Polypropylene grafting maleic anhydride plastic compatibilizer

In the application of PP+glass fiber modification, B2 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.

Maleic anhydride grafted polypropylene (MAPP), also known as polypropylene-graft-maleic anhydride (PP-g-MAH), is a type of polymer that is produced by grafting maleic anhydride onto a polypropylene backbone. The grafting process introduces a highly polar side group (maleic anhydride) into the main chain of polypropylene, which can improve the compatibility and adhesion of polypropylene with polar materials such as wood, metals, and polymers.

MAPP has been widely used as a promoter in various applications. For example, it can be used as a coupling agent in wood-plastic composites (WPCs) to improve the adhesion between the wood fibers and the polypropylene matrix. It can also be used as a compatibilizer in blends of polypropylene with other polar polymers, such as polyethylene terephthalate (PET) or polyamide (PA), to improve their compatibility and mechanical properties.

Overall, the use of MAPP as a promoter is a valuable application of this material that can improve the performance and properties of various materials and products.
