Description:
The dedicated PTFE tape for SWG is a high-purity (ePTFE) filler material specifically designed for use in spiral wound gasket assemblies. This PTFE tape is made of 100% ptfe，it offers excellent chemical resistance, wide temperature stability, and high resilience, making it ideal for demanding sealing applications in corrosive environments.
Key Features：
Pressure Capability: It can be used under high sealing pressures typical of spiral wound gaskets.
Tape Dimensions: Typically available in widths such as 3.9–4.5 mm or 5.6–6.0 mm, with thickness ranging from 0.5–1.0 mm depending on design.
