perfluorialkoxy
Perfluoroalkoxy (PFA) is a type of fluoropolymer known for its exceptional chemical resistance, thermal stability, and low friction properties. It belongs to the broader category of perfluorinated polymers, which are characterized by the presence of carbon-fluorine bonds that contribute to their unique performance characteristics. PFA is a derivative of polytetrafluoroethylene (PTFE), another well-known fluoropolymer, but differs in its structure and properties due to the incorporation of perfluoroalkoxy groups along the polymer backbone.
PFA was developed as an alternative to PTFE, offering improved processability and a slightly lower melting
The material exhibits excellent thermal stability, maintaining its properties across a wide temperature range, typically from
PFA is also biocompatible and is used in medical devices such as tubing, catheters, and surgical instruments
