Thank-Metal Co., Ltd., a Japanese manufacturer of precision machines and metal processing components for various types of batteries, has specified APTIV^TM film in its new line of Tough Tape^TM high-performance pressure-sensitive tape targeted for protective tabs used in cylinder lithium batteries.

The Tough Tape high-performance pressure-sensitive tape features properties that surpass polyimide, PEI and PTFE tapes. When compared to polyimide- and PEI-backed tapes, Tough Tape offers improved chemical resistance, better tear strength, lower moisture absorption, and improved barrier properties. When compared to PTFE-backed tapes, pressure-sensitive tapes made from APTIV film offer superior mechanical properties, improved abrasion resistance, higher dielectric strength, lower smoke and toxicity release, lower permeability, and lower specific gravity.

 “The battery industry is seeking tape products with excellent strength, heat resistance and chemical resistance that could be used in insulation applications,” said Mr. Kobayashi, manager of New Business Development at Thank-Metal. “With the superior mechanical properties of Tough Tape, we are pleased to support this new application area and we are well prepared to meet increasing customer demand now and in the future.”

Tough Tape, made with APTIV film, can be adhered to many different hard mating surfaces such as steel, ceramic or glass. The tapes are available in 25µm backing thickness and in a range of widths depending on customers’ needs.
