Title (EN) FRICTION AND RELEASE COATED POLYMIDE FILM FOR ELECTRICAL INSULATION AND THE PROCESS OF MANUFACTURING THE SAME
(FR) PELLICULE POLYIMIDE POURVUE D'UN REVETEMENT DE FRICTION ET D'UN REVETEMENT ANTIADHESIF UTILISEE A DES FINS D'ISOLATION ELECTRIQUE ET SON PROCEDE DE PRODUCTION
Abstract:
(EN) Polymide film possesses a unique combination of properties that make it ideal for a variety of applications in many different industries. The ability of Polymide film to maintain its excellent physical, electrical and mechanical properties over a wide temprature range has opened new design and application areas to palstic films. This invention relates to manufacture of 'Friction and Release Coated Polymide Film for electrical insualtion and the process for manufacturing the same'. It consists Polymide film coated with a special friction coating on one side and controlled release coating on the other side of the Polymide film. Friction coating gives the Polymide film higher varnish absorption properties and the release coating helps in the ease of application.
(FR) Les pellicules polyimides présentent une combinaison unique de propriétés qui les rendent idéales pour une variété d'applications dans une pluralité d'industries différentes. La capacité que possèdent ces pellicules polyimides à conserver leurs excellentes propriétés physiques, électriques et mécaniques sur une large plage de températures a permis de développer de nouveaux domaines de conception et d'application pour les pellicules plastiques. Cette invention concerne la production ainsi que le procédé de production de pellicules polyimides pourvues d'un revêtement de friction et d'un revêtement antiadhésif utilisées à des fins d'isolation électrique. Ce procédé de production consiste à appliquer un revêtement de friction spécial sur une face de la pellicule polyimide et un revêtement antiadhésif de régulation sur l'autre face. Ledit revêtement de friction confère auxdites pellicules polyimides d'excellentes propriétés d'absorption de vernis, tandis que le revêtement antiadhésif facilite l'application.
