KUALA
LUMPUR, March 3 -- The Polyplastics Group is offering an improved
polybutylene terephthalate (PBT) grade, providing improved tracking resistance
for a range of high-voltage automotive components.
DURANEX (R) PBT CG7030 is a
30 per cent glass-filled grade which also delivers strong dimensional stability
and highly stable electrical resistance and dielectric breakdown properties,
according to a statement.
The automotive industry is
undergoing drastic change with electrification gaining traction due to worldwide
efforts to reduce the use of fossil fuels and cut emissions. As car makers move
increasingly to electric vehicles, demand for high-voltage components is
expected to increase.
Polyplastics
conducted extensive testing of both PA 66 and PBT in temperature environments
ranging from -40 C to 140 C for electric car applications such as batteries,
power control units and motors/generators.
Since the properties of PBT
grades experience little change even in hot, moist environments, Polyplastics
determined that they are more suitable than PA66 for use in high-voltage
applications.
These results suggest that
using PBT could produce less variation in electrical properties when
environments change.
DURANEX (R) PBT CG7030 also
exhibits highly superior dimensional stability. Polyplastics reports that both
moisture absorption and dimensional change rates for PBT grades are around
one-tenth of the values observed for PA66-GF33 per cent.
