Grade references.
Chemours Teflon™ PFA is supplied as pellets (and one powder grade). Three series: the general-purpose 300 series, the HP high-purity series (“New PFA”) developed for semiconductor and other clean applications, and Super PFA with a smoother, lower-permeation surface. MFR is measured at 372 °C / 5 kg.

What we confirm first.
The questions that decide whether a PFA grade fits your line. Having them ready shortens the first exchange.
Purity class required
E.g. high-purity / semiconductor grade vs. general grade
Form and dimensions
Tubing OD/ID/wall, fitting geometry, or pellet grade
Process chemistries and operating temperature the part will see
Documentation the qualification requires
TDS, SDS, CoA, origin
Other fluoropolymer families.
