Moldflon™ – The Innovative Thermoplastic Material Thanks to its thermoplastic proc­ essability Moldflon™ opens up new application potential for PTFE, processed from the melt – a new such as complex geometries which dimension in terms of economy and used to be difficult – or impossible processing technology in high- – to achieve by cutting. The innova­ volume manufacturing of PTFE prod­ tion with Moldflon™ consists of the fact that, unlike PTFE, it can be Other options include the extrusion of continuous profiles, fibers and sheets as well as the fabrication of components by means of...

Basic Properties Comparison of physical characteristic values: PTFE, modified PTFE, Mold­ lon™, PFA, MFA, FEP f Moldflon™ is characterized by a well-balanced properties profile. In the area of fully fluorinated PTFE and thermoplastic products it is positioned between modified PTFE and PFA. With a melting point between 324°C and 315°C, it immediately follows modified PTFE.

Compared to PTFE, it Permeation Measuring gas: Helium is a material with a clearly higher barrier effect. As a thermoplastic material that can be pro­ cessed from the melt, Moldflon™, like PFA, has almost no more pore content, and – merely look- ing at the pore volume – one would expect a bigger difference between the two product...
