EPDM/EPR Rubber Masterbatch for Energy Cables – DELTAPLAST
DELTAPLAST EPDM/EPR Rubber Masterbatches from Delta Tecnic are designed for energy cable applications based on rubber compounds, where flexibility, mechanical resistance and reliable performance are required under demanding conditions.
EPDM and EPR compounds are widely used in energy cables due to their excellent thermal resistance, dielectric properties and ability to withstand harsh industrial environments.
In these materials, achieving homogeneous pigment dispersion can be challenging. DELTAPLAST solutions for EPDM and EPR are therefore formulated to ensure excellent colour dispersion, stable processing and reliable performance throughout the cable’s service life.

DELTAPLAST masterbatches for EPDM/EPR compounds are specifically developed to meet the technical requirements of rubber-based energy cables.
Key features include:
- Solutions tailored for EPDM and EPR compounds: Masterbatches are designed for optimal integration into rubber matrices used in energy cable applications.
- Careful pigment selection: Pigments are selected to ensure colour stability without affecting the electrical or mechanical properties of the material.
- Excellent dispersion in rubber matrices: Formulations enable homogeneous pigment distribution, ensuring uniform colour in cable insulation or jacketing.
- Reliable processing performance: Masterbatches provide stable behaviour during mixing and extrusion of rubber compounds.
- Suitable for demanding energy applications: DELTAPLAST solutions are designed for applications where cable reliability is critical.
According to the technical bulletin, these masterbatches feature a low melting point (approx. 78–81°C), facilitating their incorporation into EPDM/EPR rubber compounds.
This low melting point, combined with excellent dispersion and dilution, ensures high colour consistency during cable production.
The range includes various colour references based on RAL standards, with the possibility to develop custom colours according to customer specifications.
Applications
