Phenol Aldehyde PF
INTRODUCTION TO PHENOL ALDEHYDE
Phenol aldehyde, sometimes also known as novoloid, is made by acid-catalyzed cross-linking of melt-spun novolac resin to form a fully cross-linked, three-dimensional, amorphous "network" polymer structure similar to that of thermo-setting phenolic resins. Chemically, the fibers contain approximately 76% carbon, 18% oxygen, and 6% hydrogen.
Because of their basic chemical structure, Phenol aldehyde is infusible (non-melting) and insoluble, and possess physical and chemical properties that clearly distinguish them from all other man-made and natural fibers.
