What is Tesa 66320?
Tesa 66320 is an extremely thin, high-performance single-sided adhesive tape developed for use in electronic, energy storage, and thermal protection applications. Made from a polyimide (PI) film and coated with a special anti-rebound acrylic adhesive, this tape offers outstanding temperature resistance, insulation properties, and chemical stability. Its ultra-thin profile and flame-retardant characteristics make it ideal for battery hemming and electronic insulation.
