Product Overview
EPC6801 is a flexible thermoplastic low-smoke zero-halogen cable compound developed for cable constructions that require a softer hand feel and greater flexibility than conventional rigid LSZH formulations. It can be considered for flexible wire and cable applications and for projects seeking a halogen-free alternative to soft PVC.
The grade combines Shore A 89 hardness with 300% elongation at break, while maintaining flame-retardant and low-smoke halogen-free characteristics. Because EPC6801 is thermoplastic, it can be extruded directly without a subsequent irradiation cross-linking step.
Its role within the EPC6xxx family is clear: EPC6907 is the general-purpose LSZH sheathing grade, EPC6802 is the low-temperature flexible grade, while EPC6801 is the softer elastomeric option where cable flexibility and hand feel are key selection factors.
Key Features
- Soft & Flexible Cable Material
Shore A 89 hardness and 300% elongation provide a softer, more flexible profile for cable constructions requiring improved hand feel.
- Halogen-Free Formulation
Measured halogen content is 0 ppm in the supplied product data, supporting halogen-free cable-material positioning.
- Low-Smoke Performance
Smoke-density data are available for both flaming and non-flaming test conditions.
- Flame-Retardant Performance
An oxygen index of 30% provides a useful flame-retardant baseline for flexible LSZH cable applications.
- Thermoplastic Processing
No irradiation step is required, simplifying processing compared with cross-linked XLPO products.
- Alternative to Soft PVC
Suitable for projects seeking flexible halogen-free cable compounds as an alternative to conventional soft PVC.
- Thermal & Mechanical Balance
Provides 9.1 MPa tensile strength, 300% elongation, heat-aging retention and thermal-shock performance.
Typical Applications
- Flexible electrical wires and cables
- Flexible cable insulation
- Flexible cable sheathing / jacketing
- Internal equipment wiring requiring a softer cable feel
- Low-smoke zero-halogen flexible cable constructions
- Projects replacing soft PVC with a halogen-free thermoplastic compound
- General flexible wire applications where -25°C impact performance is sufficient

Primary Positioning |
Key Difference |
Choose When |
|
EPC6907 |
LSZH sheathing |
Balanced processability, flame retardancy and flexibility |
You need a general cable sheath; also applicable to communication / marine projects when the construction requirements match |
|
EPC6901 |
LSZH insulation |
Higher insulation focus and low water absorption |
Electrical insulation is the main function |
|
EPC6909 |
Oxygen-barrier compound |
High char formation / low heat-release positioning |
A cable oxygen-barrier layer is required |
|
EPC6902 |
Injection-molding compound |
Very high melt flow |
Connectors, plugs or molded cable parts are required |
|
EPC6801 |
Flexible elastomeric LSZH |
Soft feel, Shore A 89, 300% elongation |
Flexibility and soft-PVC replacement are priorities |
|
EPC6802 |

- EPC6801 can be produced on conventional PVC/PE cable extrusion equipment.
- Recommended melt temperature: 165°C; do not exceed 175°C.
- A low-compression screw and head are recommended, with a compression ratio of approximately 1:1–1:2.
- Actual settings should be optimized according to cable structure, extrusion speed, wall thickness and surface-quality requirements.
Storage & Drying
When the original sealed packaging is intact, special drying is normally not required. If the material has been stored for an extended period in a humid environment, dry at approximately 70°C for 4 hours in a dehumidifying dryer before processing.
