Mica Tape in Spool

Mica tape for fire-resistant cable is made of high quality phlogopite mica paper, synthetic mica paper or calcined mica paper as the base material, with alkali-free glass fibre cloth or polymer film (e.g. PE) as the reinforcing material on one or both sides. The final product is obtained by bonding with silicone resin, followed by high temperature baking, drying and slitting. The mica tape is mainly used between the core and the sheath of fire-resistant cables to perform the function of fire-resistant insulation.

The mica tape length per roll is 500m-1000m in general. When one roll of mica tape is used up, replacing new mica roll takes much time. In order to save time, the tray is developed thereby. The longest length of tape in one tray can be up to 50000m(The tray diameter is 400mm and height is 400mm).
