The glass transition temperature (Tg) of silicone pressure-sensitive adhesive is around -120°C – far lower than acrylic adhesives. This ultra-low Tg keeps PTFE high-temperature tape flexible and sticky even at -70°C, preventing brittle cracking and enabling reliable adhesion in cryogenic applications.

The choice of release paper or film substrate and release agent directly impacts the storage stability and peeling performance of PTFE high-temperature tape. This article compares PET vs. kraft paper substrates and silicone vs. fluorinated release agents, recommending the optimal combination for zero-residue peeling and long-term reliability.
