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.
