105°C UL VW-1 XLPO Wire Compound

EPC9053 is developed for 105°C electronic and equipment wire constructions where vertical flame performance is a key design requirement. Its positioning centers on a zero-halogen XLPO route for finished wires targeting VW-1 performance.

The defining value of this 105°C UL VW-1 XLPO Wire Compound is the combination of a 105°C temperature class, zero-halogen formulation and VW-1-oriented flame design. After extrusion, the material is cross-linked by electron-beam irradiation; the recommended starting dose is 10-12 MRad.

• 105°C UL wire material platform for electronic and equipment wiring.
• VW-1-oriented formulation for finished-wire vertical flame testing.
• Zero-halogen XLPO route with typical halogen content of 0 ppm.
• High typical oxygen index of 45% supporting the flame-retardant formulation.
• 11.3 MPa tensile strength and 215% elongation for balanced insulation performance.
• Heat-aging retention measured after 136°C × 168 h.
• Electrical insulation supported by typical volume resistivity of 2 × 10¹² Ω·m.
• Electron-beam crosslinking after extrusion; recommended dose 10-12 MRad.

• VW-1 as the primary design target: EPC9053 is built around 105°C finished-wire vertical flame qualification rather than a generic UL compound claim.
• Zero-halogen route at 105°C: a distinct choice when VW-1 is required without moving to a low-halogen formulation.
• Electronic-wire fit: suitable for hook-up, appliance and internal equipment wiring where wall thickness and flame behavior must be balanced.
• Process-to-test support: extrusion quality, insulation thickness and irradiation conditions can be optimized together during VW-1 trials.

• Electronic hook-up wire
• Internal appliance wiring
• Electrical and electronic equipment wire
• Control and connection wire inside equipment
• Other 105°C cross-linked UL wire constructions targeting VW-1 performance

VW-1 is evaluated on the completed wire rather than on the raw compound alone. For EPC9053 projects, conductor size, insulation wall thickness, extrusion quality, irradiation dose and the final wire construction should therefore be evaluated as one system. This page keeps the focus on that 105°C VW-1 use case instead of repeating the broader UL XLPO family selection content.

1. Confirm the 105°C wire design, conductor size, insulation thickness and VW-1 target.

2. Extrude EPC9053 with stable wall thickness, surface quality and conductor centering.

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

4. Check mechanical properties and heat-aging retention after irradiation.

5. Test VW-1 on the finished wire and optimize wall thickness / irradiation conditions if required.

6. Freeze production parameters only after the complete wire construction has passed qualification.

For EPC9053 projects, technical support can focus on conductor size, insulation wall thickness, extrusion quality, irradiation dose and finished-wire flame testing. Samples can be supplied for extrusion and VW-1 qualification trials.
