Mica Tape for Cable

Description

SIDA Mica Tape represents the gold standard in fire-resistant cable insulation, designed to maintain circuit integrity during extreme thermal events. Our advanced manufacturing process bonds naturally exfoliated mica paper to reinforced backing materials, creating a flexible yet robust insulation solution that outperforms conventional materials in high-stress environments.

Core Composition:

Mica Paper Layer: Premium phlogopite or muscovite mica with exceptional thermal and electrical properties
Reinforcing Backing: Alkali-free glass fiber cloth or polyethylene film for mechanical strength
Binder System: High-temperature silicone resin ensuring stability from -50°C to +800°C
Halogen-Free: Non-toxic, chemically neutral composition with zero halogen emission

Key Performance Characteristics: The tape maintains dielectric strength exceeding 1.5 kV per layer at temperatures up to 380°C, with graded performance continuing beyond 1000°C. Unlike polymer-based insulations that melt or combust, SIDA mica tape forms a ceramic-like barrier that prevents conductor contact and maintains functional integrity during fire exposure exceeding 3 hours at 900°C

Superior Fire Safety: Our mica tape enables cables to pass the most stringent international fire tests including BS 6387 Categories C, W, and Z; IEC 60331 (750°C for 3 hours); and Belgian standard NB 30.004 (900°C for 3 hours with mechanical impact)

. The fibreglass backing ensures non-combustibility with zero thermal input during flame propagation tests.

Frequently Asked Questions

Q1: What is the minimum overlap required for fire-resistant cables?
A: For optimal fire resistance, a minimum 50% overlap with two layers is required. This configuration enables cables to pass IEC 60331 and BS 6387 testing protocols .

Q2: What is the difference between phlogopite and muscovite mica tape?
A: Phlogopite offers superior heat resistance (up to 840°C) and is ideal for fire-resistant cables. Muscovite provides better electrical insulation properties and is preferred for high-voltage motor applications. Synthetic mica exceeds 1000°C for critical aerospace applications

Q3: How long can mica tape maintain circuit integrity during a fire?
A: Properly applied SIDA mica tape maintains circuit integrity for 3+ hours at temperatures up to 950°C, meeting BS 6387 Category Z and passing the demanding NB 30.004 test (900°C for 3 hours with mechanical impact)

Q4: Is mica tape suitable for low-smoke, halogen-free (LSZH) applications?
A: Yes. Our mica tape is completely halogen-free, non-toxic, and produces minimal smoke emission, meeting IEC 60754-1/-2 and BS EN 61034-2 standards for LSZH applications

Q5: What width tolerances can you achieve for precision applications?
A: We offer precision slitting down to 3mm width with ±0.1mm tolerance, suitable for 22 AWG wires and larger. Standard widths from 5mm to 1000mm are available from stock

Q6: How should mica tape be stored, and what is its shelf life?
A: Store in original packaging at ambient temperature (15-30°C) with <60% humidity. Shelf life is 3 years; beyond this, flexibility may decrease but electrical and thermal properties remain intact

Q7: Can mica tape withstand chemical exposure?
A: Yes. It resists water, acids, bases, mineral oils, and most solvents. Properties remain stable up to 10⁹ Rad radiation exposure. Avoid concentrated sulfuric acid
