Polyimide Tape


The 1 mil Polyimide backing with silicone adhesive offers outstanding thermal resistance and excellent electrical insulating properties.

This 108ft ( 36 yards)-long tape is cost-efficient compared with Kapton brand tapes, yet does everything a Kapton tape does. 

This tape is used where toughness, puncture resistance, extreme resistance to heat, and flame, retardance are required.


  • Polyimide type is frequently used in 3D printing. It has long and excellent durability for multiple print cycles even without needing to change the tape.
  • High performance, reliability and durability, with a unique combination of electrical, thermal, chemical and mechanical properties.
  • Used for soldering protection, masking circuit boards, electrical insulation and splicing wires.
