Insulating adhesive tape No.3703 series

polypropyleneacrylictransparent

Overview
The No.370 Series is a polypropylene (PP) based adhesive tape offering superior solvent resistance and dimensional stability. It is designed for fixing elements of aluminum electrolytic capacitors and lithium‑ion secondary batteries where solvent resistance and stable dimensions are required.

Features

• High electrical insulation characteristics.
• Good dimensional stability under solvent exposure.
• Available for narrow‑width processing.
• Offered in long standard lengths for continuous production.

Structure
Backing: PP (polypropylene) film.
Adhesive: Acrylic.
