Description
This advanced insulation tape consists of E-glass fibreglass fabric coated with PTFE on one side and backed with a high-temperature silicone adhesive. The PTFE surface offers non-stick, low-friction performance, while the fibreglass base ensures high mechanical strength and dimensional stability. The silicone adhesive provides excellent chemical resistance and remains functional across a broad temperature range (up to 260°C), making it suitable for sealing, electrical insulation, and protective applications in industries such as electronics, composites, packaging, and plastics processing. It is also valued for its clean removal, long shelf life, and conformity to complex shapes.
