Description

Available in 125 microns, this polyimide film is an excellent electrical insulation material, with outstanding thermal, mechanical, chemical and electrical properties. This versatile film has been used in applications where the environmental temperatures have been as low as -269°C and as high is 400°C and can be easily fabricated by a wide variety of techniques e.g. punching, die-cutting and thermal forming. This film can also be laminated, metallised or adhesive coated.
