Tac-Tape A5058 is a PTFE-coated glass fabric pressure-sensitive tape, delivering a low-friction, non-stick surface suitable for elevated temperatures. The silicone adhesive system provides consistent bond strength across the full service range without softening or charring.

Dotmar supplies this tape in precision slit rolls, giving you exact widths from 12 mm up to 980 mm with a standard 30 m length. The glass substrate offers dimensional stability, while the PTFE coating resists chemicals, moisture, and UV, making it a durable choice for demanding industrial environments.
