150°C UL FT-2 XLPO Wire Compound

EPC9502 is developed for high-temperature wire insulation projects requiring a 150°C XLPO platform, zero-halogen formulation and FT-2 finished-wire flame positioning. Its main differentiation within the UL-oriented XLPO family is thermal endurance rather than a change in basic cable-layer function.

The defining qualification point of this 150°C UL FT-2 XLPO Wire Compound is the 180°C × 168 h aging condition. Typical tensile strength is 15.2 MPa and elongation at break is 350% after irradiation; after aging, typical values are 17.9 MPa and 302%. This makes EPC9502 the dedicated high-temperature option for projects that need to move beyond the 125°C FT-2 route.

• 150°C irradiation-crosslinked XLPO insulation platform.
• 180°C × 168 h heat-aging condition as the key thermal qualification point.
• 15.2 MPa typical tensile strength after irradiation.
• 350% typical elongation after irradiation and 302% after heat aging.
• Low-temperature impact at -25°C: Pass; thermal shock at 150°C: Pass.

• 150°C thermal class is the core reason to select EPC9502; it is intended for projects that exceed the 125°C XLPO range.
• 180°C × 168 h aging provides a clear high-temperature validation point and separates EPC9502 from lower-temperature FT-2 grades.
• Zero-halogen positioning supports high-temperature wire designs where halogen-free material selection is required.
• 350% elongation after irradiation gives EPC9502 useful mechanical flexibility despite its high-temperature positioning.

• 150°C electronic hook-up wire
• High-temperature appliance wiring
• Electrical equipment internal wiring
• Motor lead and equipment connection wire
• Industrial and other 150°C zero-halogen wire constructions targeting FT-2 performance

For EPC9502, the most useful project discussion is thermal endurance. The listed 180°C × 168 h aging condition, together with retained tensile strength and elongation, gives wire manufacturers a specific basis for evaluating a 150°C construction. FT-2 remains a finished-wire test, so conductor size, insulation thickness, irradiation conditions and the complete wire design must still be validated together.

1. Check that the finished wire actually needs the 150°C material option.

2. Before extruding, set the conductor size, insulation thickness, and FT‑2 goal.

3. Run EPC9502 with steady wall thickness, centered cores, and smooth surfaces.

4. Crosslink by electron beam, starting with a dose around 10–12 MRad.

5. After that, test mechanicals, hot‑set, and 180°C/168h aging retention.

6. Do FT‑2 and final qualification; then freeze your production settings.

For EPC9502 evaluation, please provide the target 150°C wire standard, conductor size, insulation thickness, FT-2 requirement, extrusion-line information and irradiation conditions. Technical support can focus on high-temperature wire design, heat-aging retention, irradiation and finished-wire validation.
