Product Overview

This shielding film is a heat-sealing type (thermoplastic). Total thickness is reduced by thin-film formation technology. Being lightweight and superior in bending property, it is ideal for shielding mobile devices and various cable materials. It is widely adopted as a shielding material for consumer equipment and flexible flat cables for TVs. Also, the adoption of the SF-FC500, which has achieved 125°C heat resistance upon request for high reliability, has expanded in in-vehicle applications.


  • Ultralight and high bending property(SF-FC700)

    Small in product thickness, lightweight, and superior in bending property.
  • Low-temperature and short-time bonding

    The thermoplastic conductive adhesive facilitates bonding with various base materials.
  • Excellent shield characteristics

    Offers excellent shield performance by the metallic thin film layer.(SF-FC700)

    Aluminum foil (10μm) realizes even higher shielding performance.(SF-FC500)
  • High heat resistance (SF-FC500)

    Achieves 125℃ heat resistance required in in-vehicle applications.
