Tac-Tape A7039 is a high-performance pressure-sensitive tape constructed from a PTFE (polytetrafluoroethylene) coated glass fabric substrate with a silicone adhesive. This combination delivers exceptional release properties, high-temperature resistance, and mechanical durability.
The silicone adhesive ensures reliable bonding to a variety of surfaces, while the PTFE surface provides a non-stick, low-friction release layer that withstands temperatures from -73°C to 260°C. Dotmar supplies this tape in custom-slit widths to meet precise application requirements, drawing on extensive experience in engineering plastics to support consistent quality and fit.
Key Features
- Operating temperature range from -73°C to 260°C

- PTFE-coated glass fabric substrate for durability and non-stick performance
- Thickness of 3 Thou (75 µm)
- Available in slit rolls from 12 mm to 980 mm wide x 30 m long
- 15 m roll length available on request
Tac-Tape A7039 is widely used as a release surface on heat sealing bars, as a non-stick liner for packaging and converting machinery, and for electrical insulation in high-temperature environments. It is suitable for applications in food processing, packaging, aerospace, and general industrial maintenance where a durable, low-friction, and heat-resistant tape is required.
Sizes Available
Slit Rolls: min. 12mm up to max. 980mm wide x 30m long (15m roll available on request)
