Teadit® 24 SH is a gasket sheet produced from pure, multidirectionally expanded PTFE, a special production process ensures equal tensile strength in all directions. This makes gaskets cut form Teadit® 24 SH one of the best, most versatile and most reliable gasket materials on the market. Cold flow and creep has been eliminated, gasket parameters have been drastically improved, while all the excellent physical properties of PTFE have been fully retained.

Advantages
• material does not get wider under compression
• easy to cut or punch
• suitable also for enamel flanges and/ or vessels
• compensates for irregularities and/ or damages on the flange faces
• has all inherent advantages of pure PTFE

Application areas

• suitable for all pressure sensitive and stress sensitive connections
• suitable for use with even the most aggressive chemicals
• non-contaminating – appropriate for all applications demanding highest purity
• extremely versatile for flange connections, pressure vessels, chemical reactors and/ or housings of pumps, compressors etc.
• suitable as hand and manhole gasket, heat exchangers, venting systems and many more

Teadit® Metallic Gaskets (Kamprofile) offer outstanding flexibility and recovery, assuring seal integrity under pressure and temperature fluctuations, flange rotation, bolt stress relaxation and creep. Teadit® Kammprofile gaskets are used by the chemical and petrochemical industry, as well as in power stations and refineries, on both standard pipe-work and specialist applications, e.g. shell and tube heat exchangers, etc. Kammprofile gaskets are constructed from a precision serrated metallic core with soft gasket materials – flexible graphite or expanded PTFE – bonded to either side. Depending on the kind of metal used, Teadit® Kammprofile gaskets can be used for all media from pH 0 to 14 Teadit® Kammprofile gaskets can be delivered in different styles and qualities: without outer location ring with integral outer location ring (with preset breaking point) with loose fitting outer location ring.
