Tealon

Tealon TF1570 | Blue

Tealon TF1570 is filled with glass microspheres and is suitable for aggressive chemical applications. It meets FDA conformance for service within food and pharmaceutical applications. TF1570 is the preferred material for fragile flanges, glass lined equipament or other applications that require higher compressibility.

Approvals: DVGW — TA-Luft — FDA

1570

Tealon TF1580 | White

Tealon TF1580 (White) is filled with barium sulfate and is suitable for strong caustic fluids. It meets FDA conformance for service within food and pharmaceutical applications. 1580 can be used in a wide range of applications due to its vast resistance to most chemical products. It is compatible with strong acids along with strong caustics, making it the most diverse material within the Tealon family. With the white color of 1580, this material is also suitable for processes where contamination is not tolerated. Tealon 1580 meets and has been approved by BAM for oxygen service.

Approvals: DVGW — TA-Luft — FDA — BAM — Chlorine Institute

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.

Thermo-Cycling Leak Test

Temperature cycles from 30º C to 200ºC, with seating stress of 5000psi and using a gasket thickness of 1/8".
