Polypropylene (PP) is a non-polar polymer, which results in poor surface adhesion with glass fibers, leading to ineffective manifestation of its properties. However, ENP (Maleic Anhydride-Grafted PP, also known as MAgPP) produced by AAP Corp. can effectively address this issue.

ENP is a modified polypropylene (modified PP) used as a bridging agent between polypropylene and glass fibers. By adding ENP in the appropriate proportions, the adhesion between polypropylene and glass fibers can be significantly improved. This enhanced bonding helps further enhance the mechanical properties of the material, such as rigidity, elongation, surface gloss, and processability.
 

By adding approximately 10% of ENP, not only can the tensile strength be increased by 50%, but the tensile elongation at break rate and IZOD can also be effectively improved by 10%-20%. Additionally, due to its high melting index, the surface glossiness and smoothness of PP+GF materials can be significantly improved, helping to mitigate the issue of floating fiber.
 

ENP serves as an excellent bridging agent material, providing an important solution for enhancing the performance of polymer materials. By incorporating ENP, we can overcome the adhesion issues between polypropylene and glass fibers, thereby elevating the overall performance and quality of the materials.
