A5108 (10 Thou) PTFE Coated Self-Adhesive Glass fabric
The A5108 PTFE Coated Glass Fabric roll is manufactured with a medium PTFE content and a silicone adhesive, supplied with a corrugated yellow backing liner. It is mainly used as a high temperature release material in the packaging, plastics, PVC welding, and composite industries, and also performs effectively as a liner in mould release and roller covering applications.

A5108 is a PTFE-impregnated woven glass fabric with a pressure-sensitive silicone adhesive on one side. The glass substrate provides mechanical strength and dimensional stability, while the PTFE coating delivers a smooth, non-stick surface with excellent release properties.
This material performs reliably across a wide temperature range from -73°C to 260°C, making it suitable for demanding thermal processes. Available from Dotmar in standard rolls and custom slit widths, it combines ease of application with consistent, long-lasting performance in industrial environments.

Commonly used as a release liner, heat-sealing tape, and masking material in packaging, laminating, and composite processing. The silicone adhesive and PTFE surface make it effective on heated bars, sealing jaws, and chutes where material build-up must be avoided. It is also applied as a low-friction surface liner in chutes, guide rails, and conveyor systems across food processing, printing, and general manufacturing industries.
Sizes Available
Rolls : 1000mm/1500mm wide x 30m long (other lengths on request) with availability also as slit rolls in custom widths
