TOKYO, May 14, 2024 /PRNewswire/ -- Polyplastics Co.,
Ltd., a leading global supplier of engineering thermoplastics, has
announced the launch of a next-generation polyphenylene sulfide
(PPS) grade that boasts significantly improved thermal shock
resistance and can be easily recycled during post-consumer
recycling (PCR) without sorting. DURAFIDE (R) PPS 1140HS6, a 40%
glass-filled grade, meets the requirements for metal insert
molding, particularly busbars for electric vehicles
(xEVs).

DURAFIDE (R) PPS 1140HS6 can be easily collected without being
separated from other PPS components during recycling. Polyplastics
has employed a material design technique to ensure thermal shock
resistance by minimizing residual strain during molding and
homogenizing linear expansion to mitigate internal stress. As a
result, thermal shock resistance has been improved while retaining
mechanical and other essential properties.
DURAFIDE (R) PPS 1140HS6 eliminates molding imperfections and
enhances performance without the need for impact modifiers in xEV
busbar applications. Insert molded xEV components conduct
high-voltage currents in various electrical parts and their complex
shapes make them susceptible to cracking. They are usually made up
of a metal that conducts electric power and PPS resin that
functions as a coating for insulation. This cracking problem is
caused by repeated heating and cooling and subsequent rapid
temperature changes. This is a significant issue, leading to
insulation failure, particularly in the critical parts of xEVs that
conduct high-voltage currents.
The typical solution is to add impact modifiers to PPS. Still,
this approach has drawbacks, such as a reduction in material
strength and the tendency for gases and mold deposits to emerge
during molding. Additionally, materials containing impact modifiers
are incompatible with the growing trend of material recycling.
The newly developed DURAFIDE (R) PPS 1140HS6 resin offers better
flowability during injection molding than standard materials. This
makes it an ideal choice for molding both thin-wall and large
products.
