APICAL® Polyimide: The Right Choice for Pressure Sensitive Tape Applications

Pressure sensitive tape is another major application for APICAL® Polyimide Film. These tapes typically employ one or two mils thick APICAL® Polyimide and use different types of adhesive depending on the application. In the electronics industry, where about half of all pressure sensitive tape is used, APICAL® Polyimide provides the perfect masking needed to protect plated leads on printed circuit boards during wave soldering, where temperatures can reach up to 270°C. This makes APICAL® Polyimide the ideal choice for pressure sensitive tape in high-temperature environments.

Versatile Applications in Electronics and Electrical Industries

APICAL® Polyimide is also extensively used in electrical applications. It serves as a wrapping for armature coils and as a splicing or overwrap tape in insulating applications. The versatility of APICAL® Polyimide Film in these roles further highlights its suitability for pressure sensitive tape, ensuring reliable performance across various demanding scenarios.

Adhesive Compatibility

APICAL® Polyimide can be coated with a wide range of adhesives to suit different needs. Silicone adhesives, with an operating temperature of 180°C, and acrylic adhesives, with an operating temperature of 150°C, are commonly used. This compatibility with multiple adhesive types enhances the adaptability of APICAL® Polyimide for pressure sensitive tape applications, making it a versatile and reliable solution.
