Heat Resistant Polyimide Silicone Tape (FPI)
Heat-Resistant Polyimide Silicone Tape (FPI) is manufactured using our high-temperature resistant amber polyimide films as the base material, coated with a premium silicone pressure-sensitive adhesive (PSA).
It offers excellent electrical insulation, dimensional stability, and clean removability, even after prolonged exposure to high temperatures. The tape is specifically designed for high-temperature masking, electrical insulation, and protection applications in electronics manufacturing.
FPI tape maintains stable adhesion and mechanical performance under demanding thermal conditions, making it suitable for semiconducor processing, PCB solder masking, electronic component protection, and high-temperature assembly environments.
Thermal Performance
FPI provides outstanding resistance to heat and chemicals.
This makes it ideal for wave soldering, solder dipping, and other short-term high-temperature processes.
