PTFE film tape is a premium high-performance tape manufactured with 100% PTFE film backing and silicone adhesive. Widely used in applications requiring high temperature endurance, low friction, and excellent dielectric strength, it’s the go-to choice across electronic insulation, aerospace, packaging, and food processing industries.
High Purity PTFE Film Backing
Crafted from 100% virgin PTFE material, the tape offers unmatched chemical resistance, durability, and superior thermal stability.
Silicone Adhesive Layer
The pressure-sensitive silicone adhesive provides strong tackiness and high temperature endurance up to 260°C.
Ultra-Smooth Non-Stick Surface
Its low friction surface ensures excellent release properties, making it ideal for heat sealing and mold-release applications.
Exceptional Dielectric Strength
Rated at over 4.0 kV/mm, it ensures robust electrical insulation for high-voltage and high-frequency applications.
Thermal Endurance Range
Performs reliably in a wide temperature range from -70°C to 260°C, making it highly suitable for harsh environments.
Chemical Inertness
The tape withstands strong acids, solvents, oils, and corrosive gases, with no performance degradation over time.
