Seals. As TFM Modified PTFE offers the same excellent chemical resistance and thermal stability as Standard PTFE, whilst delivering improved weldability, lower deformation under load and lower permeability, it is often used in sealing solutions.

TFM (modified PTFE) is copolymerized PTFE introducing an oxygen molecule and results in a higher density material with lower gas permeation, reduced cold flow and a smoother surface finish when machined.

Apr 16, 2021 · TFM (sometimes referred to by the brand name Dyneon) is a second-generation PTFE material that combines the best properties of PTFE (low friction, chemical resistance, high-temperature performance) with better stress recovery and the ability to handle higher pressures.

thermal cycling and well-contained body seals will prevent extrusion into crevices during thermal cycle. Our standard design valves are provided with a 1/8” hole drilled in the stem tang slot.

3MTM DyneonTM TFMTM Modified PTFE Powder TFM 1700 is a non-free-flowing compression moulding powder for applications like shaped parts, cylinders or blocks, skived films of >20 μm, linings in the chemical processing industry (CPI) and seals, and is suitable as basic material for filled PTFE (compounds).

Our 3M™ Dyneon™ PTFE TFM 1600 is an exceptional modified free-flowing compression molding powder for applications such as seals, gaskets, shaped parts, molded cylinders and small/thin walled parts.

Mar 14, 2024 · Modified PTFE or TFM, is a high-density copolymerized material. It has low gas permeation and reduces cold flow. Often used in the medical field as an artificial blood vessel graft and in other applications where biocompatibility is required. …

Jul 21, 2016 · TFM: Widely known by the brand name, Super-Tek, TFM is a hybrid material similar to TFE, but with greater versatility. TFM has a temperature rating of -50 degrees to 500 degrees Fahrenheit, and offers a low friction coefficient at low torques.

Jul 10, 2015 · TFM is a second generation PTFE that includes an additional modifier called Perfluoro (propyl vinyl ether). This modifier makes its polymer structure denser than PTFE, lowering its gas permeability below that of PTFE but not quite as low as PFA. The same wall thickness of TFM has twice the barrier effect as PTFE.
