The Difference Between PFA and PTFE Products

The Difference Between PFA and PTFE Products

February 6, 2020

If only the endless number of tubes and hoses that snake through a commercial or industrial worksite had a one-size-fits-all solution when it came to length and attachments. Sadly, that’s not the case, and all those crucial components require a little bit of help to work alongside your machinery. That’s where a good set of PTFE or PFA fittings in San Jose, CA can make the difference between a smooth workday and a real disaster.

But what is the difference between these two popular fitting types, and what purpose do they serve on the job? Read on to find out!

Polytetrafluoroethylene at a glance

Polytetrafluoroethylene—or PTFE for those without a degree in chemistry—was discovered in the 1950s. As you might expect, PTFE fittings have an extremely high resistance to heat and an innately nonstick surface. PTFE products are also referred to by their brand name, Teflon.

Because the melting point of PTFE is so high, it must be formed with extreme care. PTFE fittings begin their life in a powdered form. This powder is mixed, formed and turned into a thick paste. This paste is forged into the final tube shape that goes to work in your factory or worksite.

A quick look at perfluoroalkoxy alkane

Though shorter than “polytetrafluoroethylene,” the word “perfluoroalkoxy” is no easier to spell or pronounce. That’s why it’s most commonly called PFA. PFA fittings in San Jose, CA are known for their incredible flexibility and resistance to chemical degradation. PFA fittings are an excellent choice when a company is funneling potentially toxic or corrosive materials through a tube or hose.

PFA’s primary strength is its ability to be melt-processed, the act by which a liquid substance is formed into a solid structure. Melt-processing allows PFA a higher thermal stability than PTFE. The material also has an improved flow rate.
