An important element of High temperature mica wire – mica tape
An important element of High temperature mica wire is mica tape , it used as an electrical insulating material is composed of three parts: mica paper, reinforcing material and adhesive.
The raw materials for making mica are natural mica and synthetic mica. There are many kinds of natural mica. As electrical insulating materials, there are mainly two kinds of muscovite mica and phlogopite mica. At present, the only synthetic mica with practical value is fluorphlogopite. Shown is a comparison of the properties of these three types of mica.
The choice of high temperature mica wire binder is very important
As an adhesive for High temperature resistance mica tape. Except for the requirement of strong adhesive force and softness, it is not sticky at room temperature. Our country has made remarkable achievements in the development and production of High temperature resistance synthetic mica tapes. Because of its superior High temperature resistance properties than muscovite and phlogopite, it is more and more popular in the cable industry. Fongming cable factory currently has such products . This product has begun to enter the international market and has achieved good economic benefits. Therefore, it is necessary to increase publicity efforts and vigorously promote the application.
