A novel route to enhance the ductile performance of MF resins by addition of polyamide amine (PA)

Abstract

Addition of small proportions of polyamide amine to MF resins for the purpose of resin impregnation yields a considerable improvement in both paper toughness and tensile fracture strength. The fracture strain of impregnated paper with modified resin was enhanced by more than 100% (1.08%) as compared to comparable impregnation with neat MF resin (0.49%) without sacrificing the tensile strength.
