COUPLING AGENT MAPP 9012 GA

COUPLING AGENT MAPP 9012 GA

COUPLING AGENT MAPP 9012 GA is a polypropylene-based coupling agent functionalized with maleic anhydride (MAPP), specifically developed to improve the interfacial adhesion between polypropylene (PP) and glass fibers in reinforced PP compounds. It is suitable for both short and long glass fiber reinforced polypropylene applications, delivering enhanced mechanical performance while maintaining excellent processing characteristics.

Key Features

• Maleic anhydride grafted polypropylene (MAPP) coupling agent.
• Improves adhesion between polypropylene matrix and glass fibers.
• Enhances tensile strength, impact resistance, and overall mechanical properties.
• Highly effective at low addition levels.
• Does not promote discoloration during processing.
• Supplied in easy-to-process granule form.

Typical Properties

• Composition: Polypropylene functionalized with maleic anhydride.
• Melt Flow Rate (190°C / 2.16 kg): 50–110 g/10 min.
• Drying Loss (3 hours at 110°C): <0.5%.
• Maleic Anhydride (MAH) Content: >0.9%.
• Form: Granules.

Applications

• Short glass fiber reinforced polypropylene compounds.
• Long glass fiber reinforced polypropylene compounds.
• Automotive components.
• Electrical and electronic parts.
• Industrial engineering plastic compounds.
• High-performance reinforced PP applications.

Recommended Processing

The recommended dosage is 0.5–2.0% of the total formulation, depending on the glass fiber loading. For optimum performance, add the product through the main feed during compounding and ensure proper wetting of the glass fibers. The ideal dosage should be determined through laboratory trials.

Storage

Store in a cool, dry place below 35°C with relative humidity below 80%. Protect the material from direct sunlight and moisture to maintain product quality.
