WebPTFE is a very unusual solid material in that its bonds are among the strongest known (the C—F bond dissociation energy in PTFE is 480 kJ mol −1) while its weak ones are among the weakest of such interactions [4,5] (—CF 2 — interchain van der Waals’ forces are only 3.2 kJ mol −1). PTFE is also unusual from the point of view of the ... WebPolypropylene is a very flexible, soft material with a relatively low melting point. These factors have prevented most people from being able to properly machine the material. It gums up. It doesn’t cut clean. It starts to melt from the heat of the CNC cutter. It typically needs to be scraped smooth to get anything close to a finished surface.
WebPTFE (PolyTetraFluoroEthylene) is a synthetic fluoropolymer of tetrafluoroethylene and contains just two elements; carbon and fluorine. A thermoplastic polymer of high molecular weight, it has one of the lowest friction coefficients of any solid and is virtually chemically inert due to the strength of the bonds between the fluorine and carbon atoms.
