This British Standard specifies requirements for unsintered polytetrafluoroethylene (PTFE) tapes with a mass per unit area within the range 25 g/m to 300 g/m and with a thickness in the range 0.05 mm to 0.25 mm.
The general material requirements for three grades of unsintered PTFE tape are specified, for general or special engineering applications including tail stock sealing, thread sealing and/or as an antiseize agent at temperatures between - 270 ℃ and + 260 ℃.
All grades of this tape are suitable for use with most common liquids and gases.
In addition to the definitive requirements, this standard also requires the items detailed in clause 3 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.
