Web14 de abr. de 2024 · Photo Credit: Teijin. Teijin Ltd. (Tokyo, Japan) reported on April 12 that it has qualified its carbon fiber and polyetheretherketone (PEEK)-based materials Tenax thermoplastic woven fabric (TPWF) and Tenax thermoplastic consolidated laminate (TPCL) with NCAMP (National Center for Advanced Materials Performance, Wichita, Kan., U.S.). Most typical ion-exchange resins are based on crosslinked polystyrene. The actual ion-exchanging sites are introduced after polymerisation. Additionally, in the case of polystyrene, crosslinking is introduced by copolymerisation of styrene and a few percent of divinylbenzene. Crosslinking decreases ion-exchange capacity of the resin and prolongs the time needed to accomplish the ion-exchange processes but improves the robustness of the resin. Particle size also influences …
