive in coatings, inks, and adhesives to improve bonding to polyolefin surfaces, which are typically difficult to adhere to.
• Reactive Modifier: Serves as a key intermediate for further chemical reactions, enabling the synthesis of specialized polymers with tailored properties.
• Composite Manufacturing: Crucial for producing high-strength, lightweight composites in automotive parts, consumer goods, and industrial components.
• Packaging Films: Used in multilayer film structures to improve layer adhesion between PP and barrier materials like EVOH or nylon.
• Wood-Plastic Composites (WPC): Improves the mechanical properties and moisture resistance of WPCs by enhancing the bond between wood fibers and the PP matrix.
• Cable & Wire: Acts as a coupling agent in halogen-free flame retardant (HFFR) cable compounds to improve filler dispersion and mechanical performance.

Quality Control

Our Polypropylene-Graft-Maleic Anhydride is manufactured under a stringent quality management system. Each batch undergoes rigorous testing for key parameters including maleic anhydride content, melt flow rate (MFR), and thermal stability to ensure consistent performance. Certificates of Analysis (COA) detailing the specific grade's properties are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); keep the original container sealed to prevent moisture absorption, which can affect performance.
