Valox is a the trade name for a family of thermoplastic polyester polymers originally developed by General Electric. GE sold its plastics division to a Saudi company, SABIC, in 2007, so now this is a SABIC material.
The general properties associated with any of the VALOX polymers include good heat resistance, good solvent resistance and good toughness. The exact properties will vary by specific grade. They also have excellent surface appearance. (That means they mold well and come out of the mold cleanly so they look shiny and have no pits or surface porosity. There are grades available that have chopped glass fiber mixed in, making those grades similar in performance to FRN.
If I had to guess at the properties without consulting specific data sheets, I would guess that it is less expensive to process than Nylon, might be a tad tougher than Nylon but maybe less strong.
