With the development of wire and cable industry, the requirements and improvement of phlogopite mica tape in wire and cable is more and more.
phlogopite mica tape has good fire resistance, acid and alkali resistance, corona resistance, radiation resistance, and has good flexibility and tensile strength, that is suitable for high-speed winding. The fire resistance test shows that the wire and cable wrapped with mica can ensure no breakdown for 90min under the condition of temperature 840℃ and voltage 1000V.
Mica glass fiber refractory tape is widely used in high-rise buildings, underground railway, large power stations and important industrial and mining enterprises and other places related to fire safety and fire saving, such as fire equipment and emergency guide lights and other emergency facilities power supply wire and control wire. Because of its low price, it is a good cable material.
There are many kinds of phlogopite mica tape. It can be divided into: double-side mica tape, single-side mica tape, phlogopite glass mica tape, double-film mica tape, single-film mica tape and so on.
Double-side mica tape: with mica paper as the base material and glass fiber cloth as double-sided reinforcing material. It is mainly used as refractory insulation layer between core wire and sheath of fire-resistant cable. With the good fire resistance, it’s recommended for general engineering.
Single-side mica tape: with mica paper as the base material, glass fiber cloth as single-sided reinforcement material, mainly used for fire-resistant cable as fire-resistant insulation layer. With the good fire resistance, it’s recommended for general engineering.
Phlogopite glass mica tape: with golden mica paper as the base material, glass fiber cloth and carbon free film as single-side reinforcing material, mainly used for refractory cable as refractory insulation layer. With the good fire resistance, it’s recommended for general engineering.
Double film mica tape: with mica paper as the base material, with plastic film as double-sided reinforcement, mainly used for motor insulation layer. Due to the poor fire resistance, it is strictly prohibited in fire resistant cable
Single film mica tape: with mica paper as the base material, with plastic film as single-side reinforcement, mainly used for motor insulation layer. Due to the poor fire resistance, it is strictly prohibited in fire resistant cable
I.Product introduction of single – sided phlogopite mica tape
The single-side mica tape in refractory cable is made of mica paper, single-layer non-alkali glass fiber cloth as reinforcement materials, bonded with high temperature resistant silicone, with good fire resistance characteristics, widely used in fire equipment and emergency guide lights and other emergency facilities power supply and control cable. It also has good flexibility and tension, and can be wrapped by high-speed wrapping equipment.
