Three Valox ENH PBT resin grades, with different
glass reinforcement levels, utilize non-brominated and non-chlorinated FR technology.
The resins meet the UL94 V0 standard
at 0.8 mm. With a comparative tracking index (CTI) of 500 volts for Valox ENH
4530 resin and a CTI of 600 volts for Valox ENH 3500 and Valox ENH 4560 resins, standard glass-filled brominated PBT is
typically around 200 volts.
The new
Valox 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 potential for use in electric cooling fans, relays, connectors, switches and fuser applications in printers.
According to 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 "upcycled technology" because it incorporates high levels of post-consumer polyethylene terephthalate (PET) bottles into PBT resin through a proprietary chemical process. Upcycling not only diverts waste from landfills but also reduces carbon dioxide (CO2) emissions and energy usage when producing PBT resin. Valox iQ NH 4550 is made from upcycled post consumer PET.
