Other Characteristics of PFA:
PFA is a copolymer of tetrafluoroethylene with a perfluoralkyl vinyl ether. PFA is a highly durable plastic similar in characteristic to PTFE. With an extremely low apsorption point and permeability levels, PFA could be used for trace element analysis, isotopic seperations, sample digestions and handling of sensitive biological solutions.

PFA for Laboratories:
PFA is commonly used for liners and tubing, making it a valuable laboratory material, particularly because of its excellent chemical resistance. Its high temperature resistance could make it an exellent piece of equipment for any laboratory using liquids at very high temperatures. PFA is autoclavable by steam at 121°C (249.8°F). It can also be sterilized by ehtylene oxide gas or formalin/ethanol chemicals.
Recycling:
PFA does not have it's own recycling code symbol. However, PFA can be recycled into many other products. Recycled PFA can be used for industrial applications. For more information regarding PFA recycling see the Plastic Container Recycling Page
