SABIC Innovative Plastics' Valox ENH Resins

Three Valox ENH PBT resin grades, with differentglass reinforcement levels, utilize non-brominated and non-chlorinated FR technology.The resins meet the UL94 V0 standardat 0.8 mm. With a comparative tracking index (CTI) of 500 volts for Valox ENH4530 resin and a CTI of 600 volts for Valox ENH 3500 and Valox ENH 4560 resins, standard glass-filled brominated PBT istypically around 200 volts.
The newValox ENH resin grades are:

  • Valox ENH 3500 PBT resin, unfilled

  • Valox ENH 4530 PBT resin, 15 percent glass fiber reinforced

  • Valox ENH 4560 PBT resin, 30 percent glass fiber reinforced


These unfilled and glass-filled grades have potentialfor use in electric cooling fans, relays, connectors, switches and fuserapplications in printers.

Accordingto SABIC Innovative Plastics' Valox ENH resin grades can be enhanced by combining them with other SABIC Innovative Plastics PBT technologies,particularly Valox iQ resins. This iQ technology is referred to as "upcycledtechnology" because it incorporates high levels of post-consumer polyethyleneterephthalate (PET) bottles into PBT resin through a proprietarychemical process. Upcycling not only diverts waste from landfills but alsoreduces carbon dioxide (CO2) emissions and energy usage whenproducing PBT resin. Valox iQ NH 4550 is made from upcycled post consumer PET.
