Foil Tape for Electronic Heating Wire Sealing Applications

Product Overview

Foil Tape for Electronic Heating Wire Sealing Applications is specifically designed for the insulation, fixation, and shielding requirements of electronic heating circuits. The product features an ultra-thin aluminum foil composite structure, with standard thickness controlled at 0.05mm and certain specifications as thin as 0.025mm, adapting to the internal spaces of compact electronic components. The tape possesses high dielectric strength (≥5kV/mm), effectively isolating current and preventing circuit short circuits. The aluminum layer in the substrate provides electromagnetic interference (EMI) shielding effectiveness with signal interference attenuation exceeding 30dB, protecting sensitive electronic components from external signal influence. The product features static dissipative properties, reducing the risk of electrostatic accumulation during processing and usage. The tape undergoes precision slitting processing, ensuring smooth edges that effectively eliminate fiber shedding or dust contamination, meeting the cleanliness standards of the electronics industry.

Product Advantages

Engineered for modern electronic applications, this tape provides a comprehensive solution integrating safety, precision, and environmental compliance.
