PI-HB film is Bi-oriented Polyimide Film using an integrated production
system from polymerization to film preparation. Strict quality control
is being practiced. The film has some features including an excellent
combination of mechanical , physical , chemical and electrical properties
in a wide range of temperatures from -270¡æ to 400¡æ
¡ï Maintains excellent mechanical stability£¬dimension stability in the
range of temperatures from -270¡æ to 250¡æ with short-term run ability at
,,,,the temperatures up to 400;
¡ï Strong resistance to radiations and ultraviolet rays;
¡ï Resists high mechanical stress during assembly operations;
¡ï Excellent electrical insulation properties;
¡ï Outstanding resistance to most chemicals, solvents, lubricants and fuels;
¡ï Allows space and weight savings;
¡ï Excellent Tensile Strength in longitudinal and transversal direction;
¡ï UL approved
Flexible Printed Circuit and Insulation materials for heat-resistant electricity
and cable etc.
