Product Overview
EPC9901 is a 90°C Irradiation Cross-Linked LSZH Cable Compound developed for low smoke zero halogen wire and cable insulation. After extrusion, electron-beam irradiation completes the cross-linking process. The material is designed for GB/T 32129-2015 WDZ-YJ-J90 cable applications.
This E-beam cross-linkable HFFR cable compound combines flame retardancy, heat resistance and reliable mechanical properties after cross-linking. It can also be described as an irradiation crosslinked LSZH compound, electron beam crosslinked cable material or irradiation XLPO cable compound. The recommended irradiation dose is 10–12 MRad.

EPC9901 can be extruded on conventional PVC/PE cable extrusion equipment. Electron-beam irradiation is required after extrusion to complete the cross-linking process.
Keep the melt temperature below 165°C, with 175°C as the maximum processing limit.
A low-compression screw and head are recommended, with a compression ratio of approximately 1:1–1:2.

FAQ
1. What is EPC9901?
EPC9901 is a 90°C Irradiation Cross-Linked LSZH Cable Compound for low smoke zero halogen wire and cable insulation.
2. Is EPC9901 an HFFR cable compound?
Yes. EPC9901 is a halogen-free flame-retardant HFFR cable insulation compound designed for irradiation cross-linking.
3. What does WDZ-YJ-J90 mean for EPC9901?
EPC9901 is designed for GB/T 32129-2015 WDZ-YJ-J90 cable applications with a 90°C temperature rating.
4. How is EPC9901 cross-linked?
The extruded cable material is cross-linked by electron-beam irradiation.
5. What irradiation dose is recommended?
The recommended irradiation dose is 10–12 MRad.
6. Is EPC9901 a cross-linked polyolefin compound?
Yes. EPC9901 can be described as an irradiation XLPO cable compound or irradiation crosslinked halogen-free polyolefin cable material.
7. How does EPC9901 perform after heat aging?
After aging at 120°C for 168 hours, EPC9901 maintains a tensile strength of 15.1 MPa and an elongation at break of 203%.
8. How is irradiation cross-linked LSZH different from silane XLPE?
The main difference is the cross-linking route: EPC9901 uses electron-beam irradiation, while silane XLPE is typically cross-linked through silane and moisture curing.
9. Can customized colors and formulations be supplied?
Yes. Color matching and formulation customization can be provided according to cable performance requirements.
10. Can free samples be provided?
Yes. Samples can be provided for extrusion, irradiation and cable performance evaluation.
