Multi-DirectionallyExpanded PTFE Gasket Tape

Description and Applications

TEADIT® 25BI is a multidirectionally expanded gasket-tape, produced from 100% pure PTFE (Polytetrafluorethylen). The whole production process is subject to strictest quality control, registered under ISO 9001.

TEADIT® 25BI – due to its excellent malleability and adaptability – is particularly well suited to compensate for irregularities or damages on the sealing areas, as well as for all stress-sensitive joints. A special manufacturing process results in almost equal tensile strength in both the longitudinal and cross direction. As a result of this, the material does not change its width under compression. This is in stark contrast to normal expanded PTFE tapes! TEADIT 25BI, because of this property, is extremely well suited as a gasket material for narrow sealing areas and in all applications where a defined gasket width (under load) is required. Typical applications are enamelled and glass flanges, heat exchangers, large flanges and containers, pressure vessels, suction filters and strainers, etc.
