What are fluoroplastics and why use them?25 mars 2022 à 3h54 Auto & Moto Saïda 120 vues
Fluoroplastics may not be widely known, but in many ways, they are the superheroes of the plastics industry, and incredibly strong.
What are fluoroplastics?
A normal plastic polythene molecule consists of a carbon chain with hydrogen atoms attached. Yet in fluoroplastics, hydrogen atoms are replaced with fluorine atoms, which dramatically changes their properties.
PTFE, FEP, PFA and other fluoropolymers have non-stick characteristics, very high resistance to chemicals and solvents, very high electrical resistance, and incredibly, are ideal for use in very low and very high working temperatures from -200°C right up to +260°C.
By adding extra fillers to the mix, such as carbon, graphite, anti-static and ceramic, it is possible to boost these exceptional properties even further! Find out more about our Fluoroplastic Tubes.
Typically, fluoroplastics do not melt, so they need to be processed using special tooling and techniques. But once this is done, there are many different industries that PTFE, FEP and PFA can be used into great effect.
Being able to function in extremely high temperatures and non-corrosive to all acids, fluoropolymers are often used to make gaskets, vessel linings, pump interiors, washers, rings, seals, spacers, dip tubes and well-drilling components.
Fluoroplastic Films are well used in heated processes within manufacturing and laboratory test environments. In electrics, they are used as excellent insulators for wire and cable wrapping. Being inert, they can be used for chip manufacturing and encapsulating heaters.
