Enhancing the Properties of PP GF
Polypropylene (PP) is a non-polar polymer, which often results in poor surface bonding with glass fibers, limiting the material's performance. However, AAP's coupling agent - ENP (Maleic Anhydride-Grafted PP, also known as MAgPP) effectively addresses this issue.
ENP is a modified polypropylene used as a coupling agent between polypropylene and glass fibers. By adding it in appropriate proportions, the bonding between polypropylene and glass fibers can be significantly improved. This improved bonding helps to further enhance the mechanical properties of the material, such as rigidity, ductility, surface gloss, and subsequent processability.
In the production of PP GF composites, adding 10% to 12% of ENP can increase tensile strength by 50%-100%, and elongation at break and impact strength by 10%-20%.
As an excellent coupling agent material, ENP provides an important solution for improving the performance of polymer materials. By incorporating ENP, we can overcome the bonding issues between polypropylene and glass fibers, thereby enhancing the overall performance and quality of the material.
