Electrification
EV Busbar & Power Electronics Housing
High-voltage assemblies put electrical isolation, flame behavior, creepage geometry, thermal cycling, and dimensional stability into the same part. The polymer is only one layer of safety: conductor spacing, connector sealing, contamination, color control, and the complete assembly test plan determine whether the design is robust.

Component material package
A recommended grade per component, drawn from the Nexeo catalog. Recommendations are engineering assessments; a cited property links the choice to data we hold for that grade.
| Component | Recommended grade | Why |
|---|---|---|
Busbar carrier Positions and electrically isolates stamped conductors | Ryton R-4-200BL Polyphenylene Sulfide (PPS-GF40) | A glass-reinforced PPS candidate offers a high-temperature, dimensionally stable starting point around conductors and insert-molding operations. |
Electronics enclosure Protects control electronics and connector interfaces | Bayblend T65 XF Polycarbonate Blend (PC-ABS) | A PC-ABS blend is a practical enclosure candidate where impact, moldability, and surface quality matter more than direct high-temperature conductor support. |
Perimeter seal Maintains environmental sealing through thermal cycles | Santoprene 121-70W175 Thermoplastic Vulcanizate (TPV) | A TPV seal candidate supports molded sealing geometry and serviceability after compression-set and coolant-exposure validation. |

Validation & compliance path
- OEM high-voltage component specification and orange-color control
- Flammability rating at the production wall thickness
- IEC 60664 creepage and clearance principles where adopted by the program
Engineering watch-outs
- A generic flammability label is incomplete without thickness and color qualification.
- Metal inserts and glass-filled resin have different thermal expansion; cycle the production stack-up.
- Electrical tracking risk depends on contamination and creepage geometry, not resin family alone.
