PTFE is a synthetic fluoropolymer renowned for its exceptional chemical inertness and extremely low coefficient of friction. Often referred to by its brand name, Teflon®, it is the original "non-stick" material.
PEEK is a high-performance engineering thermoplastic known for its outstanding mechanical strength and thermal stability. It is part of the PAEK family and is considered one of the most reliable high-temperature plastics available.
PFA is a fluoropolymer similar to PTFE but offers the significant advantage of being melt-processable. This allows it to be injection molded or extruded into complex shapes while retaining excellent chemical resistance.
PVDF is a highly versatile thermoplastic fluoropolymer prized for its piezoelectric properties and excellent UV resistance. It sits between the commodity plastics and the high-end PTFE/PEEK in terms of cost and performance.
FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene. It is best known for being the most transparent of the fluoropolymers and is easier to process than PTFE.
PCTFE is a chlorofluorocarbon polymer distinguished by its higher mechanical strength and better moisture barrier properties compared to standard PTFE.
