Polystyrene film capacitors, Physics

Assignment Help:

Polystyrene film is extruded flat and free from pin-holes. Film is made from polystyrene granules by extruding heated tube of polymer which is then spread out and stretched state. Heat treatment is given above relaxation temperature after winding film with aluminium foil electrodes. This ensures that the film contracts firmly into contact with electrodes and voids are eliminated. During manufacturing, it is necessary to use dust proof room.

Specifications
