Polypropylene grafting maleic anhydride(MAH) compatibilizer
This product can be used as a surface improver for extruded sheet or extruded sheet, which can effectively improve the surface flatness of sheet or sheet, and eliminate the unevenness and pitting on the surface of the material.
The maleic anhydride moiety in MAPP acts as a polar functional group that can react with or adhere to other polar materials, such as polyamides, polyesters, or cellulose fibers. At the same time, the polypropylene backbone of MAPP retains its nonpolar character and can interact with other nonpolar polymers, such as polyethylene or polybutylene.
Therefore, MAPP can improve the interfacial adhesion and compatibility between dissimilar polymers, reduce the phase separation and mechanical degradation, and enhance the overall properties of the blend or composite, such as stiffness, toughness, impact resistance, or thermal stability.
PP compatibilizer (B1) is prepared by grafting maleic anhydride to polypropylene, because it introduces a strong polar side group (maleic anhydride) into the main chain of polypropylene, so maleic anhydride grafted Polypropylene can be a bridge to improve the adhesion and compatibility of polar and non-polar materials.
In the application of PP+glass fiber modification, it can react with the surface-treated glass fiber to improve the compatibility of PP and glass fiber, thereby improving the tensile strength and impact strength of polypropylene. Adding PP compatibilizer in the production of filled polypropylene can greatly improve the affinity between fillers and polypropylene and the dispersion of fillers.
