EV parts made with Syensqo’s PPS wins SPE award
Syensqo, a global supplier of advanced performance materials and chemical solutions, has won the Safety category at the 2024 SPE Innovation Awards North America, with the upper clips of advanced busbar cable support bracket made from Syensqo’s Ryton PPS.
Busbar cable support bracket with upper clips made of Ryton R-4-220 BL.
The advanced busbar cable support bracket is utilized in the 2025 Cadillac CELESTIQ, a flagship EV in General Motors’ lineup.
The bracket, injection molded by Grand Traverse Plastics, is engineered to prevent thermal runaway and high-voltage arcing by minimizing cable motion through the use of high-performance, V0-rated PPS and PBT materials.
The upper clips, made from Syensqo’s Ryton R-4-220 BL PPS, provide a rigid and secure connection to the busbars, meeting stringent retention requirements while also optimizing assembly efficiency.
Unlike metal brackets, this design delivers exceptional durability and thermal stability, ensuring the 15kg busbar remains isolated without damaging its insulation. The use of specialty plastic materials also allows for a reliable and predictable grounding pathway, enhancing overall safety.
The innovative snap-fit design delivers over 240N of axial retention force with a single fastener per location, reducing the need for more than 10 fasteners per RESS. The installation requires just 45N of insertion force, making assembly ergonomically safe and significantly reducing operator fatigue.
This efficiency not only improves production speed but also decreases scrap costs by up to 99%, reflecting significant advancements in sustainability and cost-effectiveness.
