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.
PTFE high-temperature tapes are widely used for electrical insulation, but high-frequency and high-voltage conditions pose unique risks: electrical breakdown, partial discharge, thermal aging, high-frequency signal loss, and environmental sensitivity. This article explains each risk and how to avoid them.
PTFE impregnation is not limited to fiberglass cloth. This article introduces 7 alternative substrates – aramid, carbon fiber, PBI, porous metal, graphite, asbestos (phased out), and ceramic fillers – with their process features, advantages, limitations, and key applications.
