Tac-Tape A5038 is a high-performance pressure-sensitive tape constructed from a PTFE (polytetrafluoroethylene) coated glass fabric substrate with a silicone adhesive. The glass fabric provides mechanical strength and dimensional stability, while the PTFE surface delivers exceptional non-stick properties, chemical resistance, and a low coefficient of friction.

This tape is designed for demanding applications requiring reliable release, heat resistance, and electrical insulation. Dotmar supplies Tac-Tape A5038 in custom slit widths to suit specific industrial requirements, backed by our expertise in engineering plastics fabrication and conversion.

Key Features

  • Silicone adhesive for high-temperature bonding
  • Glass fabric substrate for strength and stability
  • Wide operating temperature range: -73°C to 260°C
  • Thin profile: 3 Thou (73 µm) thickness
  • Available in slit rolls from 12 mm to 980 mm wide
  • Standard roll length 30 m (15 m roll available on request)

Tac-Tape A5038 is commonly used as a release liner, heat-sealing tape, or electrical insulation in packaging, food processing, aerospace, and automotive industries. It is suitable for wrapping rollers, lining chutes and hoppers, and protecting surfaces from adhesive build-up or high-temperature exposure.

Sizes Available

Slit Rolls: min. 12mm up to max. 980mm wide x 30m long (15m roll available on request)
