5058 belongs to Dotmar’s range of PTFE-coated fabrics, combining a woven glass substrate with a smooth, non-adhesive PTFE coating. The resulting laminate provides a durable release surface with excellent resistance to chemicals, moisture, and temperature extremes.

Sourced through Dotmar, this material benefits from the company’s experience in supplying machined and fabricated engineering plastics to Australian industry, supporting reliable performance in demanding production environments.

Key Features

  • Continuous service temperature from -73 °C up to 260 °C
  • Glass-fibre substrate for dimensional stability and strength
  • Non-adhesive PTFE surface for superior release properties
  • Nominal thickness of 5 Thou (114 µm)
  • Supplied in roll form for ease of handling and converting

Typical applications include release liners for heat-sealing processes, non-stick conveyor belt covers, and protective overlays in packaging and composite manufacturing. Common industries served encompass food processing, packaging, electronics, and general industrial fabrication where a heat-resistant, low-friction surface is required.

Sizes Available

Rolls : 1000mm/1200mm/1500mm wide x 30m long (other lengths on request).
