The FH film is a heat sealable film which is made by Polyimide film with one side or double side FEP coated. When combined with FEP resin, the Polyimide film remains excellent heat and electrical properties. This kind of film is widely used in high temperature wire manufacturing. When treated in a high temperature, the film will adhere from one side to another and from film to copper. The well sealed conditions enable the wire to be used in severe environment such as high temperature, under water and oil.
