Release tape is a self-adhesive, non-reinforced, PTFE tape with silicone adhesive. PTFE release tape is ideal in providing a sealed and released surface on an otherwise porous substrate.
The standard and most popular adhesive type is silicone, which has a maximum working temperature of 230˚C.
Where preferred, the tape is also available with a slightly lower temperature (180°C) acrylic adhesive in lieu of silicone.
