KWO® Universal-B

ePTFE gasket tape and film

KWO® Universal B gasket material consists of mono-directionally expanded PTFE and is available as tape or film according to the required thickness.
In order to ensure a quick installation KWO® Universal B ePTFE tape is fully self-adhesive and cut to the required width. Given its elasticity, the material adapts well to uneven surfaces even at low gasket stress. The tape is easy to install and to remove. Bolt holes can simply be punched after the gasket has been attached.
KWO® Universal B ePTFE tape is widely used as sealant for large frames.
Other than ePTFE tape, the KWO® Universal B product line includes an ePTFE film, which is available with or without self-adhesive backing. The films are designed to wrap, to cover and to coat components of any shape in various fields of application.
