EVA/PE MASTERBATCH DELTAPLAST HFFR cables
DELTAPLAST EVA/PE masterbatches from Delta Tecnic are specifically designed for the colouring of HFFR cables, used in applications where fire safety is a critical requirement.
HFFR cables are widely used in electrical infrastructure, buildings and industrial installations because they reduce the emission of toxic gases and smoke in case of fire. In these highly filled flame-retardant compounds, achieving proper colour dispersion can be challenging.
DELTAPLAST HFFR solutions enable the desired colour to be achieved at low dosage levels, while maintaining the material’s flame-retardant properties. Thanks to their optimized formulation, these masterbatches ensure stable processing, excellent dilution and reliable performance across different polyolefin formulations.

DELTAPLAST EVA/PE masterbatches are designed to work with highly filled HFFR compounds, providing efficient colouration without compromising cable performance.
Key features include:
- Efficient colouration at low dosage: High pigment concentration allows the desired colour to be achieved with reduced masterbatch levels, optimizing cost and process efficiency.
- Reduced impact on flame-retardant properties: DELTAPLAST solutions are formulated to minimize their influence on the fire performance of HFFR compounds.
- Optimal dilution in highly filled compounds: HFFR compounds typically contain high mineral filler content. DELTAPLAST is optimized to ensure good dispersion even under these conditions.
- Stable processing under demanding conditions: The masterbatch provides stable behaviour during extrusion, even in demanding industrial processes.
- Compatibility with different polyolefin formulations: Solutions are adapted to work with various PE- or EVA-based matrices used in HFFR cables.
Additionally, the range includes colour references based on RAL standards, with thermal stability up to 200–230°C, suitable for cable extrusion processes.
Applications
DELTAPLAST EVA/PE masterbatches are designed for cable applications where fire safety is essential.
Typical applications:
- Power generation and distribution: Cables used in electrical generation and distribution infrastructure.
- Building wire: Electrical wiring for buildings, public infrastructure and construction projects.
- Power and data cables: Energy and data transmission cables used in industrial and telecom installations.
In these applications, HFFR cables improve safety in case of fire by reducing smoke emission and corrosive gases.
Technical FAQs
What does HFFR mean in electrical cables?
HFFR stands for Halogen Free Flame Retardant. These cables are designed to reduce smoke and toxic gas emissions in case of fire.
Does the masterbatch affect flame-retardant properties?
DELTAPLAST solutions are formulated to minimize their impact on the fire performance of HFFR compounds.
Why are EVA- or PE-based masterbatches used?
Because these polymers are compatible with the matrices used in HFFR cable compounds.
What are the advantages of the micro bead format?
Small spherical pellets improve dosing, colour dispersion and overall product homogeneity.
