Molecular formula :

nature : belt, is a magnetic tape bearing layer to the basement membrane, with the general-a colorless transparent body. Its thickness of 6 to 75 µ m, usually plastic film. Tape mechanical characteristics of good or bad depends on the performance-based materials with the pros, so right with the requirements based films are more stringent. It should be flexible, bright and clean, anti-power, extending small, uniform thickness, not aging, with a small electrostatic temperature and humidity and a small expansion coefficient. Commonly used materials with a cellulose acetate film, polyester film, polycarbonate film, the most widely used is polyester film.
