Coace® B1-2 is a maleic anhydride modified polypropylene with high grafting rate.
The high grafting rate coupling agent for composites, based on maleic anhydride modified polypropylene, has several benefits for improving composite material adherence and compatibility. Its main features are maleic anhydride modification, a high grafting rate, better adhesion, compatibility, adaptability, heat stability, and improved mechanical qualities.
The benefits of using this coupling agent include increased adhesion, compatibility, mechanical characteristics, reduced friction and wear, improved processing, and the ability to modify formulations for specific applications.
Maleic Anhydride Modification: The coupling agent is made from polypropylene modified with maleic anhydride. This modification introduces reactive functional groups, such as carboxyl and anhydride, which promote strong bonding with a variety of materials.
This coupling agent stands out for its high grafting rate, which relates to how many maleic anhydride units are grafted onto the polypropylene backbone. A high grafting rate increases the number of reactive sites accessible for bonding, which leads to better adhesion and compatibility.
Maleic anhydride modification improves the adhesion qualities of the coupling agent. When used in composite materials, it establishes strong connections with fillers, reinforcements, and polymer matrix, resulting in good interfacial adhesion.
The coupling agent enhances compatibility between incompatible materials, including polypropylene and fillers or reinforcements. It promotes improved mixing and dispersion, which helps to prevent phase separation and enhances composite homogeneity.
This coupling agent is versatile and compatible with many polymers, fillers, and reinforcements. It can be utilised in a variety of composite systems, including polypropylene-based composites, to improve mechanical characteristics and performance.
The modified polypropylene is heat stable and suited for applications requiring thermal resistance. This ensures that the coupling agent remains effective even under demanding processing circumstances.
Maleic anhydride modified polypropylene has a high grafting rate, leading to enhanced adhesion between the coupling agent and composite materials. This results in better mechanical qualities including tensile strength and impact resistance.
The coupling agent enhances the compatibility of polypropylene with fillers or reinforcements, resulting in more consistent and homogeneous composites. As a result, materials have more consistent characteristics and are less likely to have faults.
Improved Mechanical characteristics: The coupling agent improves adhesion and compatibility, leading to better mechanical characteristics for composite materials. These include enhanced stiffness, toughness, and fatigue resistance, which qualifies the composites for structural applications.
The coupling agent reduces friction between composite components, making it suitable for applications requiring low friction and wear resistance. This produces materials that can sustain sliding or abrasive wear without premature failure.
