Application of mica tape in insulation engineering

2020 04/21

Mica tape is a kind of high-efficiency fireproof insulation tape, which has the advantages of low price and high insulation performance
For example, the fire-resistant mica tape dedicated to cable engineering is a high-performance mica insulation product with excellent high-temperature resistance and combustion resistance. The powder mica tape has good softness in normal condition and is suitable for the main fire-resistant insulation layer in various fire-resistant cables. In the event of fire burning, there is basically no volatilization of harmful smoke, so this product is not only effective for cables, but also very safe.
Synthetic refractory mica tape is an enhanced version of general fire resistant mica tape, with high temperature resistance and absolute flame retardant effect.
Its production process is to synthesize mica to replace hydroxyl with fluoride ion, and to synthesize artificial mica with large size and complete crystal form under normal pressure conditions. Synthetic mica tape is made of mica paper made from synthetic mica, and is made by bonding glass cloth to one side or both sides with an adhesive. The glass cloth is affixed to one side of the mica paper called "single sided tape," and both sides are called "double sided tapes." In the manufacturing process, several layers of structure are glued together, then dried in a furnace, then wound up, and then cut into different sizes of tape.
