3M 5491

3M 5491 uses an extruded polytetrafluoroethylene (PTFE) film backing.
This tape offers an extremely low coefficient of friction which, in combination with a pressure-sensitive silicone adhesive, creates a smooth, non-stick surface over a variety of substrates to assist in the movement of materials in many types of lay-flat applications
