Our company sold KAPTON ®, PolyImide (PI) insulating membrane / tape: polyimide film, the choice of insulating substrate "KAPTON ®" for the U.S. Department of DuPont (DuPont ™, Inc.) Registered products. KAPTON ® and a high degree of flexibility and the advantages of anti-puncture, film, flame retardant, high temperature, anti-Plasma, and can maintain a stable electrical performance, great for temperature changes of the electrical components, such as the semiconductor industry, dry-type process ( Dry-Bench) can effectively prevent Arcing and Pealing, sprayed on the circuit board / solder mask covered finger position, finger to prevent contamination or use in multi-layer circuit board of the cooperative industry pressure.

3 Other specifications: otherwise the chemical resistance of No.06-07.: TEFLON ®-PTFE film / sheet / pad / tape Teflon membrane / tape are available.
4 Comparison:
● KAPTON ® film: resistance to temperature 180 ℃ ~ 220 ℃, instantaneous up to -269 ° C ~ 400 ° C, the electrical resistance of particularly good size and species are more widely market liquidity, lower cost, the only high-temperature brittle and easy of.
● TEFLON ® film: resistance to temperature 240 ℃ ~ 260 ℃, particularly good chemical resistance, size and types of small, low market liquidity, higher cost, but with excellent non-combustible properties.
