Dielectric Films

BIAX DIELECTRIC FILMS are specially designed polypropylene films manufactured by the tenter process on highly specialised equipment in controlled environmental & ultra clean room conditions for a wide range of applications in the capacitors industry.

Biax Dielectric films range includes plain smooth films modified for good metallization and winding hazy/ rough films and metallized (Al, Zn or alloy) films.

Application areas include:
  • Power Transmission & Distribution Capacitors
  • Motor Run Capacitors
  • Power Film/Electronic Capacitors
  • Magnetic Lighting Ballast Capacitors
  • Microwave Oven Capacitors
  • Low Voltage industrial Power Factor Correction Capacitors
  • AC and Pulse Film Capacitors
  • Interference Suppression Capacitors
  • Energy Storage applications
  • Capacitors for hybrid cars
Specifications and Characteristics:
     Thickness : 4* micron to 15 microns
* lower thickness upto 2 micron under development
     Width : As per requirements
     Surface : Smooth/plain (modified for improved winding)
Hazy /rough films (under trials)
     Treatment : As required (inside or outside)
