TEADIT WASHER TF 1572 SAN Advantages & Physical Properties
Polytetrafluoroethylene.
Polytetrafluoroethylene (PTFE) is a polymer with special chemical resistance and is a widely used plastic in industrial sealing.
The media that can chemically attack PTFE are liquid alkali metals and free fluorine. PTFE has excellent electrical insulating properties, anti-sticking, impact resistance and a very low coefficient of friction.
Illustrate. Tealon TF 1572 SAN is suitable for a wide range of corrosive media, but is specifically formulated to meet NSF-61 standards for drinking water system components from source to tap.
NSF-61 certification provides a high level of assurance that the TF 1572 SAN is safe for use in drinking water service.
The high compressibility of this style makes it particularly suitable for stress-sensitive and/or brittle flange joints, such as glass, ceramic, plastic, etc.
Advantage. Another advantage of the TF 1572 SAN is that it has a strong dielectric rating, making it suitable for isolation kit applications.
Tealon TF 1572 SAN is a structured PTFE gasket that is manufactured by process with a high level of fibrosis to overcome the creep relaxation and cold flow problems associated with common (turned or molded) PTFE plates.
This style is made of virgin PTFE resin filled with hollow glass microspheres.
