Four engineered grades for every fire-safety and high-voltage application. From BS 6387-certified fire-survival cable tapes, to ultra-pure synthetic tapes for 110 kV systems, to premium PI "gold finger" reinforced tapes for HV motor windings — SZX New Materials supplies every mica tape grade the modern cable and motor engineer needs.
Every grade below is manufactured in-house, tested per batch, and packed for global export. Click through for full specifications and TDS.
The factory-direct overview of our entire mica tape lineup. Four production lines, 4,000+ tons annual capacity, every grade from phlogopite fire-cable tapes to synthetic ultra-pure and PI polyimide premium tapes. Discover our full manufacturing process from raw material to finished export roll — plus the complete list of industry standards and certifications we comply with.
The industry-standard fire-resistant cable tape. Phlogopite mica core + double-sided glass cloth + silicone resin. BS 6387, UL94 V0, RoHS, ELV compliant — for life-safety circuits in buildings, tunnels, subways, and data centers.
Lab-grown fluorophlogopite — zero iron oxide, zero quartz impurities. Rated for HV systems up to 110 kV. Available in Z-series (glass cloth) and N-series (high-mica). For EV motors, aerospace, MRI machines, and particle accelerators.
Phlogopite mica + polyimide film (the "gold finger" material). Combines high-voltage dielectric integrity with exceptional flexibility, radiation resistance, and mechanical durability. Standard for HV motor windings, aerospace wiring, and medical equipment.
