North Korea Calcined Mica Tape
Calcined mica tape is a strip- or roll-shaped insulating and fire‑resistant material made by using calcined muscovite paper as the base material, glass fiber cloth as the reinforcing material, and organic silicone resin as the binder. It can replace double-layer winding with single-layer winding to meet cable fire‑resistance requirements, making it particularly well suited for applications involving ultra‑small cross‑section fire‑resistant cables.
Features:
▪ High and stable temperature resistance
▪ Good insulation performance at high temperatures
▪ Excellent softness
Temperature resistance:
▪ 950–1000°C
