ETFE Masterbatch for T5/T6 Automotive Cables – DELTAPLAST
DELTAPLAST ETFE Masterbatches from Delta Tecnic are specifically developed for high-temperature automotive and specialty cable applications where thermal resistance, colour stability and mechanical performance are critical.
ETFE (Ethylene Tetrafluoroethylene) is widely used in automotive cable insulation systems exposed to extreme temperatures and radiation heat thanks to its excellent thermal resistance, dielectric properties and long-term durability.
In these demanding applications, the masterbatch must provide stable colour performance without affecting the processing behaviour or mechanical integrity of the fluoropolymer compound.
DELTAPLAST ETFE solutions are manufactured using ETFE resin and are engineered to ensure excellent dilution, perfect dispersion and colour regularity during high-temperature extrusion processes.

The DELTAPLAST ETFE Masterbatch range has been developed for automotive cable manufacturers requiring reliable performance in T5 and T6 thermal class applications according to ISO 6722.
Key technical benefits include:
- High-temperature resistance: According to the Product Bulletin, DELTAPLAST ETFE masterbatches are designed for cable systems operating within:
- T5: -40 °C to +175 °C
- T6: -40 °C to +200 °C
for continuous service conditions over 3,000 hours according to ISO 6722.
- Excellent mechanical properties: The formulations are designed to maintain the mechanical integrity and flexibility of ETFE cable compounds even under extreme thermal conditions.
- Perfect dispersion and excellent dilution: Delta Tecnic’s fluoropolymer dispersion technology ensures homogeneous pigment incorporation, helping improve colour consistency and reduce defects during extrusion.
- Colour regularity in high-temperature extrusion: The colour range has been specifically developed to operate under ETFE extrusion temperatures while maintaining stable colour performance and process consistency.
Low-flow and high-flow ETFE masterbatch ranges: Delta Tecnic offers two different ETFE masterbatch technologies:- Low-flow range
- High-flow range
allowing manufacturers to optimise performance depending on extrusion conditions and cable requirements.
- Extreme thermal stability during processing: The Product Bulletin indicates heat resistance above 300 °C for all colour references, making these formulations suitable for demanding ETFE processing conditions.
- High lightfastness performance: Most colour references achieve lightfastness values between 7 and 8, ensuring long-term colour stability in demanding applications.
