Mica and Shielding for Railway Cables
Halogen-free materials for circuit integrity per EN 45545, IEC 60331. Stock in Barcelona, in-house taping service at 80 km/day.
Mica Tapes for Circuit Integrity
Mica tapes ensure that the cable retains its function during a fire. Calcined mica on alkali-free glass-fibre fabric, with a high-resistance silicone resin binder. Halogen-free and free of toxic gases.
Muscovite Mica FR80M28
Standard grade for IEC 60331, EN 50200. Maximum dielectric strength. Halogen-free and free of toxic gases.

Phlogopite Mica (FR-P series)
Higher thermal resistance up to 1000°C. Greater flexibility for small cross-sections and high-speed taping. Halogen-free.

| FR120P28 | 0.120 ±0.02 mm | 125 ±5 g/m² | ≥1.2 kV/capa |
| FR160P28 | 0.150 ±0.02 mm | 160 ±5 g/m² | ≥1.5 kV/capa |
EMI Shielding
AL/PET laminates for signalling cables
Railway signalling and communication systems require shielding against electromagnetic interference. The AL/PET laminate provides an effective shield in data, signal and instrumentation cables. Available with a lubricated option for high-speed helical taping.
Electrical Insulation and Separation
PET film for layer insulation
PET film acts as a dielectric insulator between layers and as a separator between cable components. High dielectric strength, resistance to water and chemical vapours, dimensional stability. Multiple thicknesses and finishes available.
Flame-Retardant Tape
Alternative to mica for CPR compliance
Where full circuit integrity is not required but CPR standards on smoke and flame propagation must be met, the flame-retardant tape offers an alternative to mica. Non-woven polyester base with retardant elements, halogen-free.
