Features and Benefits

  • Most outstanding properties are its high dielectric and tensile strength, which make it an extremely durable insulation tape.
  • Length: 33M
  • The high temperature properties of the PTFE and silicone adhesive allow the tape to perform continuous temperatures up to 260℃.
  • A high-modulus tape, PTFE also exhibits low elongation which enables it to be applied with automatic wrapping equipment.
  • The other outstanding features of PTFE tape include chemical inertness as well as low-friction, anti-stick and non-toxic properties, making it the right material for numerous applications. This PTFE tape meets MIL-I-23594 U.S. Government specifications
