High melting point PP compatibilizer

 B1A is prepared by grafting maleic anhydride to polypropylene. Since it introduces a highly polar side group (maleic anhydride) into the main chain of polypropylene, maleic anhydride grafted polypropylene can be used as a promoter The bridge of adhesion and compatibility between polar materials 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 when producing filled polypropylene can greatly improve the affinity between filler and polypropylene and the dispersibility of filler. This is a high melting index PP compatibilizer. Its main feature is that its melting index is higher than that of B1, which can meet the requirements of high melting index for thin-walled products and large parts. This product can be used as a surface improver for extruded sheet or extruded sheet, which can effectively improve the surface flatness of the sheet or sheet, and eliminate the unevenness and pitting on the surface of the material.
