A5038 self-adhesive PTFE coated glass fabric combines a high-performance PTFE coating with a strong, flexible woven glass cloth backing. The thin 3 Thou (73 µm) construction delivers outstanding release properties, chemical resistance and electrical insulation, while the silicone adhesive provides reliable adhesion up to 260°C.
This material is suited to demanding industrial applications where a durable, non-stick and heat-resistant surface is required. Dotmar supplies A5038 in standard wide rolls and can provide slit rolls to custom widths, ensuring a practical solution for coating, masking and release applications.
