Maleic Anhydride Modified Polypropylene as a High Grafting Rate Coupling Agent
COACE's main products are compatibilizers, tougheners and functional additives, which are used in: modified plastics, wood-plastic profiles, low-smoke halogen-free flame-retardant cables, PP extruded sheets, PE extruded sheets, and anti-corrosion pipes Coatings, hot melt adhesives, photovoltaic film additives and other fields, among which special products such as nylon ultra-low temperature toughener, polyester compatible toughener, alloy compatibilizer have reached the domestic advanced level.
B1C is a maleic anhydride modified polypropylene with high grafting rate.
This innovative coupling agent is based on maleic anhydride modified polypropylene, which has been carefully developed for compatibility and reactivity with polypropylene matrices. The modification with maleic anhydride gives the polypropylene reactive functional groups that allow for robust chemical interactions with other components in the material formulation. This higher compatibility and adherence leads to better mechanical properties and overall material performance.
Maleic Anhydride Modification: The addition of reactive functional groups to polypropylene improves its compatibility and adhesion to other materials in composite formulations.
High Grafting Rate: The coupling agent has a high grafting rate, which allows for quick alteration of polypropylene matrices and uniform dispersion within the material, resulting in consistent mechanical properties.
Improved Compatibility: Maleic anhydride-modified polypropylene improves compatibility with other materials, resulting in better dispersion, adhesion, and overall performance.
Enhanced Mechanical qualities: The coupling agent improves mechanical qualities such as tensile strength, impact resistance, and flexural modulus, making it appropriate for a variety of applications.
Maleic anhydride modified polypropylene is widely used in a variety of industries, including automotive, construction, packaging, and electrical, due to its adaptability and performance-enhancing qualities.
Maleic anhydride-modified polypropylene improves the processability of polypropylene formulations, making it easier to handle, mold, and fabricate into final products.
Cost-Effectiveness: The coupling agent's high grafting rate allows for efficient alteration of polypropylene matrices, resulting in cost-effective production processes and competitive pricing for finished goods.
Environmental Sustainability: Maleic anhydride-modified polypropylene compositions are more durable and long-lasting, resulting in less waste and environmental effect during the product's lifetime.
