Product Overview
EPC6907 is a CPR Eca LSZH Communication Cable Compound developed for communication and telecom cable outer jackets. It combines thermoplastic processing, low-smoke zero-halogen fire-safety positioning, crack resistance and low heat shrinkage in one cable-jacket material.
For communication cable projects, the CPR Eca Communication Cable LSZH Sheathing Compound is positioned for cable constructions targeting CPR Eca flame performance. The final CPR class must be verified on the complete finished cable because CPR classification applies to the cable system rather than to the raw compound alone.
Why Choose EPC6907 for Communication Cables?
1. CPR Eca Communication-Cable Route
The Opta communication-cable portfolio positions EPC6907 for communication / telecom cable constructions targeting CPR Eca flame performance.
2. Low Smoke & Zero Halogen
Typical halogen content is 0 ppm, supporting LSZH / HFFR communication-cable jacket designs.
3. Good Crack Resistance
Designed to help maintain outer-jacket integrity during extrusion, installation and service.
4. Low Heat Shrinkage
Supports dimensional stability of communication and telecom cable jackets after processing.
5. Thermoplastic Processing
Can be processed by thermoplastic extrusion without an irradiation step, simplifying cable production.
6. Balanced Mechanical & Flame Performance
Typical 12.6 MPa tensile strength, 220% elongation and 35% oxygen index provide a balanced material profile for compatible communication-cable constructions.
Typical Communication Cable Applications
- Communication cable outer jackets
- Telecom cable sheathing
- Data and signal cable outer jackets requiring LSZH / HFFR performance
- Indoor communication cable constructions targeting CPR Eca
- Low-smoke zero-halogen telecom cable jackets
- Other communication cable constructions requiring thermoplastic LSZH sheathing
- Customized communication cable jacket designs subject to finished-cable validation
Important CPR Application Note
CPR Eca is a performance classification of the finished cable. EPC6907 should therefore be described as a communication-cable sheathing compound for cable constructions targeting CPR Eca, not as a raw material with standalone CPR Eca certification. Final classification depends on the complete cable design and test result.

Processing Guidelines for Communication Cable Sheathing
- Use the supplied temperature profile as the starting point and optimize according to extrusion speed, jacket thickness and surface quality.
- Conventional PVC/PE cable extrusion equipment can be used.
- No additional drying is normally required when original packaging remains intact; after prolonged humid storage, approximately 70°C × 4 h drying can be considered.
- For CPR projects, evaluate sheath thickness, cable OD, internal cable construction and finished-cable flame performance rather than relying on raw-material data alone.
- Color matching, formulation matching and extrusion support can be discussed for qualified communication-cable projects.
