125°C UL FT-2 XLPO Wire Compound

EPC9252 is developed for 125°C wire insulation where zero-halogen construction, flexibility and FT-2 finished-wire flame performance are required. Its typical 345% elongation gives this grade a distinctly flexible mechanical profile within the high-temperature UL-oriented XLPO family.

The key value of this 125°C UL FT-2 XLPO Wire Compound is not simply a higher temperature rating. EPC9252 combines a 125°C application platform, zero-halogen formulation, FT-2-oriented finished-wire performance and strong elongation retention after 158°C × 168 h heat aging, making it suitable for electronic, electrical equipment and motor-lead wire projects.

• 125°C XLPO insulation platform for electronic and electrical wire.
• FT-2-oriented formulation for finished-wire horizontal flame testing.
• Zero-halogen route with typical halogen content of 0 ppm.
• High typical elongation of 345% for flexible insulation constructions.
• 15.1 MPa tensile strength with 300% elongation retained after heat aging.
• 158°C × 168 h aging condition supporting the 125°C material positioning.
• Electrical insulation supported by typical volume resistivity of 2.5 × 10¹² Ω·m.
• Electron-beam crosslinking after extrusion; recommended dose 10-12 MRad.

• FT-2 as the page's primary flame route: EPC9252 is positioned for finished-wire constructions targeting FT-2 rather than VW-1.
• 125°C zero-halogen combination: suitable when the project requires a higher thermal class than 105°C while retaining a halogen-free formulation.
• High elongation as a mechanical differentiator: 345% typical elongation supports flexible wire insulation and motor-lead applications.
• Aging retention for 125°C projects: after 158°C × 168 h aging, typical elongation remains 300%, giving customers a clear qualification point beyond generic LSZH claims.

• Electronic wire requiring 125°C insulation
• Electrical equipment wiring
• Motor lead wire
• Internal appliance and equipment wire
• Control, connection and other 125°C zero-halogen wire constructions targeting FT-2 performance

FT-2 is evaluated on the completed wire rather than on the raw compound alone. For EPC9252 projects, insulation thickness, conductor size, extrusion stability and irradiation conditions should be developed around the finished-wire FT-2 target. The material's high elongation and aged-property retention provide useful room for wire-design optimization, but final compliance still depends on the complete construction.

1. Confirm the 125°C wire design, conductor size, insulation thickness and FT-2 target.

2. Extrude EPC9252 with stable wall thickness, conductor centering and surface quality.

3. Cross-link the insulation by electron-beam irradiation; use 10-12 MRad as the recommended starting range.

4. Verify tensile, elongation and 158°C × 168 h aging retention after irradiation.

5. Test FT-2 on the finished wire and adjust insulation thickness / irradiation conditions where required.

6. Freeze production parameters only after the complete wire construction passes project qualification.

For EPC9252 projects, technical support can focus on 125°C wire design, insulation flexibility, wall thickness, extrusion stability, irradiation dose and finished-wire FT-2 testing. Please send conductor size, insulation thickness, target wire standard and test requirement for sample evaluation.
