We are one of the leading distributors, stockiest & suppliers of Expanded PTFE Sheet TEADIT 24 SH, which are used in varied industries. Our product manufactured by TEADIT.
Description:
TEADIT 24SH is a large gasket sheet produced from 100% pure, multi-directionally expanded PTFE (Polytetrafluorethylen).
Properties:
Colour: white
Size: 1500mm x 1500mm
Thickness: from 0.5 mm up to 6 mm
Temperature range: -240°C up to +270°C for short periods up to 315°C
Chemical resistance: chemically inert against all substances (pH 0-14), including the most aggressive acids and lyes. The only exceptions are molten alkali metals and elemental fluorine at high temperature and pressure.
Operating pressure: from vacuum up to 200 bar
Aging: TEADIT 24SH is not subject to aging or weathering. It can be stored indefinitely.
Safety: TEADIT 24SH complies to FDA regulations for food, is physiologically harmless and is also suitable for oxygen applications.
Advantages:
● Universally employable gasket sheet for all applications. It is suitable for all types of flanges, nearly all media, a wide temperature range and even for applications with the toughest demands on purity. It is inherently clean and non-toxic.
● The compressed gasket of multi-directionally expanded PTFE has exceptional mechanical strength which enables operation with less creep at higher temperatures than other types of PTFE sheets.
● The excellent malleability of TEADIT 24SH makes repairing of small damages and/or irregularities of the sealing area (flange surface) unnecessary.
● Gaskets cut from TEADIT 24SH are dimensionally stable, i.e. they do not get wider when compressed. This allows narrow flange faces to be sealed safely, i.e. without causing turbulences in the flow of the
media.
● TEADIT 24SH is quick and simple to install. The used gasket can be
removed quickly, easily and without residue.
