TEALON TF 1590 is a structured PTFE - Gasket - Sheet manufactured by a unique process which provides a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with normal (skived or moulded) PTFE sheets. TEALON TF1590 is produced from virgin PTFE resin filled with Silica.
Advantages:
• It is suitable for services with high pressures and temperature, especially in chemical processing and hydrocarbon plants in strong acids (except hydrofluoric), solvents, hydrocarbons, water, steam, and chlorine.
• TEALON TF 1590 is quick and simple to install. The used gasket can be removed easily and without residue.
Hot Compression Test
This performance test measures the behavior of rPTFE and PTFE gaskets in a real world environment. The chart below shows a comparison between conventionally skived PTFE and Tealon. The gaskets we tested simulated a real world application including thermo-cycling. The skived PTFE gasket showed a very high leak rate, losing 60% of its initial pressure by the end of the test.
The Tealon® gasket lost only 6% of its initial pressure by the end of the test and showed a leak 10 times less than that of the skived PTFE gasket. The pictures below, show the gaskets after the test and exhibit the dimensional stability of Tealon as compared to the noticeable creep of the skived PTFE gasket.
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 ...
