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:
These unfilled and glass-filled grades have potential
for use in electric cooling fans, relays, connectors, switches and fuser
applications in printers.
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.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
