TEADIT 25 BI is a multidirectionally expanded gasket-tape, produced from 100 % pure PTFE (Polytetrafluorethylene). TEADIT maintains a quality and environmental management system that is certified according to DIN EN ISO 9001 and DIN EN ISO 14001.
Application areas:
TEADIT 25 BI – due to its excellent malleability – 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 25 BI, 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.
Filter leakage, due to surface irregularities between a lid and a fixed flange, caused contamination in a plant. This increased the risk for chemical burn injuries and corrosion of nearby equipment. The fragility of PVC flanges limited the ability to solve the problem by simply increasing the bo ...
