Description

Polypropylene-Graft-Maleic Anhydride, Av Erage Mw Ca. 9,100 is a chemically modified polypropylene featuring maleic anhydride functional groups grafted onto the polymer backbone. This modification is critical for enhancing the compatibility and adhesion between non-polar polypropylene and polar materials like glass fibers, minerals, and other polymers. It is an essential compatibilizer and coupling agent for manufacturers in the plastics, composites, and coatings industries seeking to improve the mechanical properties and performance of their products.

Application

• Polymer Compatibilizer: Key for improving the interfacial adhesion in polypropylene (PP) blends with polar polymers like polyamide (PA) or polyethylene terephthalate (PET), leading to superior mechanical properties.
• Composite Coupling Agent: Widely used as a coupling agent in glass fiber-reinforced and mineral-filled polypropylene composites to enhance strength, stiffness, and impact resistance.
• Adhesion Promoter: Employed in coatings, inks, and adhesive formulations to promote strong bonding of polypropylene substrates to metals, paints, and other surfaces.
• Reactive Modifier: Used to introduce reactive sites onto the polypropylene chain for further chemical modifications, such as crosslinking or grafting with other functional monomers.
• Packaging Material Enhancement: Improves the barrier properties and printability of polypropylene films and containers in advanced packaging solutions.
• Automotive Components: Critical in the production of high-performance under-the-hood parts, interior trim, and bumper fascias where material compatibility and durability are paramount.

Quality Control

Our Polypropylene-Graft-Maleic Anhydride is manufactured under stringent process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through key parameters including maleic anhydride content, melt flow index (MFI), and molecular weight distribution. Certificates of Analysis (COA) detailing these specifications are provided with every shipment to guarantee compliance with your technical requirements.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent moisture absorption, which can affect performance. Keep away from strong oxidizers and bases.
