Polyimide Film Tape with Silicone Adhesive resists temperatures of -100 degrees F to 500 degrees F. Used for masking on printed circuit boards to protect gold contacts from molten solder during a hot air wave soldier leveling process. The tape is amber in color and translucent. It is also the ultimate electrical insulating tape and ideally suited for continuous high temperature operation conditions because of its silicone thermosetting adhesive. Widely used in small bobbin wound coils as cross-over insulation and outer protective wrap. Also used as a ground barrier and phase insulation in small high performance specialty coils and motors and for end turn bundling and insulation in small motors. It has an Insulation class of 180 degrees C (356 degrees F) Excellent puncture resistance, as well as, resistance to acids, oils, solvents, aging, staining, and water immersion. Removes cleanly. Continuous service temperature range is -100 degrees F to +500 degrees F. Short term intermittent service can go to 600 degrees F. Dielectric strength is 7500 volts. This product is a cross to 3M92 and 5413, Tesa 4428, and Permacel 221.
