Expanded PTFE: Advantages for Fragile Flanges

LATTY presents LATTYflon 95 as a pure expanded PTFE sheet offering high conformability and low creep relaxation. Its deformability facilitates sealing contact against irregular or sensitive seating surfaces, without turning a damaged flange into a guaranteed leak-free assembly. Minimum seating stress, gasket thickness, and allowable bolt loading remain critical factors.

Two Explicit Manufacturer Restrictions

LATTY documentation specifies that this product must not be used with fluorinated gases or molten alkali metals. This limitation must be observed, even though PTFE is renowned for its chemical resistance. Any required certifications and compatibility with cleaning agents must be verified for the specific application and grade, without extrapolating from other products in the line.

Comparing Other Expanded PTFE Solutions

An evaluation may include expanded PTFE sheet materials from Durlon or TEADIT, provided their construction and bolt torque data are fully documented. Comparing these against filled PTFE requires a more comprehensive mechanical assessment. Always identify the media, pressure, temperature, flange class, seating surface materials, and torque method before finalizing your specification.

To compare gasket constructions: TEADIT 24SH and TEADIT 30SH. Expanded PTFE is available in various structures and densities. Always verify bolt tightening conditions and flange geometry.
