High Grafting Rate Coupling Agent for Polypropylene Compounds
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.
Coace ® B1-2 is a maleic anhydride modified polypropylene with high grafting rate.
The high grafting rate coupling agent, based on maleic anhydride modified polypropylene, provides a number of benefits to polypropylene compounds. Its ability to improve compatibility, graft efficiently, improve mechanical qualities, and provide heat resistance makes it an excellent choice for a wide range of applications. The coupling agent is widely used in the automotive, electrical, consumer products, packaging, and industrial industries. Its exceptional processability guarantees that production operations run smoothly and efficiently.
Enhanced compatibility: The high grafting rate coupling agent improves compatibility with polypropylene and other materials. By integrating maleic anhydride modified polypropylene, it efficiently boosts interfacial bonding and improves adhesion between polypropylene and various fillers, reinforcements, and additives. This higher compatibility results in better mechanical characteristics and overall performance of polypropylene composites.
The coupling agent's high grafting rate allows for efficient bonding and grafting onto the polypropylene matrix. The maleic anhydride alteration allows for a robust chemical interaction with the polypropylene chains, resulting in a high level of grafting. This grafting procedure improves the compatibility and interfacial adhesion of the polypropylene compound, resulting in higher mechanical strength, heat resistance, and dimensional stability.
Using a high grafting rate coupling agent enhances the mechanical characteristics of polypropylene composites. By improving interfacial adhesion and compatibility, it enhances the compound's overall structure. This results in higher tensile strength, impact resistance, and flexural modulus, making it ideal for high-performance applications like as automotive components, appliances, and industrial parts.
Maleic anhydride modified polypropylene in the coupling agent improves heat resistance for polypropylene composites. It enhances thermal stability and decreases heat-induced degradation of the material. This feature maintains the compound's integrity and performance in high-temperature applications, making it ideal for use in automobile under-the-hood components, electrical appliances, and industrial applications.
