- 260℃ Extreme Temperature Resistance Same high heat resistance as traditional Kapton tape, stable during SMT reflow and high-temperature baking
- Zero Light Pollution & No Optical Interference Transparent and colorless, no shadow, no color difference, suitable for lens and display module assembly
- Excellent Insulation & Dimensional Stability H-class insulation, low CTE, no shrinkage after thermal cycling
- Clean Removal & No Residue Stable silicone/acrylic adhesive, no glue residue after high-temperature peeling
Product Overview
Transparent Polyimide Tape (CPI Tape / Clear PI Tape) is a new generation of optical-grade high-performance polyimide tape. Different from traditional amber and black PI tape, it features colorless, transparent and high light transmittance while retaining the original ultra-high temperature resistance and electrical insulation properties of polyimide material.
This clear PI tape solves the industry point of traditional PI tape cannot be used for optical precision products. It maintains stable physical performance under 260℃ high temperature, with no yellowing, no deformation, no light leakage. It is widely used in flexible OLED displays, camera modules, optical lenses, precision electronic assembly and high-end equipment insulation.
