Synthetic mica tape


Application: It can be directly wound on the conductor (IEC331), or it can be wound in the conductor jacket to form an excellent flame retardant layer (IEC-322, UL910). It is an ideal refractory material for making fire-resistant wires and cables. According to (IEC371 -3-8).


Quality: Delicately made by bonding synthetic mica paper to fiberglass with specially selected silicone resin, which contains synthetic mica


Single crystal: KMg3 (AlSi3O10) F2 (melting point 1375±5℃), only an excellent refractory material. The fire-resistant wire and cable made of it can keep the power supply line intact for more than 90 minutes under the condition of high temperature shock of 950-1000 ℃ and the rated voltage of 0.6/1KV is applied at the same time.


Meet the following standards: ICE-331, UL1581, UL1277, UL910, JISC2166, BS6387CWZ, GB12666, DIN4102Part12, JFDB Test nr 7etc
