A5058 is a self-adhesive PTFE-coated glass fabric that delivers a non-stick, low-friction surface while maintaining excellent electrical insulation. The silicone adhesive system provides reliable bonding across a broad temperature range from -73°C to 260°C, making it suitable for high-heat masking, release liners, and other demanding industrial applications.
Supplied by Dotmar in standard roll widths of 1000 mm and 1500 mm, this 5 Thou (115 µm) material is also available as tape and can be slit to custom widths on request. Australian engineering and manufacturing teams choose A5058 for its consistent quality and the ability to obtain bespoke roll lengths without sacrificing lead time.
