Product  Features ：
Polyimide tubing is produced by spirally winding strips of polyimide film using a unique adhesive for lamination.Tubing made of this material provides greater electrical,physical and mechanical insulation than most known films.Among its outstanding qualities are resistance to radiation and retention of properties through high and low temperature extremes.Polymide films can be used in virtually any combination of plastic films,papers or substrates which we currently spirally wind.This allows us to meet your exact needs when the properties of more than one material are required.
