Calcined Mica Tape
Calcined mica tape for halogen-free fire-resistant cables, 900 °C to 950 °C.
Product Details
Calcined Mica Tape
Calcined mica tape is built on calcined phlogopite mica paper, reinforced with fiberglass cloth and bonded with a high-temperature resistant adhesive. It keeps a good balance between rigidity and flexibility, so the tape holds a high tensile strength while still wrapping tightly around the conductor.
Yitian multi-layer three-in-one calcined phlogopite mica tape uses high-quality calcined phlogopite mica as the base material, giving good high-temperature and electrical performance together with excellent abrasion and chemical resistance. Modified and reinforced grades are available to match special processing and end-customer requirements.
What this grade gives you
- Calcined phlogopite mica paper base
- Balanced rigidity and flexibility
- High tensile strength with tight wrapping
- High-temperature and electrical performance
- Abrasion and chemical resistance
- Modified and reinforced grades available
