Stable quality, Priority in high technology for thin paper, Used or mica tape, mica board, High voltage, temp and strength.

our famous logo  

Our transformer insulation paper is the continuous reeled paper made from high quality muscovite, phlogopite and synthetic mica with mechanical pulp methods.

The production process: reduce the mica scrap to powder, make paper,  cut to the demand width and roll paper to finished products.

Our priority is high technology, especially make thin mica paper, even 40gsm is available.

Even if you don't need this thin mica paper, we just want show this mature technology and skill can ensure the stable quality for you. Thanks

Outstanding Character:

1. Excellent insulating property.

2. High Tensile Strength.

3. Good resin penetration and air permeability.

4. Homogeneous distribution of granularity and structure.

5. Widely used in make Mica Plate, Mica Tape and etc.
