Although the Dutch para-aramid fiber was developed only a little later than DuPont's Kevlar, introduction of Twaron as a commercial product came much later than Kevlar due to financial problems at the AKZO c… The manufacturing process allows for variations in the chemical make up. It is used as an Asbestos substitute. This allows it to be more active chemically than UHMWPE (Dyneema®, Spectra®) It also means it can be bonded for example to epoxy, and it is wettable. High Rigidity Young's modulus (stiffness): 130-179 GPa compared to carbon Fiber 300 GPa and glass 81 GPa, low elongation to Break (does not stretch much). Twaron was not made from Dupont even though they are naturally similar products in that Twaron is made of synthetic fibers just like the Kevlar. Polyethylene fibers have taken the place of Kevlar when it comes to modern armor. Its use as a bow string has pretty much been eliminated because it tends to fail fairly quickly and catastrophically. Furthermore, aramid fiber is suitable for the manufacture for phone covers since it is nonconductive and does not interrupt signals.
