Product Overview

EPC9054 is a 105°C irradiation cross-linked low smoke zero halogen high flame-retardant cable compound developed for demanding wire and cable applications. It can be used to manufacture wires designed to meet 105°C Class A bunched flame test requirements.

Its role within the 105°C irradiation-crosslinked LSZH family is very specific: EPC9051 is the standard 105°C route, while EPC9054 is selected when higher flame-retardant performance and Class A bunched-flame capability become the key project requirement. A recommended irradiation dose of 10–12 MRad is used as the starting process window.

Why Choose EPC9054?

1. Class A Bunched Flame Application Route

Developed for wire constructions requiring demanding Class A bunched flame performance at the 105°C level.

2. High Flame Retardancy

A typical oxygen index of 38% supports EPC9054's high flame-retardant positioning.

3. 105°C Cross-Linked Cable Performance

Irradiation cross-linking provides the heat resistance and dimensional stability required for higher-temperature cable applications.

4. Low Smoke Zero Halogen

Combines flame-retardant performance with low-smoke and zero-halogen material characteristics.

5. Reliable Mechanical Balance

Typical tensile strength is 12.7 MPa with 200% elongation at break before aging.

6. Production-Oriented Processing

Extruded on conventional cable equipment before irradiation cross-linking, supporting practical industrial manufacturing.

Processing Guidelines

EPC9054 can be processed on conventional PVC/PE cable extrusion equipment before irradiation.
After extrusion, irradiation cross-linking is required. Recommended irradiation dose: 10–12 MRad.
Keep melt temperature below approximately 165°C and do not exceed 175°C during extrusion.
A low-compression-ratio screw and head are recommended; approximately 1:1 to 1:2 is a practical starting range.
Optimize extrusion temperature, line speed, cooling and irradiation dose according to conductor size, insulation/sheath thickness and actual equipment.
Cross-linking level and final flame performance should be confirmed through production trials and finished-wire testing.

Why Irradiation Cross-Linking Matters

Before irradiation, EPC9054 is extruded as a thermoplastic compound. Electron-beam irradiation creates a cross-linked polymer network, improving heat resistance and dimensional stability. For this reason, extrusion quality and irradiation dose must be treated as one integrated manufacturing process rather than as independent steps.

EPC9054 vs. EPC9051

Selection Point	EPC9054	EPC9051
Temperature Route	105°C	105°C
Primary Position	High flame-retardant / Class A bunched-flame route	Standard 105°C irradiation-crosslinked LSZH route
Main Selection Driver	Higher flame-retardant requirement	General 105°C LSZH requirement
Recommended Irradiation	10–12 MRad	10–12 MRad
Choose When	Class A bunched flame performance is required	Standard 105°C performance is the main requirement

EPC9054 vs. Higher-Temperature Grades

Grade	Core Route	Main Selection Driver
EPC9054	105°C high flame-retardant	Class A bunched flame requirement
EPC9251	125°C irradiation-crosslinked LSZH	Higher temperature requirement
EPC9501	150°C irradiation-crosslinked LSZH	High-temperature requirement

Important Selection Note

Do not describe EPC9054 simply as a 'higher grade' than EPC9051, EPC9251 or EPC9501. EPC9054 is differentiated mainly by its high flame-retardant / Class A bunched-flame application route at 105°C. Final compliance depends on the complete wire or cable construction, extrusion, irradiation conditions and finished-product testing.
