A7039-1 Dark is a self-adhesive PTFE coated glass fabric that combines a woven glass substrate with a PTFE (polytetrafluoroethylene) coating and a high-temperature silicone adhesive. The PTFE surface delivers excellent non-stick and release characteristics, while the glass fabric provides dimensional stability and strength.
This material is suited to applications requiring a durable, low-friction surface that can withstand continuous temperatures up to 260°C. Dotmar supplies A7039-1 Dark in standard roll formats and can provide slit rolls in custom widths to meet specific project requirements, backed by reliable local service and support.
