7058 Blue is a premium PTFE (polytetrafluoroethylene) coated glass fabric, combining the high-temperature resistance and non-stick properties of PTFE with the dimensional stability of a woven glass substrate. This material is engineered to deliver consistent release performance across a broad temperature range, from -73°C to 260°C, making it suitable for demanding thermal and mechanical environments.
Dotmar supplies 7058 Blue as part of its comprehensive range of non-adhesive PTFE coated materials, offering reliable, Australian-stocked solutions for conveyor and processing equipment. The blue colour provides visual contrast for alignment and wear monitoring, while the standard roll format (1000 mm wide x 30 m long) supports efficient fabrication and installation.
