Product Details
Mica tape, also known as fire-resistant mica tape, is an excellent mica insulation product with good high temperature resistance and flame resistance.
There are three main types of mica tape products of our company: synthetic double-sided mica tape, calcined mica tape, and coated mica tape. These mica tape products have the characteristics of small expansion coefficient, high dielectric strength, high resistivity and uniform dielectric constant, and high heat resistance, the highest temperature resistance is greater than 1000 degrees Celsius.
