Product Overview
STCE59801 is a thermoplastic flame-retardant TPE cable compound developed for electronic wires and in-vehicle high-voltage wires. It combines high-temperature performance, strong electrical insulation and good mechanical properties with a thermoplastic processing route that does not require irradiation.
For EV high-voltage projects, STCE59801 provides a distinct alternative to Opta's irradiation-crosslinked XLPO grades EPC9258-H and EPC9508. Selection should be based on the required cable standard, temperature class, electrical performance, environmental resistance and processing route-not on the high-voltage application alone.
Why Choose STCE59801?
1. Thermoplastic TPE Route
No post-extrusion E-beam irradiation is required, simplifying the processing route where thermoplastic TPE is preferred.
2. Strong Electrical Insulation
Typical volume resistivity is 2.5 × 10¹⁶ Ω·cm, supporting electrical-insulation-focused wire constructions.
3. High Mechanical Performance
Typical tensile strength is 15.8 MPa with 320% elongation at break.
4. Flame-Retardant Material Performance
The supplied technical data lists UL 94 V-0 at a 4.0 mm specimen thickness.
5. Heat & Low-Temperature Impact
No cracking is recorded in the 130°C heat-impact test or the -40°C low-temperature impact test.
6. Low Density
Typical density is 1.03 g/cm³, offering a comparatively lightweight thermoplastic material route.
Typical Applications
- In-vehicle EV high-voltage wire constructions
- Electronic wires requiring flame-retardant TPE
- High-temperature wire applications
- Thermoplastic high-voltage cable material route
- Customized TPE cable designs requiring color or formulation matching
Important Application Note
STCE59801 is positioned by the supplied catalogue for in-vehicle high-voltage wires, but the available STCE59801 data does not assign a specific ISO 6722 / ISO 19642 automotive temperature class. The finished cable and applicable OEM/automotive standard must therefore be confirmed project by project.

Processing Guidelines
- Use the supplied temperature profile as the starting point and adjust according to extrusion speed and finished-surface quality.
- STCE59801 is thermoplastic TPE; no electron-beam irradiation step is required after extrusion.
- Confirm screw, die, conductor construction and line speed on the actual production equipment.
- For automotive high-voltage projects, validate the complete cable against the applicable OEM and cable-standard requirements.
- Color and formulation matching can be discussed for qualified projects.
